Legro H ow can the use of "unthinkable" means of warfarebe avoided? How can states successfully observe mutually desired limitationson "taboo" formsof combat?1These questions are importantbecause of concern that nuclear,chemical,and biological weapons and terrorismwill spread and be used. The growingnumber of states-e.g., Israel, Iraq, Libya, North Korea, Ukraine-that have such means of inflictingharm increases the likelihoodthatany futureconflictwill involve a desire for restrictions.Countries may pursue restraintbecause popular opinion vilifiescertainweapons;2 because leaders calculate that escalationwould damage theirdomesticand internationalpoliticalsupport;3or because states fear retaliatoryattacks. Unfortunately,even when nations agree thatlimitationsare desirable, restraintdoes not always endure. A key source of this disparitycan be found in accidentsand inadvertentescalation. In contemporaryaffairs among major powers, the apparent absence of grounds forintentionalaggression, against a backdrop of change and instability,makes the unintended expansion of conflicta centralconcern.4States may not seek a spiral of hostilitybut stillcan stumbleinto escalation. Why? Jeffrey W. Legrois AssistantProfessor ofPoliticalScienceat theUniversity ofMinnesota. I am gratefulto RobertJervis,Ido Oren, ArthurStein, RichardRosecrance,and two anonymous reviewersfortheircommentson the ideas presented here. 1. The term"unthinkable"comes fromHerman Kahn's studyon nuclearwarfare,Thinking About theUnthinkable (New York:Horizon Press 1962). Here the terms"unthinkable"or "taboo" indicate the stigma attached by public opinion and the internationalcommunityto the use of certain instrumentsof warfare.It does not mean thatstates,and especially theirmilitaryorganizations, do not thinkabout, and plan for,theiruse in war. 2. Often thereseems to be littlelogic to such a stigma.For example, in World War II it became acceptable to the allies to roast Japanese soldiers alive in caves with flame throwers,while the use of gas forthe same task was considered by some to be illegitimate.There is a large literature on the "just" use of forcefroma moral or legal perspective.See e.g., Michael Walzer, Justand UnjustWars:A MoralArgument withHistoricalIllustrations (New York:Basic Books, 1977); Geoffrey Best, Humanityin Warfare (New York: Columbia UniversityPress, 1980); WilliamV. O'Brien, The Conductofa Justand LitnitedWar (New York: Praeger,1981). 3. In the 1990-91 Gulf War bomber and missile attacks against targetsin Iraq, the U.S.-led coalitionmade concertedeffortsto avoid civiliancasualties which mightshow up on television and promote opposition to the war. 4. Accidentsand inadvertencehave receivedconsiderableattentionrecently.See ScottD. Sagan, TheLimitsofSafety:Organizations, anidNuclearWeapons(Princeton:PrincetonUniversity Accidents, International Security,Vol. 18, No. 4 (Spring 1994), pp. 108-142 (C 1994 by the Presidentand Fellows of Harvard College and the Massachusetts Instituteof Technology. 108 MilitaryCultureand Inadvertent Escalation1109 An intriguingset of cases fromthe Second World War offersnew insights and leverage on the problem of taboo warfare and inadvertence.5In the interwar years, three means of warfare were especially singled out and denigratedas inhumane and illegitimate:submarineattacksagainstmerchant ships, the aerial bombing of non-military targets,and the use of poison gas. At the outset of World War II, countriesexplicitlyrecognized and desired a distinctlimitor "firebreak"between restraintand escalation in each of the three means of warfare,despite the fact that all were considered militarily significant.Shortly after fightingbroke out, however, submarine warfare escalated beyond restrictions.Strategicbombing,restrainedat first,was later employed extensively.In contrastchemical weapons, despite expectations and preparations,were never used. Accidents and inadvertence,while not always the main factor,were involved in each of these cases.6 How were these incidentsallowed to occur? Why did some unintended events lead to escalation, while otherswere brushed aside allowing restraintto endure? I argue that the main existingtheoriesof inadvertence-Clausewitz's notionoffriction,the securitydilemma,and organizationtheory7-providepoor predictionsforthe events of World War JJ.8I develop and test an alternative approach, organizational culture,that provides a betterexplanation. Military cultures-beliefs and norms about the optimal means to fightwars-are importantbecause they have a pervasive impact on the preferencesand actions of both armies and states. While traditionalorganizational theory Press, 1993); BarryPosen, Inadvertent Escalation:Conventional WarandNuclearRisks(Ithaca: Cornell UniversityPress, 1992); Bruce G. Blair, The LogicofAccidentalNuclearWar (Washington,D.C.: Brookings,1993). 5. Much of the literatureis limitedby its focus on the bipolar U.S.-Soviet nuclear competition. The emergingmulti-polarnuclear world, however, makes the historicalexperienceof countries other than the two superpowers increasinglyrelevant, especially if, as I argue, restraintis influenced by national traits. The narrow concern with nuclear warfare precludes historical analysis of variationsin use in this formof combat because of the welcome absence of instances of inadvertentnuclear escalation. One study that takes a historicalcomparativeperspectiveon escalation is Richard Smoke, War: Controlling Escalation(Cambridge: Harvard UniversityPress, 1977). 6. My broader study CooperationUnder Fire (Ithaca: Cornell UniversityPress, forthcoming) examines the overall patternof cooperation and conflictimplicitin the restraintand escalation of World War II. This articlefocuses on the accidental and inadvertentelements of escalation ratherthan the intentionaldecisions of states to violate limitations. 7. These threeare highlightedby Posen, Inadvertent Escalation,pp. 12-23. 8. A fourthimage mightbe based on a realist"strategicrationality."However, the focus of this essay is inadvertencewhere states do not desire escalation. From the perspectiveof a unitary state, a strategicrationale for accidental escalation makes little sense. Nonetheless, strategic rationalityis discussed at differentpoints below in order to betterdelineate the organizational cultureapproach. International Security18:4 | 110 emphasizes the importanceof formalstructurein causing uniformmilitary behavior, a culturalapproach contends that differencesin beliefcan lead to dissimilaractions.9Militaryorganizationalculturesnot only influencewhat types of accidents mightoccur,but more importantly, what the implications of those incidentswill be forescalation. Where specificmeans of warfareare cultureofa country'skey military compatiblewiththe dominantwar-fighting services, that nation is likelyto take actions that contributeto escalation. In such situations,the militarywill emphasize the antagonisticrole the other side played, encourage propagandisticuse of the incident,and highlightthe advantages in escalation. Yet when a type of warfareis antitheticalto one side's militaryculture, that state will support restrainteven in the face of provocative enemy incidents. It will suppress informationthat might encourage escalation, accept accidents as such regardless of evidence, make effortsto communicategood will to the opposing side, and rejectany internal proposals to seize propaganda advantages. In short,organizationalculture leads to dynamicsin use and restraintthatare not predictedby the randomness of friction,the securitydilemma, or traditionalorganizationtheory. This argumenthas implicationsforboth theoryand policy. Much of the work in the securitystudies literaturehas emphasized the internationaldeterminantsof the use of forcesuch as the militarybalance, the strugglefor security,or the prevailingnorms or laws of war.10This emphasis, however, has tended to ignore importantdomestic determinantsof escalation. The historicalcases below indicate the powerfulinfluenceof organizationaldy9. Whereas a cultural approach predicts that militariescan eitherfosteror inhibitescalation, workin the traditionalschool such as Graham T. Allison, EssenceofDecision:ExplainingtheCuban Missile Crisis (Boston: Little, Brown and Company, 1971); BarryPosen, The SourcesofMilitary Doctrine:France,Britain,and Germanybetweenthe WorldWars (Ithaca: Cornell UniversityPress, 1984); Posen, Inadvertent Escalation;and Richard Betts, Soldiers,Statesmen,and Cold War Crises (Cambridge: Harvard UniversityPress, 1977), anticipates that all militarieswill favor offense and tend to provoke escalation in war. Stephen Peter Rosen, WinningtheNext War:Innovation and theModernMilitary(Ithaca: Cornell UniversityPress, 1991) challenges the monolithicview of organizationsin his study of innovation,which emphasizes the politicsof promotion,measures of strategiceffectiveness,and the managementofinnovation.I argue thatcultureis critical to each of these threefactors. 10.

EscalationI 111 MilitaryCultureand Inadvertent namics withinnation-states.My contentionis not thatmilitariesalways tend to fosterescalation, as traditionalorganizationtheorywould suggest. Rather, the point is that the armed forces, depending on their culture, can either reinforcerestraintor instigateescalation. In the past, countrieshave made considerable effortsboth to reach diplomaticagreements(e.g., the Hotline, the Incidents at Sea accords) and to develop technical procedures (e.g., permissive action links [PALS] on nuclear weapons) intended to control unwanted events. My thesis suggests that leaders concerned with avoiding undesired escalation in futureconflictsmust also pay attentionto and manage, not only the militaryorganizationsthatimplementthe use of force,but also the beliefs and norms that characterizethose organizations.This is no small task and it may demand a new systemof civil-military relations,a topic taken up in the conclusion. I develop this argument by firstexploring the logic of three traditional approaches to inadvertentescalation-friction,the securitydilemma, traditional organizationtheory-and the new one, organizationalculture. These ideas, particularlythe organizationalculture perspective,are then assessed in comparativecases involvinginadvertencein submarine,aerial, and chemical warfare between Britain and Germany in World War II. Finally, the concluding sections draw togetherthe empirical evidence and outline the importof the findingsfortheoryand policy on escalation and restraint. ImagesofInadvertence It mightseem contradictoryto speak of explanations of accidents and inadvertentescalation-phenomena that seem inherentlyunpredictable-but explanations do in factexist. There are two elements demanding explanation. The firstis to account for the originsof accidents-those unintended and unexpected events. The second issue, central here, is how to explain the consequencesof accidents: why some lead to the widespread crossing of a recognizedlimiton war, while othersare ignoredand restraintendures. Four approaches offeranswers: Clausewitz's notion of friction,the securitydilemma, traditionalorganizationtheory,and organizationalculture. FRICTION The most widely accepted theory on accidents is Clausewitz's thesis presented in On War. He posits that accidents are unpredictable.His termfor this is "friction"or "the fog of war." This concept asserts that a varietyof International Security18:4 | 112 factorscan impose themselves unexpectedlybetween plans and actual outcomes. For example, communicationand control of forces are difficultin war; amidstthe chaos of combat,intelligenceis oftenuncertainor misleading; soldiers get scared or tired and make mistakes. Clausewitz writes, "This tremendous frictionwhich cannot, as in mechanics, be reduced to a few points, is everywherein contact with chance, and bringsabout effectsthat cannot be measured, just because they are largelydue to chance."11 His theme is that accidents are random and unavoidable under the demands of battle. Clausewitz's ideas make intuitiveand empiricalsense. By theirverydefinition,accidentshave multipleand oftenunforeseeablecauses. This thesis is somewhat blunt and only gives the most generalnotion of why and how theymightcome about. Nonetheless, the logic ofClausewitz's ideas suggests that unintended escalation is particularlylikelywhen the employment of forceis complex, when the battleis intense, and when information (on what one should do, or what the enemy is doing) is uncertain.12 The mishaps of the 1980 U.S. raid to freethe hostages held in Iran exemplifythe complexity,intensity,and "fog" problems that can beset military operations. The rescue effortwas a high-stakes,high-riskmulti-servicemission in unfamiliarenemy territory.Although the weather forecastwas for clear skies, the helicoptersran into giant dust clouds. At the "uninhabited" meetingspot in the middle of the Iraniandesert,therescue team encountered a bus-load of Iranian travellers.Three helicopters sufferedproblems that grounded them and resulted in the collapse of the overall operation. One helicopterwas forced down by a crew member's simple mistake of leaving a flakjacket or duffelbag over an engine cooling unit.13 No one could have foreseen these particular difficulties,but as Clausewitz warns, given the complexityand pressures of the operation, some undesired incidentswere unavoidable. 11.

Modern day accident theoristsecho Clausewitz's thesisby positingthatunwanted incidents will be more likelyin areas of warfarewhere thereis technicaland organizationalcomplexity. Charles Perrow,NormalAccidents:LivingwithHighRiskTechnology (New York:Basic Books, 1984), pp. 3-4, 330-335. Perrow's argument is that complex organizations that deal with high-risk technologieswill inevitablyincur accidents. An application of this thesis in the militaryrealm is Chris C. Demchak, MilitaryOrganizations,ComplexMachines:Modernization in theU.S. Armed Services(Ithaca: Cornell UniversityPress, 1991). For a test of this thesis vis-a-vis the nuclear weapons accidents of the United States, see Sagan, TheLimitsofSafety. 13. Paul B.

Escalation| 113 MilitaryCultureand Inadvertent THE SECURITY DILEMMA What RobertJervisand others have called the "securitydilemma" links the structureand technologythat characterizea conflictsituation to the possibilityof inadvertence.14This dilemma is produced by the anarchicnature of internationalrelationsthat causes distrustamong states: one states's defensive effortscan make others less secure. The resultinginsecurityleads to action and reaction,producing spirals of hostilityand escalation, ending in an arms race or the actual use of force. It is easy to grasp how the insecurityand uncertaintycharacteristicof ongoing armed conflictwould produce fearon each side thatthe othermight abrogate a pledge of non-use in order to gain an advantage. The security dilemma is magnifiedand escalation made likelywhen defensivecapabilities cannot be distinguishedfromoffensiveones and offensehas the advantage. This structuralcircumstanceseems particularlylikelyto lead to firstuse in two ways. First,when a state's doctrinesor weapons depend on surprisefor effectiveness,that countryhas an incentiveto undertakea firststrike.Recognizing this incentive,an opponent is likelyto be especially nervous about its vulnerabilitiesand will keep a tightfingeron its trigger.15Leaders may face a "use-'em-or-lose-'em"dilemma, in which theyperceive thattheirown securityis endangered if they do not act first;this invites preemptiveescalation. Thus, according to securitydilemma logic, in war inadvertentescalationis likelywhen first-strike or use-'em-or-lose-'emincentivesare present. One example of the dangers of this dilemma comes fromthe fable of King Arthurat the battleof Camlan; a negotiationbetween two suspicious armies erupted into unpremeditatedslaughterwhen one soldier drew his sword to kill a snake and others, thinkingthat a battle had begun, followed suit to defend themselves.16Similarlyin 1890, duringa U.S. Armysearch of a Sioux village, both soldiers and inhabitantshad a tense grip on theirrifles.When one rifleaccidentally went off, a storm of unintended and unanticipated gunfirewas unleashed; thisbecame known as the Battleof Wounded Knee.17 14. Robert Jervis,"Cooperation Under the SecurityDilemma," WorldPolitics,Vol. 30, No. 2 (January1978), pp. 167-214. This dilemma is also capturedby the notion of the "reciprocalfear of surpriseattack"in Thomas C. Schelling,TheStrategy ofConflict (Cambridge:Harvard UniversityPress, 1980), pp. 207-208. 15. Jervis,"Cooperation Under the SecurityDilemma," pp. 187-205. 16. This comes fromHerman Kahn, On Thermonuclear War,2nd ed. (Princeton:PrincetonUniversityPress, 1961), p. 525, citedin Stephen Van Evera, "Causes of War,"Ph.D. diss. (University of Californiaat Berkeley,1984), pp. 40-41, where otherexamples of inadvertencecan be found. 17. Sagan, TheLimitsofSafety,p. 263, describes thisand otherexamples of accidentalescalation. International Security18:4 | 114 The securitydilemma notion captures how insecurityin certain situations can lead to unintended outcomes. ORGANIZATIONS: TRADITIONAL APPROACH A third perspective on accidents and escalation derives fromorganization theoryapplied to professionalmilitarybureaucracies.There are two variants: one that is quite common in the literatureI will call "traditional,"while a second relies on a culturalperspective. The traditionalview of militariesis that,like all organizations,they seek to maximizeautonomyand size and to reduce uncertainty.18 In the armed forces,these tendencies are expected to produce certain common characteristics,such as that militarieswill prefer offensivestrategiesand that they will resist civilian interventionin operaThe underlyingpremise of the traditional planning and implementation.19 tionalperspectiveis thatsimilarlystructuredorganizationswith similarfunctions should have similarinterestsand behavior.20 In a general sense, the traditionalperspectiveexpects escalation because restraintcontradictsthe very nature of autonomy-seeking,offense-oriented, war-winningmilitaryorganizations. Research has indicated that soldiers do not necessarilydesire war, but that afterthe war is under way, professional warriorsdo seek operational autonomy and are inclined to use all means at theirdisposal. Gradualism and restraintcan cost lives and are inconsistent with such hallowed militaryprinciplesas concentrationof forceand the goal of totalvictory.21 From a traditionalorganizationalperspective,thereis little reason to expect any dampening of escalation based on organizationalinflu18. Allison, EssenceofDecision,pp. 67-100. 19. Building on Allison's work, this is the interpretationgiven by Posen, SourcesofMilitary Doctrine,pp. 41-59; Jack Snyder, The Ideologyof the Offensive: and the MilitaryDecision-Making Disastersof1914 (Ithaca: Cornell UniversityPress, 1984), pp. 24-25; Stephen Van Evera, "Why Cooperation Failed in 1914," in Kenneth Oye, ed., Cooperation UnderAnarchy(Princeton:Princeton UniversityPress, 1986), p. 97; Van Evera, "Causes of War," esp. chapter 7; Leon Sigal, Fightingto a Finish: The Politicsof War Termination in the UnitedStatesand Japan,1945 (Ithaca: Cornell UniversityPress, 1988), pp. 19-25. Snyder and Van Evera, while emphasizing the structuraltendencies toward similaritiesamong organizations (e.g., militariesare offense-oriented), seem to allow for the possibilityof a defensive policy, depending on organizational essence. The latterview is more compatiblewith the notion of organizationalculturedeveloped below. On organizationalessence see Morton H. Halperin, Bureaucratic Politicsand ForeignPolicy (Washington,D.C.: Brookings,1974), p. 28. 20. Posen, TheSourcesofMilitaryDoctrine,p. 37 statesthismostexplicitly:"[Organizationtheory] predictssimilarbehavior of units in the contextof similarstructures." 21. Betts,Soldiers,Statesmen, and Cold WarCrises. Escalation| 115 MilitaryCultureand Inadvertent ence.22This perspective, however, would anticipate that accidents and inadvertentescalation are particularlylikelyin ways that are compatiblewith the standard operatingprocedures of the armed forces-i.e., where military organizationshave developed routinesforuse of a particularmeans of warfare.23The proposition that follows fromtraditionallogic is thatinadvertent escalationis more likelyin any means ofwarfarewhere militaryorganizations have developed routinesforuse of thatmeans.24 ORGANIZATIONS: CULTURAL APPROACH An organizationalcultureview of inadvertentescalation predictsa different dynamic. In the last decade, culture has emerged as a central concept in organizationalresearch,primarilyin the fieldofbusiness management.25The reason forthis development was dissatisfactionwith existingstructuraland functionalorganizational studies such as those found in the traditionalapproach discussed above. More specifically,analysts were puzzled why Japanese firmsperformedso differently (i.e., better)when theirformalstructures were so similarto those of Westerncompanies. Many have contended that the answer is organizationalculture:the patternof assumptions, ideas, and beliefsthat prescribehow a group should adapt to its externalenvironment and manage its internalstructure.26 22. Attestingto this expectationare the discussion and examples on organizationtheorygiven in Posen, Inadvertent Escalation,pp. 16-19. 23. For example, during the Cuban Missile Crisis, a routineU-2 mission went ahead as usual, but the aircraftstrayed off-courseover the Soviet Union, contributingto tensions that nearly led to a violent U.S.-Soviet clash. This and other examples are given in Allison, Essenceof Decision,p. 141. 24. Van Evera, "Causes of War," chapter 7, presents a detailed case on how the organizational dynamics of militariesfavorescalation. 25. For an overview of the early evolution of the concept of organizationalculture,see William G. Ouchi and Alan L. Wilkins, "Organizational Culture," Annual Reviewof Sociology,Vol. 11 (1985), pp. 457-483; more recentlysee PeterJ.Frost,et al., eds., Reframing Organizational Culture (Newbury Park, Calif.: Sage Publications, 1991). In securitystudies, the concept of culturehas been applied in differentways. See e.g., Ken Booth, Strategyand Ethnocentrism (New York: Holmes and Meier Publishers,Inc., 1979); JackL. Snyder,TheSovietStrategic Culture,R-2154-AF (Santa Monica, Calif.: The RAND Corporation,1977); Colin Gray,NuclearStrategyand National Style(Lanham, Md.: Hamilton Press 1986); Carl H. Builder,TheMasksofWarAnalysis(Baltimore: JohnsHopkins UniversityPress, 1989). Three notable recentstudies are Elizabeth Kier, Culture, Politics,and MilitaryDoctrine:Franceand BritainBetweenthe Wars (manuscript,January1993); Thomas U. Berger,"America's ReluctantAllies: The Genesis of the PoliticalMilitaryCultures of Japan and West Germany," Ph.D. diss. (MIT, 1992); Alastair I. Johnston,"An Inquiry into StrategicCulture: Chinese StrategicThought, The Para Bellum Paradigm, and Grand Strategic Choice in Ming China," Ph.D. diss. (Universityof Michigan, 1993). 26. The definitiongiven here is loosely based on Edward Schein, OrganizationalCultureand Leadership(San Francisco: Jossey-BassPublishers, 1985), p. 9. Large organizations are rarely International Security18:4 1116 Organizational culture deserves attentionbecause it has an autonomous influenceon the preferencesof militaryservices and ultimatelyon those of states. Cultures are not simply reducible to the desires of individuals who guide organizations,nor to the environmentalcircumstancesin which they exist. Organizational cultures are more than the individuals that run the organizations,in two senses. First,cultureis a collectivelyheld phenomenon. It is not generally the reflectionof a single leader nor is it some simple mathematicalaggregation of many individual beliefs. Second, instead of individuals changing cultures, the reverse is usually the case: people are socialized by the beliefs that dominate the organizationsof which they are part.27Those who heed the prevailingnorms are rewarded and promoted. Those who do not are given littleauthorityor are fired.28 Cultures are also not mere weathervanes to environmentalforces or to The number of large companies that have failed to "strategicrationality."29 adapt to marketchanges are legion.30Organizationalbeliefsoftendetermine which externalcircumstancesget attentionand how costs and benefitsare weighed. Cultures act as a heuristicfor organizationaldevelopment, much the same way a theoreticalparadigm can shape intellectualthought. They provide a limitinglens forinterpreting and selectingwhat is importantamidst uncertainty.31 Environmentaldata and factswhich contradictculturewill be characterizedby one culture,but have several. Often,however,especiallywhen the organization is hierarchicallyordered, a dominant cultureprovides the main creed. 27. One theoristhas noted that one "does not live formonths or years in a particularposition in an organization,exposed to some streamsof communication,shielded fromothers,without the mostprofoundeffectsupon what he knows, believes, attendsto, hopes, wishes, emphasizes, fears,and proposes." HerbertA. Simon, Administrative 3rd ed. (New York: Free Press, Behavior, 1976), p. xvi. 28. For many years, failureto wear a white shirtand dark suit at IBM had hazardous consequences foran employee's career. The company has no writtenpolicy on attire.But according to one formerexecutive, there was "an unwrittendress code that's as effectiveas if it were engraved in steel-or as if it had a loaded gun behind it." See F.G. "Buck" Rodgers, The IBM Way(New York: Harper and Row, 1986). 29. The issue of where culturecomes fromand how it changes is a broad topic thatis generally outside the scope of this paper. I do, however, provide some evidence below that military culturesare not simply a product of the strategiccircumstancesthese organizationsconfront. For a more extensive discussion of organizationalinnovation see Barbara Levittand James G. March, "Organizational Learning," AnnualReviewofSociology,Vol. 14 (1988), pp. 319-340. 30. Many tryto change theirculturesby large-scalepersonnel changes at the top. See Thomas C. Hayes, "FalteringCompanies Seek Outsiders," New YorkTimes,January18, 1993,pp. Cl and C4. 31. Mary Douglas and Aaron Wildavsky, Cultureand Risk (Berkeley:Universityof California Press, 1982), argue that the risks people face and the ways risks are assessed are a product of an earlierculturalchoice. Escalation| 117 MilitaryCultureand Inadvertent discounted as deviant and will be discarded. Likewise, resources are channeled to methods suited to culture,which consequentlyappear more feasible than those deprived of fundingand attention.32 Finally,culturespersist for utilitarianreasons: it can be difficultand expensive to reorientoperational philosophy,especially in a large and complex organization.33 The organizational culture view posits that the pattern of assumptions, ideas, and beliefs that prescribehow a militarybureaucracyshould conduct battlewill influencestate preferencesand actions on the use of thatmeans.34 Each service, repeatedlyfaced with tough decisions about how, where, and when to employ violence, develops a culturethatsets prioritiesand allocates resources.35Where the traditionalapproach would expect all organizational activitiesto be equally likelyto resultin inadvertentescalation, the cultural variant contends that accidents and escalation are likely in those means compatible with beliefs about the "rightway" to fightwars. These "paradigms" provide maps foraction thateitheradvocate or ignore specificmeans of warfare.Those means compatiblewith the dominantwar-fighting culture will be developed and advocated by the military.In such areas doctrine, preparations, and intelligence will be geared towards use, not restraint. Furthermore,those accidents that do occur will be seized on as proof of intentionalenemy use or of an unavoidable intensificationof the war that must be met in kind or bettered. In those types of warfarethat are incompatible with the dominantculture,therewill be littleplanning and advocacy fortheiruse.36More attentionwill be given to avoiding accidents; those that 32.

The degree of impact a particularorganizationwill have on executive decisions seems to vary along at least three dimensions: 1) the extentto which it has monopoly power on issue expertise;2) the complexityof its responsibilities;and 3) the time period available for action. Militariesare particularlyinfluentialin wartimebecause they generallyhave monopoly control over expertiseon the use of force,militaryoperations are complex and not easily understood by non-specialists,and time periods for alteringpre-arrangedplans are limited. For a more detailed discussion of this topic, see Legro, Cooperation UnderFire. 35. Organizational cultures can be discerned in a varietyof sources including interviews,the memoirsof participants,doctrinaldevelopment, organizationalcorrespondence,planning documents, and internalexercises. 36. For example, the traditionalviewpoint has difficulty explainingthe defensiveorientationof some militaries(e.g., the French Army)in the interwarperiod. For an excellentanalysis of this issue, see Kier, Culture,Politics,and MilitaryDoctrine. Security18:4 | 118 International do occur will be accepted as such and managed so as to avert an escalation spiral. In short, the organizational culture perspective predicts a directalbeit subtle-link between militarybeliefs and customs and the likelihood of inadvertentescalation. WorldWarII: Submarines, Bombing,and ChemicalWeapons Each of these perspectiveson inadvertentescalation tells a differentstoryof why states unintentionallycross fire-breaksin the midst of an on-going conflict.How the four approaches account for the actions of the two main antagonists of World War 11-Britain and Germany-is examined below in more detail. The cases deal with three areas of combat-submarine attacks on non-combatants,the bombing of civilians, and chemical warfare-that were taboo means of combat during the interwarperiod. These cases all occurredwithin the same conflict,and thereforedifferencesin what was at stake cannot explain the outcomes. They include both situationswhere inadvertentescalation took place as well as when it did not. These cases involve two aspects of accidents: theiroriginsand theirconsequences. In the submarine warfaresection, the main focus is on origins and covers three situations that had differentoutcomes: an accident that broke a taboo, an accident did not involve taboos, and an "accident waiting to happen" thatwas avoided. Withregardto strategicbombingand chemical warfare,the main interestis the consequences of the accidents: why did some lead to escalation while othersdid not? I pay more theoreticalattention to organizationalculturebecause it is a newcomerand untested;nonetheless, evidence for competing explanations is considered, particularlywhen they offera compellingcontrastingpredictionof the event. SUBMARINE WARFARE: ACCIDENT VS. NON-EVENT The submarinein World War II became known as the "viper of the sea" and its use against merchantand passenger ships was reviled. At the London Naval Conference of 1930, rules that had been formulatedand generally approved at the 1922 Washington Naval Conference were accepted into internationallaw. These rules prohibitedsubmarinesfromsinkingmerchant or passenger ships withoutprovidingforthe safetyof the crews and passen- EscalationI 119 MilitaryCultureand Inadvertent gers.37This hampered the submarinesomewhat because it mightbe vulnerable to aircraftand otherships when heeding the required search and safety provisions. Nonetheless, all the major powers supported the treaty.Despite the collapse of other negotiationsand agreements,in 1936 the major powers-including Britain and Germany-reaffirmedtheir commitmentto the rules in the London Protocol. A close inspection of three situationsof submarinewarfareinvolvingGermanyand Britainsuggests how organizationalculturecan generateaccidents. The most infamous accident of World War II submarine combat was the sinking of the passenger liner Atheniaby a German U-boat at the start of hostilities.In the second case, one Britishsubmarine sank another,and the thirdwas a historicalnon-event: a Britishsubmarine adhered to the rules despite strong incentives to torpedo a German liner. The four approaches offerdifferentpredictionson these cases. Clausewitz's frictionthesis would anticipate an equal likelihood of escalation, given that the situations were comparable in intensity,complexity,and uncertainty(e.g., clarityof battle instructionsand abilityto identifyfriendor foe). Similarly,traditionalorganization theorywould also predictescalation in all cases because both navies had organizational routines torpedoing ships and were eager to join the fight.Conversely, the securitydilemma image would predictno accidental escalation: the submarinesfaced neitheruse-'em-or-lose-'emnor preemption incentives.That is, theywere not put at riskthemselvesby not attackingbut instead waiting to confirmthe identityof the enemy as eithercombatantor civilian,as directedby internationallaw. Organizational culture provides the best explanation in that it correctly predicts that there would be escalation in Germanywhere unrestrictedattacks were central to naval warfarethinking,but not in Britainwhere the Royal Navy belittledthe value and threatof anti-tradesubmarine warfare. Here is what happened. GERMANY S SUBMARINE ACCIDENT. When GermanystartedWorld War II by attackingPoland, strictorders had been issued to the U-boats that the war was to be conducted with meticulous restrainttowards merchantand passenger ships in accordance with internationalagreements. Hitler hoped to 37.

Security18:4 | 120 International avoid conflictwithBritainand America.38In WorldWar I, unrestrictedattacks by German underwaterboats had increased animositieswith the formerand led to hostilitieswith the latter,a developmentthatsignificantly contributed to Germany's defeat.39Hitler hoped to avert a repetitionof history and thereforerequired restrictionson submarinewarfare. At the startof hostilities,eighteen of Germany's twentysix ocean-going U-boatshad already takenup action stationsaround the BritishIsles.40One of the submarines was Joseph Lemp's U-30 on patrol 250 miles northwestof Ireland. On the evening of September3, 1939, the day Britaindeclared war, Lemp located a potential targetand identifiedit as enemy. The vessel was indeed British,but it was the passenger liner Athenia.The crew aboard the Atheniaknew that war had been declared, but they did not worry about U-boat attacksbecause they believed the ship was protectedby the London Protocol.41 Lemp's U-30, however, spit out two torpedoes that burst the vessel. 1088 passengers took to lifeboats,112 went to the bottom.The sinking of the Atheniacontributedto the onset of unrestrictedsubmarinewarfare.42 How can this incident be explained? It is probable that the "fog of war" had somethingto do with it. The young captain Lemp was probably tense in the face of possible enemy contactand not thinkingas clearlyas he might have been. It is unlikelythat he purposely blasted a passenger liner. Since accidents are inherentlyundesired and are more likely in times of tension and confusion,it is difficultto "falsify"Clausewitz's frictionthesis. Maybe Lemp just made a mistake.But simplyto blame "operatorerror"is to conflate human presence with causation.43We must ask if there was evidence to suggest thatfactorsotherthan pure chance under complexitywere at work, 38.

Britainclaimed that the incidentwas intentionaland implementedits own set of defensive measures, some of which were violations of the spiritif not the letterof the London Protocol. German submarinersused the Britishmeasures to argue to theirsuperiors that they must be allowed to attackmerchantvessels withoutrestrictions.Germanywas largelydoing so against Britainby October of 1939, while Britaindid not do so against Germanyuntilthe springof 1940. 43. When accidents happen thereis a tendencyto focus on human erroras a cause, ratherthan on other underlyingcauses that would tend to produce incidentsregardless of the individual involved.

Escalation| 121 MilitaryCultureand Inadvertent and whether certainpredilectionstended to push randomness and human in a particulardirection. fallibility The environmentof combat that evening was not particularlysuited to "friction"in the formof Lemp's misidentification. Although Clausewitz had much more in mind than the weather, the analogy of "fog" does not fit.144 The eveningwas clear,makingmisidentification unlikely.Nonetheless, Lemp claimed that he thoughtthe Atheniawas an auxiliarycruiserbecause it was zig-zaggingand showing no lights,neitherof which was true. Furthermore, Lemp's U-boat closed to such a short distance that it could not easily have missed the outline of the safetyboats and the lack of guns that marked the ship as a passenger liner.45Hitler's demand for restraintwas also clearly communicatedto the U-boat commanders. The submarineswent to sea with orders to heed the submarinerules, and this orderhad been repeated at the veryoutset of World War 11.46Finally,therewere no strongsecuritydilemma incentives to escalate: the Nazi submarines were not at risk by avoiding attacks on non-combatantsand would stillbe able to impair Britishtrade if they decided to do so at a later time.47In Lemp's particularcase thereis no evidence thathe thoughtthe Atheniahad detectedthathis U-boat was in the area. Thus the source of the U-30's action was not a perceived "us or them" dilemma as if, forexample, the Atheniahad been a cruiserthat spotted the U-boat, forcingLemp to choose to kill or be killed. Neither frictionnor the securitydilemma accuratelycapture the dynamicsof the Atheniaaccident. 44. Clausewitz, On War,p. 120 writes, "One [source of friction],forexample, is the weather. Fog can preventthe enemy frombeing seen in time,a gun fromfiringwhen it should, a report fromreachingthe commandingofficer.Rain can preventa battalionfromarriving,make another late by keeping it not three,but eighthours on the march,ruin a cavalrychargeby bogging the horses down in mud, etc." 45.

The orders were laid out to the commanders as they put to sea in August and Donitz reminded his captains of that order by wire on September3, 1939.

They were more vulnerableby followingthe rules than by not doing so; however, restraint was centralto Hitler's grand strategy.With immediateunrestrictedwarfare,the U-boats could have scored a few easier kills rightat the beginningbeforeBritaincould organize its convoys and defensivemeasures, but no significantstrategicadvantage was expected fromsuch action. Germany only had some 26 ocean-going U-boats at the startof war, just one-thirdof which could normallybe on stationat a time. Donitz argued 300 would be needed to get the job done. See "Gedanken uiberden Aufbau der U-Bootswaffe,"Memo by Donitz, September3, 1939, RM 7/891,Bundesarchiv-Militararchiv, Freiburg,Germany(hereafter,BA-MA). Security18:4 | 122 International From an organizationalcultureperspective,however, the incidentis less puzzling. The cultureof the U-boat corps ofwhich Lemp was a partis central to his subsequent "mistake."48 To a degree not seen in any other country, Germany had a vibrantpro-submarineculturewithin its maritimeforces.49 Even though this culture was suppressed for a good part of the interwar period due to internationaltreatiesand internalpolitics,the submarineranks served as a magnet for some of the most ambitious and talented officersin the Navy. Karl Donitz, commanderof the U-boats, sought to infusehis men withan offensive,anything-is-possible spirit.He led the revivalof the World War I U-boat doctrinebased on an anti-tradeoffensive,one that seemed at odds with the pledge to adhere to the submarinerules.50 In light of this culture, the Atheniaincident is not surprising.Lemp was zealously implementinghis training.Germany's"sea wolves" were firstand foremosttaughtto be aggressive,and not to miss opportunities.51 The notion of differentiatingattacks was not ingrained in the training of the U-boat mariners,which is why they had to be given instructionson the eve of war that explained the procedures forheeding the submarinerules.52But Lemp violated the restrictionsby sinking the Atheniain a situation where there was every reason, except organizational predisposition,to show restraint.53 48. In thiscase, as in otherswhere the military'spreferredway of war favorsuse and escalation, the distinctionsbetween culturaland traditionalorganizationtheoryargumentsare not discernible and thereforeI do not address the latter. 49. Germanyalso had a strongbattleshipculture.But the submarinehad a respected tradition and valued role. This contrastssharply with the interwarexperience of countriessuch as the United States and Britain,which ignored the underwaterboat, despite its potentialvalue in a war with Japan. 50.

One naval staffmember advocated giving submarines permission to sink darkened ships withoutany warning.Due to the "politicalsituation,"the possibilitythatanotherincidentwould generate internationalopposition, this could not be completelyapproved. The suggestion was made thatthe Navy leadership give its "silentapproval" to attackdarkened ships in areas where only Britishvessels operated. The one conditionwas that the submarineshad to claim in their war diaries that any sunken merchantvessels had been mistaken forwarships. This is what Lemp claimed and what Padfield,Donitz,p. 193, says was officialNavy policyin such situations. See "Forderungen des B.d.U. und militarischeMoglichkeitender Durchfiihrung,"September Escalation| 123 MilitaryCultureand Inadvertent When news of the Athenia'sdestructionreached Germanyon the day that Britaindeclared war, Hitler and Raeder, the head of the Navy, were convinced that it could not have been caused by a German U-boat, given the aims of the Third Reich and the explicitinstructionsissued. Only Donitz, the trainerof the U-boat captains and crews, thoughtthatit mightverywell have been one of his captains, despite instructions,who sank the passenger liner.54 The U-boats' war-fighting dogma meantthatsuch an "accident" could be expected. BRITAIN S SUBMARINE ACCIDENT AND NON-EVENT. Britain'sbehavior in submarinewarfarecontrastssharplywith thatof Germany.The Royal Navy had dramaticallydifferentbeliefs about the utilityof the submarine. In Britain, the battleship was considered the "final arbiter" of naval combat and it dominated the war-fightingcultureof the BritishNavy.55This culture,embodied in doctrine and plans, belittled submarine warfare, particularly against commerce. The underwaterboat was regarded as the tool of weaker powers, not of mightyBritain.56Sight unseen, the submarine could strike without warning at undefended merchantvessels and even at the proud warships. Not only was it a threatto the war fleet,but it also required that warships be engaged in less heady tasks, such as accompanying convoys, when theyotherwisewould be seeking battle. The Royal Navy did not train submarinersnor develop boats to attackcommerce.Submarineswere meant to be used primarilyforintelligenceand, when they were lucky enough to get the opportunity,occasional attackson enemy warships.57 22, 1939, RM 7/844,BA-MA.

The originof thisbias was not simplygeo-strategicadvantage; i.e. thatBritainwas an island power dependent on sea tradeconfronting Germany,a continentalstatethatwas less vulnerable to sea interdiction.Afterall, the Royal Navy's main expected opponent untilthe late 1930s was Japan, a countryvery vulnerable to an anti-commercecampaign. Nonetheless, despite the fact that the UK did not have and could not affordthe battleshipsto take on Japan in the Pacific, the Navy did not seriouslyconsider using cheaper submarinesto blockade the island. 57. The Britishbelieved that the submarine was not a threatto battleshipsbecause U-boats would be detected with the sonar device called "ASDIC." But because of the cultural bias stressingthe inferiority of submarines, ASDIC did not receive adequate criticaltestingand its flaws were not appreciated.

Security18:4 1124 International The influenceof cultureon unintended Britishactions is especially apparent when contrastedwith the German navy's actions. As with Germanyand the Atheniaincident,the firstsubmarine attackby Britainwas also an accident. On September 10, 1939, the Tritonmistakenlytorpedoed another En- glishsubmarine,Oxely.58 was actingin accordance Like the U-30,theTriton with its organizational culture. Each inadvertentlydestroyed a ship, but it was the type of vessel each had been trained to attack. Britishsubmarines had a legacy of successful anti-submarinewarfare(ASW) in World War 1.59 In comparison, German strategywas based on an anti-merchantoffensive. This differenceappears to have been reflectedeven in the physical structure of the submarines. The acoustical detection array in German U-boats was designed for an anti-shippingrole, while in Britishsubmarines it was for attackingotherunderwaterboats.60Froman organizationalcultureviewpoint it is not surprisingthat the first"accident" of the war fora Britishship was the destructionof a friendlysubmarine,while Lemp's errorwas an "out of bounds" passenger liner. The differencebetween Britain and Germany is just as evident in the accidents that did not happen. Britishsubmarines incurredno Atheniaincident despite opportunities.61For example, when the British submarine Salmon sighted the German passenger liner Bremen2000 yards away on December 12, 1939, a replay of the incidentinvolvingthe Athenia(which had been only 800 yards fromthe U-boat) seemed likely.Yet the Salmonsurfaced and ordered the ship to stop forthe search and seizure proceduresthatwere mandated by internationallaw. Unexpectedly,however, a Luftwaffeplane appeared and chased the submarine off.62Ironically,the Bremenwas being used as a troopshipat the time and thereforewas a legitimatetarget,which 58. The storyof thisincidentis told in A.S. Evans, BeneaththeWaves:A HistoryofH.M. Submarine Losses(London: William Kinder, 1986), pp. 195-199. 59. The day beforethe Oxelywas destroyed,AdmiralWatson, the commanderof the submarine force,requested thathis boats be used more in an ASW role.

The captain of the Salmonnoted, "I had no special instructionswithreferenceto intercepting Bremenand considered myselfbound by internationallaw, a rigidadherence to which had been specificallystressed to submarine commanding officersat the beginning of war."

MilitaryCultureand Inadvertent Escalation| 125 the Salmoncould have easily torpedoed fromthe safetyof the ocean depths.63 The differencebetween Britain's and Germany's accidents is inexplicable froma traditionalorganizationalperspective. Both navies had adopted the London Protocol as part of theirorganizationalrules, but beliefs on how to fighta war-and the typesof accidentsthatoccurred-diverged. As a cultural approach expects,Britain'sbehaviorreinforcedits restraint,while Germany's provoked an accident thatviolated taboos. STRATEGIC BOMBING: VIOLATIONS IGNORED OR RECIPROCATED From20,000 feetoffthe ground, the familiarsurroundingsof life-buildings, homes, cars-appear unnaturallysmall. Perhaps this perspectiveeased the task of the young aviators of World War II who were ordered to flattenthe homes and habitationsof enemy civilianshundreds of miles behind the front lines. Althoughthis practicebecame commonplaceduringWorldWar II (and in many conflictssince), in the 1920s and 1930s it was considered barbaric and potentiallyavoidable. Statesmen made considerable effortsboth to reduce air armamentsand to find ways to regulateair attacksby agreeing on rules and restrictions.64 The main distinctiontheyhoped to enforcewas that between civilians and combatants. No officialtreatieswere concluded, but Britainand Germanywere able to reach accord at the beginningof the war to avoid bombing undefended civiliansand cities.65That pact retainedlegitimacy for the firstnine months of conflict,but as we will see, it did not survive the war. In the strategicbombing cases, organizationalculture played the pivotal part, not necessarilyby causing accidents as in the submarinecases above, but instead by affectingthe responses of states to the incidents-i.e., either to use accidentsas justificationforescalationor,by ignoringthem,to reaffirm restraint.Consider, forexample, the differencein the responses of Germany and of Britainto the other side's transgressionof a major limitationin the air war. In one case, Britain'sbombing of the German homeland broughtno 63. Nigel John Gilbert,"BritishSubmarine Operations in WWII," UnitedStatesNaval Institute Proceedings, Vol. 89 (March 1963), p. 73. 64.

Security18:4 1126 International comparable response; Germany virtuallyignored the event. Yet when Germany accidentallytransgresseda second limitationon the bombingof capital citieslaterin the war, Britainresponded immediately.How can these different outcomes be understood? Organizational culture predicts correctlythat Britainand Germany had differentways of warfarethat accorded differentimportanceto a strategic offensiveaimed at civilians. That contrasthad a considerable impact on decision making and events. The otherperspectivesare less precise in their predictions. The frictionhypothesis would anticipate escalation fromboth participants,particularlyin lightof the technicalcomplexitiesof navigation and precision bombing in the early war period. Likewise, traditionalorganization theorywould also expect both to escalate since both the RAF and Luftwaffehad organizational capabilities and plans for strategicbombing. The securitydilemma argumentexpectssimilarbehaviorfromthe opponents, but in the opposite direction,toward restraint:there was not a strongsurprise-attackor preemptive incentive to initiatestrategicbombing since no single attack could cause a devastatingamount of damage, and there were few penalties involved in continuingrestraintto ascertainif the enemy had actually-even if accidentally-violated restrictions.Yet while Germany showed restraint,Britainescalated. On the nightof May 11GERMANY S RESPONSE TO BRITAIN S FIRST ATTACKS. 12, 1940, RAF bombers undertook, possibly accidentally,the firststrategic raid of the war in an attack on Monchen-Gladbach in Germany. Another RAF assault on Aachen and Monchen-Gladbach took place on May 14-15.66 The officialgo-ahead forthe RAF strategicoffensivewas given on May 15. What is of interesthere is the German response: therewas none. The Germans undertook no immediate retaliation,in kind or otherwise, against Britain,neitherforthe earlier,possibly accidental,raids, nor in response to the approved offensiveafterMay 15. The Britishhistoryof the Luftwaffe pointsout thatin the entire1940WesterncampaignthroughthefallofFrance, 66. Because the Cabinet was debating on a daily basis whetherto undertakethese raids, H.W. Koch, "The StrategicAir OffensiveAgainst Germany:The EarlyPhase, May-September1940," TheHistoricalJournal,Vol. 34, No. 1 (1991), p. 127, has speculated thatBomberCommand acted on its own authority.The evidence, however,is not conclusive. The factthatlittleirritationwas expressed at the Cabinet meetingon May 15 when the Secretaryof State forAir mentionedthe May 14-15 raids suggests that,at least by thatdate, some sortoflimitedoperationwas approved.

MilitaryCultureand Inadvertent Escalation| 127 German bombers were not used strategically,except during one four-day period in Junewhen they attacked the French aircraftindustryin Paris and fuel dumps in Marseilles.67The Nazis were, of course, aware of the RAF's attacks as was noted in reportsby the securityservice of the SS.68 Hitler himselfallegedlydismissed the raids at one pointas inadvertent.He assumed that the attacks on German territory were the result of someone losing his head due to the pressure of the Battleof France, or that the RAF had acted on its own. He saw no need to retaliatein kind.69Despite the factthatit had been made clear that its restraintwas contingenton reciprocity,Germany simply ignored the Britishactions. Why did reciprocalescalation not occur immediately? A pivotal factorin this restraintwas the organizational culture of the Luftwaffe.Unlike the RAF, Luftwaffefaithin strategicbombing-particularly in a civilian-targetedmorale bombing campaign-never took hold. Germany's strategicculture, of which the Luftwaffewas a part, was land-oriented and heavily influencedby a traditionalarmy outlook. Like the RAF, the Luftwaffewas an independent service in the sense that it was organizationally separate fromthe Army and Navy and not subordinate to their orders. Nonetheless, cultures oftenrun deeper than formalstructuresand the Luftwaffewas constrainedby Germany'scontinentalorientationto combat. The German Air Force did not prepare equipment or plans to wage the type of large-scale air assault required forbombing and particularlyforan unrestrictedcampaign. Instead, doctrine was oriented more towards supportingthe land battle.70Even the German heavy bombers best suited for 67. BritishAir Ministry,The Rise and Fall of the GermanAir Force,1933-1945 (New York: St. Martin's Press, 1983 ed.), p. 72. There is, however, a debate on whether the prior German attackson Warsaw and Rotterdamwere against "defended" citiesand thus permissibleor were instead simplyillegitimateterrorraids.

WilliamsonMurray,TheLuftwaffe (Baltimore:Nautical and AviationPublishingCo. of America, 1985), esp. pp. 1-23, argues thatGermanydid have a strategicbomber emphasis. My view is thatwhile a strategicmission-orientedsub-culturecertainlyremaineda part of the Luftwaffe, it did not take rootand dominate the organizationas in Britain.Germanplanningand operations consistentlylisted the hierarchyof Luftwaffe'saims as: 1) the destructionof enemy airpower; then 2) support of the Armyand Navy; and finally3) tasks which mightbe considered strategic bombing. See "Instructionsof the Commander of the Air Force forthe Conduct of Operations in the InitialPeriod of War," November 18, 1935, as reprintedin Karl-Heinz V6lker,Dokumente Security18:4 | 128 International strategicbombing were required to have dive-bombingcapabilities,a specificationthat hindered their strategicbombing effectiveness.71 Thus when Britain'sbombs fell on the Ruhr in the spring of 1940, Germany ignored them. The Luftwaffewas absorbed fulfillingits established role of helping the ground forces advance in assault on France. Even when France was defeated and the Luftwaffewas no longer occupied with its part in that victory,German restraintin strategicbombing endured.72 BRITAIN S RESPONSE TO GERMANY S ACCIDENTAL RAID ON LONDON. Compare the German reactionto escalation with the Britishresponse to an accidental German raid that appeared to breach the restraintstillin effecton bombing capital cities. On the night of August 24, 1940, twelve German bombers overshottheirintended targetsconsistingof aircraftfactoriesand oil refineries located at Rochester and Thameshaven, twentymiles east of London. Instead they dropped theirloads on London, settingoffa chain of reprisals that ended any hope forrestraintin strategicbombing in the Second World War.73 Britaindid not ignorethe event as Germanyhad done in Britain'sbombing, but instead seized on it as an act that required response in kind. The next day Churchillcalled forretaliationand some 100 bombers were dispatched explains that against Berlin. Websterand Frankland's StrategicAir Offensive escalation was motivatedby the prime minister'sdesire that "the Germans get as good as they were giving."74 Perhaps in the heat of battle (with its und Dokumnentarfotos zur Geschichte der DeutschenLuftwaffe (Stuttgart:Deutsche Verlags Anstalt, 1968), esp. p. 478; "Aufmarsch-und Kampfanweisungen der Luftwaffe:Weisungen fur den Einsatz gegen Osten," May 1939, RL 2 II/21, BA-MA; FuhrerWar DirectiveNo. 16, "Preparations fora Landing Operation Against England," July16, 1940. 71.

But this does not explain why, even afterit became clear in Julyof 1940 thatBritainwould not yield and Germanywould have to fight,the Luftwaffe'sassignment was firstto defeat the RAF, then to assist the army and navy in an invasion. Terrorbombing was to be used only in retaliation. 73. Koch, "The StrategicAir OffensiveAgainst Germany,"p. 137; Boog, "The Luftwaffeand IndiscriminateBombing to 1942," p. 389.

Britain may have known frominterceptedmessages that Hitler had forbidden the Luftwaffeto bomb London.75 Yet even without such intelligence,there was good reason to suspect an accident. The unintended foray involved twelve planes which caused light damage and only four fatalities,hardly the type of decisive operation to be expected froma purposeful breach of this importantlimitation.76 Churchillhimselfhad earlier downplayed the gravityof the German raids, noting that very few people were affectedby any one attack.77Moreover,in July,well beforethe German assault, Churchillhad already shown an interestin bombing Berlin. At that time he expressed interestin being able to respond to German attacks on London. But he also gave a planning date of September 1, suggesting that his intentionswere not necessarilydependent on German actions.78 Why did Britaindecide to escalate, breakingthe last taboo against strategic bombing? This is a question of considerable historicalcontroversyand not one easily answered with the evidence available. While there are many argumentsabout what motivated Churchill(not the least of which was his personal predilectionto seize the initiative),what is clear is that his outlook and options were influencedby RAF culture.79From the end of World War 75.

George Quester, Deterrence Before Hiroshima:TheAirpowerBackground ofModernStrategy (New York: Wiley and Sons, Inc., 1966), pp. 117-118, suggests a strategicrationaleforescalation. At the time,FighterCommand was under pressure due to Luftwaffeattacks.Churchillrecognized that command of the air was the key to Britain'sdefense: if FighterCommand failed, Britain was lost. Thus to buy Fighter'Command breathingroom, it is argued, Churchill purposely attacked Berlin in order to draw the Luftwaffe'sattacks on the Britishcapital and away from Security18:4 j 130 International I, Britain's Air Force had promoted and institutionalizeda philosophy of strategicbombing, whose central tenets were that the best way either to preventor to win a war would be to threatenor launch a massive assault on the enemy's sources of power. This included both deprivingthe enemy of the physical means to fightand breakingits morale to continue the battle. Hugh Trenchard,the Chiefof the Air Staff(CAS), had no doubt about which was more important:"The moral effectof bombing stands undoubtedly to the materialeffectin a proportionof 20 to 1."8? This philosophy,effectively A cultivatedin the organization,was well-suitedto unrestrictedwarfare. The RAF's preferencesmade themselves feltin a number of ways. Air Force officialshad been directlylobbyingforescalation since the invasion of France, arguing that the battle had to be taken to the German homeland. RAF Intelligenceboldly asserted that large "moral effects"were resulting fromits bombing operations, a conclusion that seems to have been driven more by wishful thinkingthan objective evidence. Influencedby these arguments,the Chiefsof Staff(COS) concluded on May 25, 1940,thatGermany mightbe beaten by economic pressure, the bombing of economic and psychological targets,and the instigationof popular revoltin German-occupied territories.By late June, Churchillhad picked up on this thinking,arguing thatairpowerwould cause Hitler"possibly decisive difficulties" in Germany and other areas he had to feed and defend.82On July8 he asserted: "There is one thing that will bring him back and bring him down and that is an absolutely devastating, exterminatingattack by very heavy bombers from the RAF. This thesis seems plausible with hindsightbecause it reflectswhat actually resulted. Yet directevidence to support it is sparse. In addition, as FrederickM. Sallagar, The Road to TotalWar(New York: Van Nostrand Reinhold Co., 1969), pp. 181-182, has noted, the decision was made at a time, August 24, when FighterCommand was not in terribleshape as it would be two weeks later. 80.

His opinion of the utilityof bombing had evolved froma pre-warhistoryof opposition to, and lack of faithin, the independent strategicair offensiveaimed at morale.84 In May when he became prime minister,Churchillwas particularlyexposed to the organizationallobbyingon the few air plans available. Perhaps more important,the situation and RAF culture constrainedthe options available to Churchill: Britainwas most prepared to strikeout at Germany through strategicbombing.85Given the RAF's militaryadvice, the interpretationof events, and the limited capabilities available (strategic area bombing), Churchill's choice of strategicbombing is largely explained by a cultural perspective. Without the RAF's bomber culture,Churchillmightwell have shared Hitler's dispositionagainst unrestrictedair operations.The difference in the compatibilityof each side's air forceculture with strategicbombing explains why Britainand Germanyhad opposite responses to incidentsthat violated restrictionson the use of aerial force.

At the end of World War I, Churchill doubted that victorycould be had by terrorizing civilians. Webster and Frankland, The StrategicAir Offensive, p. 47. In the 1930s, Churchill advocated air defenses as a means of mitigatingair attacks. He did not believe the "bomber would always get through." See Winston S. Churchill,The Gathering Storm(Boston: Houghton MifflinCo., 1948), pp. 147-152; Tress, BritishStrategicBombing,pp. 69-70. In September 1939, citingthe results of the Spanish Civil War, Churchilldoubted that "the essential elements of war" would be changed by the air arm. On May 7, 1940, Churchillhad opposed unrestricted bombingbecause of Britain'sperceived inferiority to Germanyin air power. See W.M. (40) 114, Conclusions, Minute 1, May 7, 1940, CAB 65/13,PRO. AfterSeptember 1940, Churchillvaried between doubt and support for the air offensive.See Maxwell Philip Schoenfeld, The War MinistryofWinstonChurchill(Ames, Iowa: Iowa State UniversityPress, 1972), pp. 92-101. 85. But Britain'sair power resources could also have been used to attack Germany's invasion effortor help with the battle at sea. See Tress, BritishStrategicBombingPolicy,pp. 215-220.

Security18:4 1132 International was discussed at many of the negotiationsof thatera. But only one treatythe Geneva Protocol of 1925 prohibitingfirstuse of chemicalweapons-was signed. At the beginning of World War II, Britainand Germanyexchanged pledges reaffirmingtheir no-first-usecommitments.Despite these agreements, nations expected CW use and went to considerableeffortspreparing for such combat. CW was widely recognized by all participantsin World War II to have significantmilitaryutility.86However, throughoutthe war, even though a range of CW accidents occurred,theynever led to escalation. The friction,traditionalorganization, and securitydilemma perspectives all would predicta spiral of use fromrestrictedweapons even ifby accident. Intense conflict,complex operations, and great uncertaintycharacterized many of the situationswhere CW incidentsoccurred. These sources of friction helped cause accidents, but did not cause escalation. All of the military organizationsinvolved also had plans, troops,and weapons forCW use but, contraryto traditionalorganization theory,theirroutines did not generate escalation. According to the securitydilemma argument,both sides should have feltinsecure due to the surprise-attackadvantage of CW, should have been poised to strikeback to minimizedisadvantage, and should have been leery of any type of trustin enemy restraint.It was widely acknowledged thatgas was most effectively used in a surpriseattack. For example, General Ochsner, the head of German CW in World War II, argued that where attackerand defenderare equally well prepared, the attackerhas the advantage because of abilityto completepreparations,achieve surprise,and choose 86. This is evident in the analysis and calculations of individual countriesand outside experts. For example, in Britaina 1939 review of gas requirementsconcluded that "with added and improved weapons chemical troops will be used in a futurewar more than they were in the last." See "Gases for Use in the Field and the Quantity of Each Required," prepared by the Directorof MilitaryTrainingand Directorof StaffStudies by request of the Intra-serviceCommitteeon Anglo-FrenchChemical WarfareConversations,July7, 1939,War Office193/740,PRO. From December 1939 tests, the Britishconcluded that, "we have at our disposal a potential weapon of great value." See "Chemical Warfare-High Spray Trials," fromMO1 to DDMO, January30, 1940, WO 193/726,PRO. Militaryintellectualssuch as B.H. Liddell Hart and J.F.C. Fuller were also proponents of CW. 87. Gas was not, however, a use-it-or-lose-it weapon, nor was CW just an "offensive"weapon. It could be used forboth offenseand defense. Generallyitwas seen as benefitingthose interested in inhibitingfast moving operations afterit had been introduced to the battlefield.But initial use could facilitatean offensiveby opening wide gaps in enemy lines, as was the case with Germany's firstuse of CW in World War I. Britishplanners in World War II argued that CW might be effectivein breaking through enemy lines if the offensivetowards Germany were stalled in Italy or France.

Escalation1133 MilitaryCultureand Inadvertent the time, place and scale of attack. The defenderwould be hard pressed to keep defenses ready and would have to fightunder the most unfavorable conditions.88Inadvertent escalation would seem likely in these circumstances. However, the historyof incidents involving chemical warfare in WorldWar II-that is, its non-use-challenges thisnotion.The organizational cultureapproach argues that both Germanyand Britainhad "ways of war" thatworked to suppress inadvertentescalation. Indeed, thatis what we find. BRITAIN AND THE ABSENCE OF CW INADVERTENCE. Of the armed forcesof Britainaffiliatedwith chemical warfare,none found it a desirable weapon, and organizationalroutines forits use were not accorded the attentionand fundingotherareas received. Given theirprevailingorthodoxyof war-fighting, this is not surprising.In the Army,chemicalwarfaredevelopment was relativelyignored forthreereasons. First,the legacy of gas use in WorldWar I had alienated mainstreamofficersto this formof warfare.They did not like the interferenceof civilian chemists, the special privilegesaccorded to the companies that were tasked to wage CW, and the way thatgas complicated the traditionalbattlefield.Second, the Army's conservativeapproach to innovation worked against the acceptance of chemical weapons. The Army was but a loose collectionof traditionalregiments,like sportsor social clubs, thatsoldiersrelishedas a refugefromsocial and technologicalchange. Within this system,the technicalor mechanical officerwas looked down upon. Gas was a technical weapon. The Director of Artillerywas left in charge of chemicalwarfare,yet artillerymenseemed more concernedwith theirhorses than with their technical equipment. Finally,the Army had few resources and no central war scenario. This inhibited development of weapons like CW that were affectedby the specificgeographical and climatologicalconditions of the area in which theywould be used.89 88. Lt.

See CID, "Chemical WarfarePolicy," November 1924, p. 15, WO 188/144,PRO. International Security18:4 1134 RAF thinkingwas more compatiblewith gas use yetCW developmentwas in the hands of the Army and it received littleattentionor advocacy in the Air Ministry.The RAF recognized a potential role for CW, but when it appeared that CW development would reduce fundingformore preferred tools, such as bombing with high explosives and incendiaries,the RAF was willing to forgo the option.90The individuals that did advocate CW were censured by higherauthorities.9'In wartime,and specificallyin the decisions of 1944, the COS, led by the RAF, did not want theirhigh-explosiveand incendiarybombing loads cut in favorof gas. The former,theyargued, were well-triedand known to be effective.Although the bomber offensivewas not workingas intended, the blinders of RAF cultureinhibitedBritainfrom seeing this.92 This culturalaversion to CW was reflectedin the Britishmilitary'sstrong interestin avoiding its use. This is a dynamic unanticipatedby traditional organizational theory,which expects that militariesin war tend to foster escalation.93Yet in several instances, incidents that could have led to CW escalation were ignored or purposefullysuppressed. The firstwas in late 1940 when the War Officereceived reportsfromthe Middle East that Italy was preparing to use gas in Ethiopia. The Commander-in-Chiefof Middle East Forces suggested that a threatof retaliationin kind be made to deterit. The War Officequashed the suggestion,fearingthatgivingattentionto cases of possible use withoutactuallyretaliating(therewas doubt Britaincould or would) mightindicate to Germany that the UK feared a gas war, and thus encourage the Nazis to use it. It was decided thatshould the Italians employ 90. Also see CID, "The Manufactureof Toxic Gas forUse in War," Memorandum by the War Office and Air Staff,July 26, 1938, CAB 4/28, PRO.

For a similarassessment during the war, see CAS to the COS, "Chemical Warfare,"November 14, 1941, WO 193/711,PRO. 91. In 1942, Hugh Dowding, CINC of FighterCommand, wrote in a draftof an article that "mustard gas should be used in an air attackon Germany."But this view was not approved by the COS and he had to delete it. This was noted in a letterfromDowding to Basil Liddell-Hart. See B.H. Reid, "Gas Warfare:The Perils of Prediction,"in David Carlton and Carlo Schaerf, eds., ReassessingArmsControl(London: Macmillan, 1984), p. 153. 92. See F.H.

This is particularlytrue in formsof warfarethatalready have well-developed routinesand thatare non-innovative.CW fitboth of these categories.Britainhad prepared to use it and had already done so extensivelyin World War I; thus its use was not innovative.In fact,of the three means of warfare,strategicbombing was the most radical change fromconflictin World War I. MilitaryCultureand Inadvertent Escalation| 135 gas, the whole matterwould be swept under the rug: "Publicityshould not (repeat not) be given to the fact."94 The same phenomenon happened in 1942 with respectto reportsfromthe Far East that leftlittledoubt that Japan was using gas in China. The Army thoughtthatit was best to ignore this use since any Britishretaliationmight lead to unrestrictedJapanese CW in India, an area that was considered vulnerableto gas attacks.95This was a strategiccalculation,but one thatwas definedby a culturehostileto CW use. For even when strategiccircumstances changed, when India was not at riskin 1944, the COS stillrefusedto accept the evidence that the Japanese had used gas.96 In another example, when the Soviets became worried in the winter of 1942 that the Germans were readying to unleash a gas war, Stalin asked Churchillforhelp. This was given in the formof a pledge: If the Germans used CW against the Russians, the Allies would use CW against the Nazis. This idea threw the Britishmilitaryinto frenzy.The COS feltthe promise mightlead to immediate chemical warfare.Many were especially upset because the United Kingdom had no means to verifywhetherSoviet claims of German use were actually true.97 A final incident occurred during the German bombing of Bari Harbor in Italyin December 1943. One of the Luftwaffebombs hit a U.S. supply ship, the S.S. JohnHarvey,that was carrying2,000 100-lb. mustard bombs to be used in case CW escalated. The gas was released into the harborwhere many sailors ended up in the water during the raid. Clouds of the toxic agent driftedover the town. Some 1,000 civilians, as well as soldiers, were killed at Bari, many fromthe contaminatedwater and air. In contrastto Britain's reactionto the accidental bombing of London, the Allies did not propagandize the event or use it as an excuse forretaliation,but instead covered it up. Medical reportsof wounds were allowed to describe chemical weapon injuries only in general terms, and strictcensorship was institutedat all militarybases. When it was clear that the accident could not be kept secret, the Combined Chiefs of Staffprepared a statementwhich reiteratedthat "Allied policy is not (repeat not) to use gas unless or until the enemy does 94.

German military GERMANY AND THE LACK OF INADVERTENT culturewas no more favorable to gas than was Britain'sand the effectof unintended incidents on escalation was the same: restraintendured. Dating back to Moltke, German militarythought focused on fast, decisive maneuver and encirclementas a means of victory.In World War I, a skepticalmilitarywas convinced to trygas based on the argumentthatit would break the stalemate of trenchwarfare.99It did not. In fact it turned out to be a poor fitwith Germany's desired operations in World War I because it inhibitedmobility and impeded the aggressiveness of soldiers. In addition it led to civilian interferencein militaryaffairs,particularlyby officiallysanctioned chemists.'00 German doctrineon the eve of WorldWar II was decidedly offensive:fastmoving and long-rangearmored and motorized units would spearhead the attack,break throughthe enemy's front,penetratequicklyand deeply into the rear, counter enemy effortsto block encirclementor escape, and sever communications,supply, and command lines. Infantrydivisionswould then move in for annihilationbattle fromthe front.Chemical weapons, which were cumbersome, could play only a limited role in such a strategy.CW equipment and munitionswould jam supply lines, and chemical casualties were difficultto handle: they did not die easily and needed intensivecare. This was particularlytrue since the use of gas in offensiveoperationswould have demanded centralized control which clashed with the decentralized German auftragstaktik system.'0' For reasons that differfromBritain's-Germany's later defensive stance, the threatto its survival, and the mercurialnature of Hitler,who ignored many norms of state behavior-it may seem surprisingthat the Reich did 98.

Escalation1137 MilitaryCultureand Inadvertent not reflexivelylapse into CW use. Coupled with securitydilemma considerations,such as surprise-useadvantages, it is even more curious why there was no accidental escalation. Yet froma militarycultureperspective,the lack of escalation is not a puzzle. During Germany'sinvasion of Poland, mustardgas was used in the Polish defenseoftheJaslobridge,resultingin several Germancasualties and deaths. Instead of responding in kind, however, the Third Reich's militaryassumed that the Polish Supreme Command had not ordered the use of gas. They were right,but the choice seemed more a product of hopeful expectation than shrewd analysis.'02The benign assumption that the Germans made in this situation,that the gas use was not intentional,contrastssharply with what Britain concluded about the Luftwafferaid on London, or Lemp's judgment on the status of the Athenia.When the German Foreign Ministry wanted to use the incident for propaganda, General Halder was quick to squelch the idea. It appears thathe, like his Britishcounterparts,was afraid it mightlead to the initiationof CW.103 A second incidentin July1941 testifiesto the unusual effortssome states went to in hopes of avoiding escalation in certainareas. The Soviet Union claimed that Germany was gettingready to use chemical weapons. This accusation was based on the capture of a German manual on the offensive use of gas. In response, Germanywas quick to announce throughits official news agency that the manual was merelya trainingguide, allowed by the Geneva Protocol,and not an imminentplan.'04That same summer,German militaryleaders had received fivereportsfromthe fieldthatthe Soviets had used chemical weapons. One involved a bomber,two were artilleryattacks and two were armored vehicle assaults. The Germans decided that not enough "objective" evidence existed thatthe attackshad occurred.But since twelve German soldiers had mustard gas wounds, it was conceded that perhaps a single gas bomb had been dropped. Otherwise, however, the incidentwas ignored.'05 102. Ochsner states that this findingwas "a great reliefto us." Ochsner, TheHistoryofGerman CW, p. 16. 103.

See Armeeoberkommandd11 an Oberkommando des Heeres, July1, 1941, RW 5/v.346, BA-MA, for a list and descriptionof the injured soldiers. For the analysis of the incidents see International Security18:4 1138 Another provocativeaccident occurredduring the Allied invasion of Italy at Anzio in 1943. A German shell struckan Allied weapons depot containing chemical munitions. The explosion released a cloud of gas that driftedtowards the German lines. The Allied commander was quick to notifyhis German counterpartthat this release of gas was strictlyinadvertent.The German officeraccepted the explanation despite his disadvantage had the Allied officerbeen lying.'06 Even at the end of the war, when the Germans faced imminentpolitical extinctionand the Allies feareddesperate escalation, therewas no last resort to CW in the confusing, threatening,frenzied disintegrationof the Third Reich. In fact, Germany became particularlycautious about unauthorized use. Supplies were ordered moved, not destroyed,so as to avoid any event that might give the enemy a pretextfor CW use.'07 Chemical stocks and factorieswere given top priorityin the allocation of scarce transportspace. Despite precautions, on April 18, 1945, an accident at a chemical depot in centralGermany led to the contaminationof the surroundingtwentykilometers. The Wehrmachtanticipated that the enemy mightpoint to such an incidentas an excuse forinitiatingdeliberateuse of CW and it recommended haltingthe riskytransferof chemical stocksand givingthe Allies the location of the sites. Hitlervetoed this order.'08Nonetheless, therewas no escalation. ORGANIZATIONAL CULTURE AND INADVERTENCE Variationsin inadvertentescalation in World War II are explained betterby organizational culture than other prominentimages of escalation. The significantinfluence of culture is summarized in Table 1. There are two key facetsof the link between organizationalcultureand inadvertence.The first im Ausland Nr. 10," August 12, 1941, RH 11 IV/v. "Mitteilungenuber Gaskriegsvorbereitungen 17, BA-MA. 106.

Clausewitz tells us that accidents are unpredictableand unavoidable in the complexityof war. The incidentsreviewed above do seem to have multiple causes and do not fitneatly under any one theoryexcept the vastly generalized and residual one of friction.Nonetheless, some accidentsmay fitmore of a patternthan would be suggested by a random-walkthesis. Some degree of regularitymatches organizations to accidents, as Graham Allison suggested in EssenceofDecision.'09But the thrustofAllison's argument-and that of otherswho have employed traditionalorganization-theory logic-assumes that,in gross terms,similarorganizationsact in similarways. According to thislogic we should expect militarieswith the same structuresand functions to incurthe same types of incidents.But this emphasis on structureneglects the importanceofbeliefsand norms.As was demonstratedby the differences between the accidents of German and Britishsubmarines,similarstructures and functionsdid not produce the same type ofresults.The submarineforces of both navies were prepared to targetand destroy enemy ships. But the BritishNavy saw only a role for hittingwarships, whereas the German 109. E.g., Allison, EssenceofDecision,pp. 139-140. Where frictionwas comparable-for example in the Britishand German submarine situations-an accident occurred in one, but not in the other. And even where frictionis expected to be most decisive-where warfareis complex, fightingintense, and informationuncertain-accidents did not cause escalation. This was apparentin the restraintthatenduted in CW duringthe fiercebattleson the continentin the latter stages of WWII. Security18:4 1140 International Navy considered anti-tradeattacksas a centralformof warfare.A focus on this divergence in the hierarchyof beliefs in militaryorganizations more accuratelyaccounts for what occurred. The role of culture is more important-and the influenceof the armed forcesmore varied in thattheycan also inhibitaccidents, than is recognized by friction,the securitydilemma, or a traditionalorganizationviewpoint. The second, and more important,tie between organizationalcultureand accidents concerns the impact of the unintended incidents that do occur. Avoiding accidents altogethermay be an impossible task. But as we have seen, some accidents lead to escalation, while othersdo not. Contraryto the expectationsof the traditionalorganizationalschool, militariesdo not always push events towards escalation,even afterhostilitieshave begun. Depending on culture, militaryorganizations may act as inhibitorsor as advocates of escalation. The armed forces play a centralrole in war throughthe development of capabilities, planning, informationprocessing, operational response, and judging militaryutility,and theirculturestherebyhave a decisive impact on national choices. Where specificmeans of warfareare compatible with one side's organizational culture,accidental use of a taboo means of warfareby the enemy oftenleads to escalation. Militariesand states in such situationsare likelyto emphasize the antagonisticrole the otherside played, encourage propagandisticuse of the incident,and stressthe militaryadvantage in theirown escalation. Such tendencies increase the likelihood of inadvertentescalation, as was evident in German submarinewarfareand Britain's bombing of Berlin. In contrast,when a type of warfareis antitheticalto organizationalculture, restraintendures in the face of provocative enemy incidents. Information encouragingescalation is suppressed, enemy actions are taken on faithto be accidents, effortsare made to communicategood will to the opposing side, and internalproposals to seize propaganda advantages are rejected. These dynamics were evident in German strategicbombing, and Britishand German decisions related to chemical warfare. As we have seen, escalation windows are inevitablythrown open in the midst of conflictby the unintended and often unpredictable incidents that occur in "unthinkable" restrictedmeans of warfare.But whetherstates jump throughthose windows seems to be importantlyaffectedby militaryculture. Escalation1141 MilitaryCultureand Inadvertent Inadvertence Contemporary Some of the taboos of the inter-warperiod remain intactto varyingdegrees today. Chemical and biological warfarecontinue to be stigmatized,and so too is strategicbombing,as seen in the allied efforts to avoid civiliancasualties in the Gulf War. The most strikingdistinctionbetween the period examined above and the modern age is the immensely destructiveforce of nuclear weapons."0I Some believe thatany serious armed clash between major power antagonists would be likely to result in nuclear use. Some assume that an accidental event involving a nuclear weapon, particularlyin the midst of war, would lead to a widespread exchange.111 What the organizationalculture approach suggests, however, is that this need not be the case. Depending on organizationalpredilection,some incidentsare likelyto lead to escalation while others will not. Thus fornational leaders, the abilityto controlescalation involves understandingand managing bureaucraticculture. This is a differentsortof enterprisethan those suggested in otherrecentstudies. It is not about the technicalspecificationsand procedures of command and control systems.112 Nor is it about the formalstructuraltraitsof organizations themselves.113 Furthermore,the primaryfocus is not on the explicitnature of civil-military relations and the problem of gettingsoldiers to adhere to the orders and aims of the higher militaryor civilianleadership, although that is certainlya concern.114 Rather, the policy task is first,to understand the norms and beliefs of militaryservices on war-fightingthat permeate the plans, capabilities, and 110. It is unlikelythat these powerful tools of violence have neutralized the dynamics of the images of inadvertencediscussed here. Friction,the securitydilemma, and organizationaldynamics have all figuredprominentlyin research on the nuclear age; e.g., BarryPosen uses all threein his study Inadvertent Escalation. 111. This is the predominantthrustof traditionalorganizationtheory,"friction,"and "normal accident" theorists,along with most who study nuclear accidents. See Bracken, "Accidental Nuclear War," in Graham T. Allison, Albert Carnesale, and Joseph S. Nye, Jr.,eds., Hawks, Doves, and Owls: An AgendaforAvoidingNuclearWar (New York: W.W. Norton, 1985), pp. 3749; and Sagan, The Limitsof Safety,pp. 250-51, 259-264. For an argument that rejects this thinking,see JohnMueller,Retreat fromDoomsday:TheObsolescence ofMajor War(New York:Basic Books, 1989), pp. 237-238. 112. E.g., Blair,The LogicofAccidentalNuclearWar. 113. Although they acknowledge the role of culture,this is the focus of the "high reliability" theoristsdiscussed in Sagan, The LimitsofSafety,pp. 14-28. 114. On control of U.S. nuclear weapons, this issue is covered thoroughlyby Peter Douglas Feaver, Guardingthe Guardians:CivilianControlof NuclearWeaponsin the UnitedStates (Ithaca: Cornell UniversityPress, 1992). International Security18:4 1142 skills available to keep the peace. Secondly, it is to shape that culture, if necessary, so that it is compatible with national objectives. These tasks are far from simple. Professional militarycultures formin a society set apart fromthe broadernation theyserve, and such organizationshave no domestic competitorsto ensure that the consumer (i.e., national interest) is wellserved. Even in the United States, where there is a traditionof civilian oversightand "independent" bodies to contributeto militarythinking,outsiders (especially those who spend fouryears in Washingtonand then move on) sometimes have problems gaining obedience to explicitdirectives,let alone the abilityto affectorganizational culture.115Nonetheless, there is a need foralternativeparties-probably civilianexpertsauthorizedby the highest levels of government-to review operational plans.116 This is not about who has the final say in using force:that is clearlythe politicalleadership. Instead, the issue is how choice is subtly,but powerfully,circumscribedby the pre-existingorganizationalmind-set,withits attendantcapabilities,skills, and intelligence,that dominates operationalthinking.Thus, the centraltask is to explicate and assess the assumptions and beliefs that shape the way that militariesthinkabout practicalwar-fighting in termsboth of theirown efficacyand of politicalobjectives. The aim of such an effortwould not be to de-professionalizeor to politicize America's competent armed forces.117Nor is it to blame soldiers fordoing an inadequate job. Militaries cannot be considered the cause of war, nor should they be pictured as an unwavering source of escalation. The armed forcescan act as a friendof restraintas well as a foe (and eitherrole might serve a national purpose). Nonetheless, the pervasive influenceof military cultureon inadvertencesuggests the need to improve understandingof the beliefsand norms that characterizethese organizations.It is certainlyin the nationalinterest,and to the benefitofinternationalsecurity,thatwar-fighting culturesbe compatiblewith higherlevel politicalstrategyand goals. 115. A range of anecdotes and analysis on this topic are found in JanneE. Nolan, Guardiansof theArsenal:The PoliticsofNuclearStrategy(New York: Basic Books, 1989), pp. 5-6, 31-32, 248285; and Feaver, GuardingtheGuardians,pp. 227-229, 232-234, 242-244. 116. Posen, Inadvertent Escalation,p. 217, offerssome good proposals along these lines. 117. The dangers of doing so have been articulatedin the classic workby Samuel P. Huntington, The Soldierand the State: The Theoryand Politicsof Civil-Military Relations(Cambridge, Mass.: Harvard UniversityPress, 1957).
