This article sketches out the nature of legal responses to humanitarian
intervention in general and the Kosovo intervention in particular, with
particular attention given to arguments that were not made. Though
some possible arguments appear to have been omitted through oversight, the nature of the discussion suggests a view of international law
as one policy justification among others. These debates are then situated in a broader historical context by drawing parallels between the
current international framework and earlier historical periods in which
no body comparable to the Security Council existed. It is argued that
developments since the end of the Cold War, and in the past few years
in particular, suggest a reversion to pre-Charter paradigms, where the
council exists merely to advise member-states and international order
is contingent, once more, on the goodwill of the powerful. The reluctance of the Great Powers to submit themselves to law may yet have a
more lasting effect on the international order than NATO’s decision to
wage war on behalf of the Kosovo Albanians.
Introduction
I
N DEBATES THAT HAVE EXERCISED the many humanitarian intervention agonists since NATO’s Kosovo intervention in 1999, the currency of
international law has been of uncertain value. While the bombs were falling,
many international lawyers sought cover under references to the inadequacy
of ‘traditional’ international law; few were willing to condemn NATO for taking action against a brutal leader who clearly wished ill on the Albanian population of Kosovo.1 Though academic commentators tended, with hindsight, to
become more polarized on the question, the more sober assessments by the
acting states themselves have continued to blur the question of legality. In a
report on the intervention, the United Kingdom Foreign and Commonwealth
Office concluded that, ‘at the very least, the doctrine of humanitarian intervenSecurity Dialogue © 2002 PRIO.

tion has a tenuous basis in current international customary law, and ... this
renders NATO action legally questionable’.2 In proceedings before the International Court of Justice, only Belgium sought to establish that its participation
in the NATO airstrikes did not violate Article 2(4) of the UN Charter, which
prohibits the threat or use of force.3 Other states emphasized the relevance of
Security Council resolutions (which fell well short of authorizing the use of
force) or made reference to the existence of a ‘humanitarian catastrophe’ – apparently wary of invoking the doctrine of humanitarian intervention by
name.4
Such reticence to reach a firm position on the legality of the intervention was
not restricted to the states participating in it. Two well-respected independent
commissions also returned Solomonic verdicts. The Kosovo Commission,
headed by Richard Goldstone, concluded that NATO’s intervention was ‘illegal but legitimate’.5 The International Commission on Intervention and State
Sovereignty, chaired by Gareth Evans and Mohamed Sahnoun, took a more
political tack. Acknowledging that, as a matter of ‘political reality’, it would be
impossible to find consensus around any set of proposals for military intervention that allowed for intervention not authorized by the Security Council
or the General Assembly, the commission sought to present this as a political
rather than legal problem:
That may still leave circumstances when the Security Council fails to discharge what this
Commission would regard as its responsibility to protect, in a conscience-shocking situation
crying out for action. It is a real question in these circumstances where lies the most harm: in
the damage to international order if the Security Council is bypassed or in the damage to
that order if human beings are slaughtered while the Security Council stands by.6
This article will not seek to explore the legality of unilateral humanitarian intervention as such; this has been undertaken elsewhere, with varying degrees
of success. Rather, the focus here is on the question of whether and how international law matters at all in this area. Of central interest is the decision on the
part of key actors to avoid a clear legal determination of the issues at stake:
this article will examine that question in the context of the preceding decade of
increased activism under the auspices of the United Nations, and explore
what structural consequences the dilution of legal standards might have for
the role of law in the current international order.7
First, the nature of legal responses to humanitarian intervention in general
and the Kosovo intervention in particular will be sketched out, with particular
attention given to arguments that were not made. This will then be situated in
a broader historical context by drawing parallels between the current international framework and earlier historical periods in which no body comparable
to the Security Council existed. In essence, it will be argued that developments
since the end of the Cold War, and in the past few years in particular, suggest
a reversion to pre-Charter paradigms, where the council exists merely to advise

member-states and international order is contingent, once more, on the goodwill of the powerful.
International Law and the Kosovo Intervention
Most legal analysis of NATO’s Kosovo intervention considers the provenance
and future of Article 2(4) of the UN Charter. The passage agreed to by states at
the San Francisco conference of 1945 was broad in its scope:
All Members shall refrain in their international relations from the threat or use of force
against the territorial integrity or political independence of any state, or in any other
manner inconsistent with the Purposes of the United Nations.8
The prohibition was tempered by only two exceptions. First, the Charter preserved the ‘inherent right of individual or collective self-defense’.9 Second, the
newly established Security Council was granted the power to authorize enforcement actions under Chapter VII. (Although this latter species of military
action is sometimes considered in the same breath as unilateral humanitarian
intervention, council authorization changes the legal questions to which such
action gives rise.)10 Most serious legal analysis of the alleged ‘right’ of humanitarian intervention seeks to justify it either (1) within the terms of Article 2(4),
by reference to a parallel rule of customary international law, or (2) within a
broad interpretation of Security Council resolutions not explicitly authorizing
the use of force – especially where it is alleged that a properly authorizing
resolution is blocked only by capricious use of the veto.11
A further possible exception concerns the role of the General Assembly.
Interestingly, the role of the General Assembly in authorizing intervention
was first raised at a time when it was feared that a Russian veto would block a
council resolution authorizing military intervention. For some months in 1950,
the representative of the USSR boycotted the Security Council in protest at the
continuing recognition by the United Nations of the recently defeated Kuomintang
regime in China. In his absence, three council resolutions were passed that in
effect authorized the United States to lead a military operation against North
Korea under the UN flag. The return of the Soviet delegate precluded any further council involvement.12 At the initiative of Western states, the General Assembly adopted the ‘Uniting for Peace’ resolution. This provided that the assembly would meet to recommend collective measures in situations in which
the veto prevented the council from fulfilling its primary responsibility for the
maintenance of international peace and security. In the case of a breach of the
peace or act of aggression, the measures available were said to include the use
of armed force.13 The legal status of the capacity of the General Assembly to
do more than authorize peacekeeping is questionable,14 but a resolution was
296
Security Dialogue vol. 33, no. 3, September 2002
passed recommending that all states lend every assistance to the UN action in
Korea,15 and this capacity was used again in relation to the Suez crisis in 195616
and in Congo in 196017 – on these occasions against the interests of the Western powers that had developed the mechanism earlier in the decade.
In the course of the Kosovo crisis, especially when it appeared likely that
Russia would block any attempt to authorize the use of force against the Federal Republic of Yugoslavia (FRY), it might seem surprising that such a
mechanism was not considered. In fact, as shown in testimony by Professor
Adam Roberts before the UK Foreign Affairs Committee six months after the
conclusion of hostilities, the possibility of going to the General Assembly had
indeed been suggested when the first Rambouillet negotiations broke down.
His statement is worth quoting at length:
I actually raised that issue in a meeting at Chatham House on the day Rambouillet
initially failed, in February of 1999, and I suggested that might be one possible way out of
the Security Council’s obvious paralysis on the question of Kosovo. At that time, the
Foreign Office took the view that this was very ill advised, and I was told that really it
was not very helpful of me to have talked about this. Because I think they clearly took the
view (a) that it was uncertain that they would get anything like the two-thirds majority
which I believe is what is required under ‘Uniting for Peace’, and (b) that the General
Assembly is a somewhat cumbersome instrument, in that it does not meet continuously,
it cannot continuously develop its policy, once you have got an agreement in the General
Assembly you will be absolutely stuck with whatever that agreement is, and it is not the
kind of flexible instrument that the Security Council is.18
This is interesting because it shows two discrete reasons why fuller recourse
was not had to international law. On the one hand, there was reluctance to
submit important decisions to such a ‘cumbersome instrument’ as the UN
General Assembly; on the other, it was unclear whether this body would deliver the desired legitimacy anyway.
The political tension underlying such an approach to legal advice in the field
of foreign affairs is most evident in James Rubin’s account of debates between
the NATO capitals on the legality of proposed NATO action in the weeks
prior to the air campaign. A series of strained telephone calls between US
Secretary of State Madeleine Albright and UK Foreign Secretary Robin Cook
had led the latter to cite problems ‘with our lawyers’ over using force in the
absence of UN endorsement. Albright’s reply, reportedly, was, ‘Get new lawyers.’19
Equivocation about the role of international law in decisionmaking processes
is hardly new; the history of international law is to some extent a struggle to
raise law above the status of being merely one foreign policy justification
among others.20 In the course of the US operation to oust Manuel Noriega
from Panama in 1989, for example, Attorney General Richard Thornburgh was
first called in to advise President George Bush that the United States had clear
legal authority to act on 19 December 1989 – two days after Bush had authorized the operation and a matter of hours before 24,000 marines actually landed
Simon Chesterman Legality Versus Legitimacy
297
in Panama.21 Legal advisers today appear to have greater involvement in some
decisions – especially on questions of targeting high-precision weapons – but
on fundamental questions of whether and when to use force, they are commonly marginalized. To a non-lawyer, this might seem a trivial or obvious
point. But it is instructive to compare current debates over the legal regulation
of the use of force with debates that pre-dated the UN Charter; indeed, much
about recent practice suggests that analogies with times when the use of force
itself was not prohibited are particularly appropriate.
Humanitarian Intervention Before the United Nations
There is a widespread misconception that, before Article 2(4) of the UN Charter outlawed the use of force,22 a right of humanitarian intervention was recognized in customary international law. Quite apart from the circumstances in
which this alleged 19th-century right was usually invoked – generally in support of Christian brethren against their Muslim overlords or neighbors – it is
misleading to suggest that a majority of legal scholars supported the view that
humanitarian intervention existed as an exception to the general prohibition
on intervention.23
Such intellectual history is complicated by the fact that international law did
not proscribe unilateral resort to war as a means of settling disputes between
states until the 20th century.24 The term ‘intervention’ came into use over the
course of the 19th century, but its meaning remained imprecise. In any event,
in the absence of a clear distinction between intervention and war, any regulation of the former could be circumvented by resort to the latter. When the
United States objected to a pacific blockade by Great Britain and Germany
against Venezuela in 1902, for example, the European powers simply acknowledged a state of war to exist.25
Interestingly, debate at the time exhibited divisions comparable to that seen
now among legal scholars, with some confidently asserting a right of humanitarian intervention26 and others confidently rejecting it.27 Of most interest here
is the significant body of writers who held that international law could
or should have little to say about the matter at all. Historicus (Sir William
Harcourt) expressed this in a frequently quoted passage published in 1863:
Intervention is a question rather of policy than of law. It is above and beyond the domain
of law, and when wisely and equitably handled by those who have the power to give effect to it, may be the highest policy of justice and humanity.28
Various writers echoed his view that international law had little to say about
such ‘high politics’.29 Others adopted a more subtle position, noting that there
is scope for moral evaluation of state behavior independent of the legal regime.
298
Security Dialogue vol. 33, no. 3, September 2002
The jurist William Edward Hall explained the apparent political and juristic
acceptance of humanitarian intervention as reflecting ‘considerations of sentiment to the exclusion of law’.30 His own position was that no such intervention is legal unless ‘the whole body of civilized states have concurred in
authorising it’.31 Where such authorization is not possible, he argued that such
measures should be justified
as measures which, being confessedly illegal in themselves, could only be excused in rare
and extreme cases in consideration of the unquestionably extraordinary character of the
facts causing them, and of the evident purity of the motives and conduct of the intervening state. The record of the last hundred years might not have been much cleaner than it
is; but evil-doing would have been at least sometimes compelled to show itself in its true
colours; it would have found more difficulty in clothing itself in a generous disguise; and
international law would in any case have been saved from complicity with it.32
Oppenheim, in a passage that remained unchanged through five editions of
his International Law, doubted whether there was a rule admitting ‘interventions in the interests of humanity’, but did note that ‘public opinion and the attitude of the Powers are in favour of such interventions’.33 He concluded that
such a right may be recognized at some point in the future, but restricted it to
collective intervention by the Great Powers.34
Most of the themes that dominate contemporary debates on humanitarian
intervention were present in these 19th- and early 20th-century texts: the
moral impetus to act on behalf of the oppressed and not to let evil go unpunished; concern about the possible abuse of any unilateral right of intervention
on subjectively determined grounds; the emerging public discourse on human
rights issues; and the countervailing desire to preserve sovereignty. Central to
these themes was the overriding view that international law could neither
sanction nor ignore actions that ‘shock the conscience of mankind’.35
But nor was there consensus on what it could do. Following the conclusion of
World War II and the adoption of the UN Charter, the use of force was outlawed and the Security Council was established and granted primary responsibility for international peace and security. It is almost certain that none of the
framers imagined the council authorizing military intervention solely to protect human rights of nationals within a sovereign state,36 but it was clearly intended to have a monopoly on the use of non-defensive force. Nevertheless,
there is no evidence that the framers turned their mind to what would happen
in the event that the system they were constructing simply failed to function.
Humanitarian Intervention and the Security Council
In one of the war crimes trials brought in the US Zone of Germany two years
after the conclusion of World War II, Brigadier General Telford Taylor, Chief
Simon Chesterman Legality Versus Legitimacy
299
of Counsel for the United States, was required to put forward a legal basis for
a charge of crimes against humanity. Taylor argued that the concept of crimes
against humanity first found articulation in the works of Hugo Grotius, whose
concept of the ‘just war’ allowed for armed intervention to put an end to inhumane atrocities against civilian populations; he cited a number of such
interventions from the 19th century. There could be no doubt, he stated, that
murderous persecutions and massacres of civilian population groups were
clearly contrary to the law of nations long before World War I. And, on occasion, nations had resorted to military intervention to put a stop to such atrocities.37 Nevertheless, he continued,
unilateral sanctions of this kind today are ineffective if confined to words and dangerous
if military measures are resorted to. Intervention may well have been an appropriate
sanction in the nineteenth century, when the fearful resources of modern warfare were
unknown, and particularly when resorted to by a strong nation in behalf of minorities
persecuted by a much weaker nation. Indeed, lacking some vehicle for true collective action, interventions were probably the only possible sanction. But they are outmoded, and
cannot be resorted to in these times either safely or effectively.38
As is well known, the intended ‘vehicle for true collective action’ – the Security Council – was soon paralyzed by the Cold War. The failure to implement
the collective security system as envisaged by the framers of the Charter is
well documented.39 In particular, agreements to place military forces at the
disposal of the Security Council were never completed.40 The Military Staff
Committee (MSC), which was to advise and assist the Security Council in the
‘employment and command of forces placed at its disposal’,41 today remains
little more than a curiosity. Its published records indicate that the MSC has
met every two weeks since February 1946; in over 50 years, it has done nothing of substance since it reported to the council in July 1948 that it was unable
to complete the mandate given to it two years previously. The fortnightly
meetings presently last a couple of minutes.42
Creative ways of getting around this paralysis were found. These included
use of the ‘Uniting for Peace’ resolution under the authority of the General
Assembly, discussed above, and peacekeeping (whose legal basis UN Secretary-General Dag Hammarskjöld famously located in Chapter ‘VI½’ of the
Charter).43 The most important mechanism for present purposes, however, is
the delegation of Security Council enforcement powers to one or more states
or a regional arrangement.
Council authorization started slowly: before the end of the Cold War, the
only isolated cases of authorized action were the Korean War and the blockade of southern Rhodesia. The decade following the end of the Cold War saw
an explosion in these actions. Since 1990, the council has explicitly authorized
one or more nominated states, regional organizations, or ‘coalitions of the
willing’ to use ‘all necessary means’ (or ‘all measures necessary’ or ‘all necessary measures’) in the following situations:

Operations Desert Shield and Desert Storm in Kuwait and Iraq (1990–91);
Operation Restore Hope (UNITAF) in Somalia (1992–93);
Opération Turquoise in southwest Rwanda (1994);
Operation Uphold Democracy in Haiti (1994–95);
Implementation Force (IFOR) and Stabilization Force (SFOR) in Bosnia
and Herzegovina (1995– );
a Canadian-led force in eastern Zaire (1996) (never implemented);
NATO-led Kosovo Force (KFOR) operations in Kosovo (1999– );
International Force in East Timor (INTERFET) (1999); and
International Security Assistance Force (ISAF) in Kabul and its surrounding areas (2001– ).
The council has also authorized more limited uses of force under Chapter VII
in the following situations:
•
•
UN Protection Force (UNPROFOR) and member-states providing air support in respect of safe areas in Bosnia and Herzegovina (1993–95); and
Operation Alba in Albania (1997).
In many cases, different classes of operations have been closely related to
one another, and have even overlapped. Peacekeeping operations in Somalia,
Haiti, Rwanda, and Bosnia were followed by enforcement operations when
they proved incapable of discharging their mandates. Similarly, enforcement
operations were followed by the deployment of peacekeepers in Somalia,
Haiti, and East Timor. In addition, the council has also given implicit retroactive approval to the Economic Community of West African States (ECOWAS)
Cease-Fire Monitoring Group (ECOMOG) operations in Liberia (1990–92) and
Sierra Leone (1997–98), and to operations by the Inter-African Mission to
Monitor the Implementation of the Bangui Agreements (MISAB) and France
in the Central African Republic (1997–98), as well as questionable authorization for the air-exclusion zone in Iraq (1991– ) and NATO threats and airstrikes in relation to FRY operations in Kosovo (1998–99). Most of these operations, with the exception of the action to drive Iraq from occupied Kuwait,
might be characterized as ‘humanitarian’ in character.
An irony of collective security in the 1990s is that just when it appeared that
the end of the Cold War would allow a more unified and active Security
Council to fulfill its primary responsibility for the maintenance of international peace and security, the same period saw a blurring of the circumstances
and the manner in which it could exercise that responsibility. Importantly, the
definition of a threat to international peace and security – the trigger for Security Council enforcement actions – underwent a remarkable transformation.
Amid euphoric talk of a ‘new world order’ after the expulsion of Iraq from
Kuwait, the council declared at a January 1992 summit that instability in the
economic, social, humanitarian, and ecological fields could also constitute
Simon Chesterman Legality Versus Legitimacy
301
threats falling within its purview.44 This followed actions in Iraq and former
Yugoslavia that appeared to relate primarily to internal strife; two years later,
after problematic operations in Somalia and Rwanda, the Security Council authorized an intervention to address the ‘threat’ posed by refugees and the obstruction of democratic rule in Haiti. By 1995, the International Criminal
Tribunal for the former Yugoslavia was able to assert that it was ‘settled practice’ that Chapter VII powers could be invoked to address purely internal
armed conflicts as a species of ‘threats to the peace’.45
At the same time, however, the absence of international institutions capable
of dealing with this increased responsibility led to a reliance on delegation.
Security Council enforcement actions were thus limited to situations where
acting states had the political will to bear the financial and human costs of
such measures. The UNITAF operation in Somalia confirmed this view in the
most graphic terms. Resolution 794 (1992) was not merely contingent on a US
offer of troops; the first draft was written in the Pentagon and tailored to US
Central Command (CENTCOM) concerns.46 In language that bordered on the
coy, paragraph 8 of the resolution referred to ‘the offer by a Member State described in the Secretary-General’s letter to the council of 29 November 1992’.47
A subsequent provision authorized the Secretary-General and member-states
concerned to ‘make the necessary arrangements for the unified command and
control of the forces involved, which will reflect the offer referred to in paragraph 8 above’.48 The effect was to hand over responsibility for the military
operation to the United States. A similar approach was adopted in Rwanda
(operation led by France), Haiti (by the United States), eastern Zaire (by
Canada, though never implemented), Albania (by Italy) and East Timor (by
Australia). Regional arrangements have also been authorized to intervene in
former Yugoslavia (NATO),49 Liberia and Sierra Leone (ECOWAS/ECOMOG),
and the Central African Republic (MISAB).50
These two themes – the plasticity of the council’s mandate and the contingency of council authorization on the willingness of a state or states to take action – were suggestive leitmotifs throughout the interventionist 1990s. Where
there was no willingness to act, the council remained silent. One of many possible illustrations of this point is the case of Sudan. Civil war has raged there
for almost two decades, with an estimated two million casualties.51 And yet
the only resolutions passed by the council in relation to Sudan concerned its
failure to extradite suspects in the unsuccessful attempt to assassinate President Mubarak of Egypt, which failure was determined to threaten international peace and security.52
This explicit conjunction of Security Council enforcement actions and national interest has exacerbated the politicization of council voting. To take the
best-known example, the United States offered various inducements to members of the Security Council voting on the resolution authorizing Operation
Desert Storm against Iraq. These included promises of financial help to
302
Security Dialogue vol. 33, no. 3, September 2002
Colombia, Côte d’Ivoire, Ethiopia, and Zaire, and agreements with the USSR
both to help keep Estonia, Latvia, and Lithuania out of the November 1990
Paris summit conference and to persuade Kuwait and Saudi Arabia to provide
the USSR with hard currency. China’s abstention appears to have been secured by agreements to lift trade sanctions in place since the June 1989
Tiananmen Square massacre and to support a World Bank loan of $114.3 million.53 Yemen, one of the two states to vote against the resolution, had $70 million in annual aid from the United States cut off.54 Minutes after the vote was
taken, a senior US diplomat reportedly told the Yemeni representative, ‘That
was the most expensive no vote you ever cast.’55 The other dissenting state,
Cuba, was already the subject of extensive sanctions.
Similar horse-trading has been documented in relation to the Security Council’s treatment of Haiti. David Malone writes that when an expanded mandate
to provide international support for the restoration of democracy was first
discussed in the council, Russia threatened to veto it owing to lack of US support for the language Russia had proposed in a separate resolution welcoming
a Commonwealth of Independent States (CIS) peacekeeping mission in Georgia.
He also suggests that Russia was disappointed that its support for France’s
Opération Turquoise had not paid more dividends.56
It would be idealistic in the extreme to argue that national interest should
not play a role in such actions. Unless the United Nations establishes its own
armed forces, it will remain dependent on national forces, which in turn are
dependent on domestic political support. The problem, rather, is that as authorization by the council has come to be seen as a formal step towards legitimate intervention, its substantive role in decisions on international peace and
security has diminished correspondingly. The general trend of Security Council delegated actions in the 1990s, then, was towards intervention only when
such action coincided with the preparedness of a regional power to act –
NATO in Europe, France and ECOWAS in West Africa, and the United States
in the Americas.57 Evidence of such a trend has been shown in the form of authorizations, but this has been accompanied by a more troubling shift in the
practice of the Security Council away from debating international peace and
security issues in open session to granting its formal imprimatur to prearranged deals. Such practices have depended on a level of political comity
that ultimately foundered when national interests clashed over the appropriate response to the situation in Kosovo in 1998–99.
International Law and the Great Powers
The League of Nations died, I remind you, when its members no longer resisted the use
of aggressive force.... We have witnessed tonight an effort to rewrite the Charter, to
Simon Chesterman Legality Versus Legitimacy
303
sanction the use of force in international relations when it suits one’s own purposes. This
approach can only lead to chaos and to the disintegration of the United Nations.
– US representative on the Security Council, 196158
At the beginning of the 1990s, the United States, while proclaiming itself the
victor of the Cold War, magnanimously asserted that this provided an opportunity for the United Nations to fulfill its long-promised role as the guardian
of international peace and security. The Security Council saw new possibilities
for action without the paralyzing veto; Secretary-General Boutros BoutrosGhali laid out grand plans with An Agenda for Peace.59 In President Bush’s
words, ‘the rule of law would supplant the rule of the jungle’.60
The rhetoric was euphoric, utopian, and short-lived. As quickly became
clear, international security issues continued to be resolved by reference to
Great Power interests; notably, the role of the UN Security Council was reduced to something akin to that of the League of Nations Council, with power
merely to give advice on matters of collective security.61 There is, now, a real
danger that the United Nations will be used only when it is geopolitically
convenient or useful to do so. The Security Council in particular may be reduced to what Richard Falk has described as a ‘law-laundering service’: a legitimizing mandate for the unilateral use of force or (at best) the use of force
by a coalition of like-minded states.62 This is suggestive of the earlier historical
period considered in this article, when peace was contingent on the alliances
of convenience that formed the Concert of Europe. In such a schema, the Secretary-General of the United Nations assumes the role of a sort of secular
pope, holding all influence and no power, ensconced in the bureaucracy of his
temporal office.63
These analogies are extreme, but highlight the diminishing significance of
the United Nations. Less than two months before NATO’s air campaign
against the FRY commenced, US Deputy Secretary of State Strobe Talbott gave
a speech that suggested one of the ways in which multilateralism was changing at the end of the 20th century. In what was, presumably, intended to be an
upbeat evaluation of multilateral approaches to dealing with the situation in
Kosovo, he praised the ‘unprecedented and promising degree of synergy’ that
had developed between ‘five bodies – NATO, the EU, the OSCE, the United
Nations and the Contact Group’, adding: ‘By that I mean that these disparate
but overlapping organizations have pooled their energies and strengths on
behalf of an urgent common cause.’64 In terms of the UN’s specific contribution, he noted that ‘the UN has lent its political and moral authority to the
Kosovo effort’.65 (No reference was made to the UN’s legal authority.) As
Bruno Simma has observed, the rhetorical point of placing the United Nations
in the company of regional organizations and similar institutions may suggest
(and be intended to suggest) that it should be regarded as existing on a similar
hierarchical plane as these bodies. Taken one step further, this could be seen
304
Security Dialogue vol. 33, no. 3, September 2002
as implicitly relativizing the legal primacy of the UN Charter and the obligations it embodies.66
Any such development should be treated with great caution. Despite the
reservations expressed here concerning the nature of UN authorizations to use
force, the decade of the 1990s was remarkable for the fact that recourse was
had to international institutions at all: the United States sought authorization
to intervene in the hemisphere previously demarcated as its own under the
Monroe Doctrine; France sought leave to intervene in its former African colonies; and Nigeria (belatedly) sought legitimacy for operations in its sphere of
influence. The politics might well have been the same as those that beset the
old world order, but they had assumed a very different form – it was the
abandonment of even this form that made Kosovo all the more dangerous a
precedent.
These concerns apply a fortiori in the wake of the terrorist attacks on New
York and Washington, DC, in September 2001. Though the United States
turned swiftly to the United Nations for support, obtained an extraordinary
resolution endorsing a broad exercise of its right of self-defense (including,
crucially, reference to states that ‘harbor’ alleged terrorists), and assembled a
wide coalition for its military action in Afghanistan, the fragility of the UN’s
position is exposed when one imagines what might have happened had that
support not been forthcoming. This became clear in the course of the USA’s
apparent vacillation in the first months of 2002 as to whether it would seek to
topple Iraqi President Saddam Hussein.
Conclusion
Writing on the development of the rule of law in 18th-century England, the
Marxist historian E. P. Thompson noted that the law certainly had the effect of
systematizing and reifying inequality between the classes. This was consistent
with the view of law as part of the superstructure of society in traditional (and
highly schematic) Marxism. But at the same time, he argued, it ‘mediated
these class relations through legal forms, which imposed, again and again, inhibitions upon the actions of the rulers’. For this reason, he termed the rule of
law an ‘unqualified human good’.67 Similarly, the position adopted here is that
the danger of an international rule of law being subverted to legitimizing the
interests of Great Powers is still preferable to the unregulated exercise of that
power. Even though Security Council resolutions authorizing interventions
might have been drafted in the war rooms of states preparing military action,
adopted in votes of questionable impartiality, and implemented by states of
dubious disinterestedness, such limitations do less damage to the international legal order than the abandonment of the multilateral institutions set in

place after World War II that characterized NATO’s 1999 intervention in former Yugoslavia.
