Why do powerful states often channel coercive policies through international organizations (IOs)? The article explains this phenomenon by theorizing the political advantages of working through a neutral institution, defined as one with heterogeneous and representative member preferences. The argument centers on the notion of strategic information transmission. IO involvement sends information about the coercer's intentions and the consequences of the coercive policy to foreign leaders and their publics, information that determines the level of international support offered to the coercing state. The logic helps explain why the United Nations Security Council plays a unique role in approving and disapproving the use of force. A case study of the 1990–91 Gulf War shows how these information transmission mechanisms work in practice and that the rationalist information argument provides more traction than a legitimacy-based alternative explanation.For valuable comments on earlier drafts, I would like to thank Charles Glaser, Peter Gourevitch, Lloyd Gruber, Darren Hawkins, Keith Krehbiel, David Lake, Charles Lipson, Daniel Nielson, Kenneth Schultz, Duncan Snidal, Michael Tierney, Daniel Verdier, Erik Voeten, and Joel Westra, as well as participants in the PIPES workshop at the University of Chicago and the conference on Delegation to International Organizations at the University of California, San Diego.

Why do powerful states channel coercive foreign policies through international organizations (IOs)? Governments that lack resources or expertise often require IO assistance for material and technical reasons, and weak states rely on international forums to increase their political clout and bargaining power. Powerful states, by contrast, typically do not need IOs to achieve specific objectives. On the contrary, because turning to an international institution complicates policymaking and entails some loss of autonomy, one might expect powerful states to avoid such entanglements. Yet even superpowers sometimes channel coercive actions, including the use of force, through IOs, despite viable alternatives that offer more flexibility and control—namely unilateralism and ad hoc multilateralism. The literature lacks a coherent explanation of the political logic for conducting coercion through IOs. Understanding this behavior has implications for important theoretical debates—engaging a range of rationalist and constructivist scholarship—over the role of formal institutions in international politics.
IOs have played a prominent if uneven role in statecraft since World War II. Even in the Cold War environment, the United States turned to the United Nations (UN) for the Korea intervention and sought cover from regional organizations to take action in Cuba, the Dominican Republic, Panama, and Grenada.1
The relevant bodies were the Organization of American States (OAS) in the first three cases and the Organization of East Caribbean States in Grenada. In the end, the OAS did not endorse the Panama intervention.
The Security Council has come to play a uniquely important role in this regard. Even in cases where the Council failed to endorse intervention policies, as in Kosovo in 1999 and Iraq in 2003, there was a concerted effort to gain such approval. Security Council enforcement powers have been employed with dramatically increased frequency—more than two hundred Chapter VII resolutions were passed between 1990 and 2004, compared to only seven during the Cold War—and its practice of authorizing coalitions of states to conduct coercive actions is well established and increasingly common.2
This is a conclusion of the so-called Brahimi Report, commissioned by the Secretary-General to study UN peacekeeping practices. UN Doc. A/55/305–S/2000/809, 21 August 2000. Most invocations of Chapter VII have come in the context of peacekeeping missions and do not qualify as coercive interventions. However, these operations are often complex and evolve toward a mixture of consent and coercion, sometimes with extensive authority to use force. See Fenton 2004; Roberts 2004, 136–39.

I shed light on this phenomenon by exploring the political advantages of conducting coercion through a formal, standing organization. Borrowing insights from the literature on delegation to domestic political institutions, especially U.S. congressional committees, I present a theoretical framework for explaining why and under what conditions states turn to IOs in the conduct of statecraft. I conceptualize IOs as agents of the international community (including both leaders and their publics) that serve to constrain and assess the policies of potential coercing states, thereby generating politically important information that can be used to screen desirable from undesirable actions. Under certain conditions, coercers have incentives to subject their actions to such scrutiny and limitations because doing so lowers the political costs of exercising power. The effect of IO involvement is especially important when the organization is more politically neutral, a function of the distribution of interests among the institution's members. A neutral IO is less likely to share the preferences of the coercer in terms of the means, timing, and goals of a policy and is more likely to be viewed as credible in the eyes of the international community. Coercing states face a tradeoff: as they turn to more neutral institutions, the constraints and the variance in outcomes increase but so do the political benefits.
My argument centers on the notion of strategic information transmission. When a coercing state works through a sufficiently neutral IO, this sends information to both foreign leaders and their publics, information that can determine the level of international support—material or political, direct or tacit—offered to the coercing government. Two processes, involving two types of information and two intended audiences, are key. First, the costs of channeling a policy through an IO allow the coercer to signal benign intentions vis-à-vis third-party states (that is, nontargets), a signal directed primarily at foreign leaders. In the context of coercion, especially by powerful states, these leaders feel threatened and are able to achieve some assurance and control through IO involvement. Second, the endorsement of a neutral IO sends policy-relevant information to foreign publics, who are “rationally ignorant”4
of international affairs and seek information shortcuts to determine the consequences of coercion and whether it is justified. This second audience can be as important as the first because leaders are often constrained by domestic politics from supporting another state's use of force. While the international relations (IR) field has considered the strategic role of domestic publics for coercing states,5See Fearon 1994; Schultz 2001; Mingst 2003.
Increased international support from these two audiences is desirable for a coercing state because it determines the political costs of a given policy and may affect its long-term success. The argument applies to any case of a powerful state—one that does not require logistical support or resources from an IO to achieve its objectives—conducting a policy of coercion. While my theoretical claims have relevance for the actions of any coercing state, limiting the analysis to powerful states has the advantage of helping to isolate political variables from simple issues of capacity. I confine my discussion to coercive military interventions (thereby excluding standard peacekeeping and purely humanitarian missions), although the argument theoretically speaks to economic and diplomatic coercion as well.
The phenomenon explored here has traditionally been explained in terms of the legitimacy conferred on a state's policy by IO approval, which leads to greater international support. Since Claude's influential article, countless scholars and policymakers have pointed to the legitimation function of IOs, especially the UN.6
However, while there is a virtual consensus that this legitimation effect matters, the term is used loosely, and there is no clear theoretical understanding of how it occurs. I provide a set of causal mechanisms in the rationalist tradition to help explain why IO approval increases international political support for state policies. I also offer an informational rationale for why states have coordinated around the Security Council as the primary institutional legitimizer of the use of force.7The article proceeds by briefly reviewing the relevant literatures on why political actors use institutional agents as a means of generating information. In particular, I introduce informational theories of legislative committees to explain why formal IOs are informative and why some institutions transmit information more efficiently than others. In the second section, I present the theoretical argument and hypotheses, and I discuss observable implications. The third section presents a case study of U.S. efforts to work through the Security Council during the 1990–91 Iraq conflict. Detailed qualitative analysis is the most appropriate method for uncovering the relevant causal mechanisms. I then briefly consider an alternative argument drawn from constructivism—and arguably reflecting the conventional wisdom—that explains the benefits of working through IOs in legitimacy terms. The final section summarizes and discusses additional implications of the argument.
For years the nexus between institutions and power remained understudied by IR theorists busy arguing that either one or the other was important. A handful of recent works shed light on why powerful states subject themselves to institutional entanglements in the security sphere. Ikenberry argues that powerful states can build institutions to exhibit “strategic restraint,” a form of self-binding that lowers the costs of maintaining world order by reducing fears of domination.8
Lake explains why states sometimes go beyond mere cooperation to create “hierarchical” security relationships that protect against opportunism.9 My puzzle is distinct: I ask why states work through institutions while exercising power in particular foreign policy episodes, not why they create or maintain institutions over time. Institutions are exogenous in my analysis. In this respect, my question is closer to Martin's investigation of how institutions benefit a state pursuing economic sanctions.10Unlike these scholars, I find the information transmission role of institutions to be more important than their ability to solve commitment problems, which are less relevant in the context of a single coercive episode. While costly constraints imposed by institutions are important in my account, they serve primarily to transmit information rather than to address time-inconsistency.11
While IOs increase the costs of backing out of commitments to a particular course of action, they typically cannot solve this problem when it comes to powerful states. The U.S. decision to abandon the UN before the 2003 war against Iraq is a good example. In fact, the IR literature frequently conflates the analytically distinct problems of signaling and credible commitment. I maintain the distinction both conceptually and empirically.
See, for example, Fearon 1997; Kydd 2000.
Political actors delegate authority to political institutions for a variety of reasons. They may do so to solve collective decision-making problems, to forge credible commitments, to reduce their workload, or to generate information.13
See Kiewiet and McCubbins 1991; North and Weingast 1989; Martin 2000; and Epstein and O'Halloran 1999. For international applications and theoretical extensions, see Hawkins et al. 2006.
See Maxfield 1997; Hall and Franzese 1998; Keefer and Stasavage 2002. These information arguments are distinct from the classic time-inconsistency rationale for central bank independence. See Rogoff 1985.
See Bawn 1995; Volden 2002.
Even more relevant to the international sphere are informational theories of legislative organization, developed most extensively in the context of the U.S. Congress.18
See Gilligan and Krehbiel 1989 and 1990; Krehbiel 1991.
These principles of information transmission by institutional agents can be usefully applied to international institutions. I highlight the distinct role played by formal IOs, as uniquely informative among international institutions, and explain how the properties of the Security Council render it especially informative when it comes to military intervention.
Coercing states face the problem of minimizing the international political costs that might be imposed by third-party states—that is, states that are not themselves targets of coercion. These costs are potentially high when coercion is conducted unilaterally and may come in the form of short-term “active” sanctions, designed to oppose the policy directly, and longer-term “passive” sanctions, designed to frustrate the coercing state over time.19
On this distinction, see Thomas 2001.

Formal IOs play a unique role in international affairs because of their independence, which derives from their ability to act with relative autonomy and neutrality.22
It is the neutrality of IOs in particular that allows them to serve as informative agents of the international community. Because they have standing memberships with diverse interests and cannot be controlled by individual states, they have two advantages as information generators. First, IOs are able and willing to impose constraints on a coercer, making signaling of limited ambitions possible; and second, IOs act as representatives of the international community, allowing them to generate information on policy consequences that is regarded as disinterested and thus credible. Intentions information and policy information are important to third-party leaders and their publics as they formulate a response to the coercive action.Unilateral claims by a coercing state clearly lack the neutrality of IOs in the eyes of the international community. Simple multilateralism, as an intermediate strategy between unilateralism and IO-based action, provides only limited information; ad hoc coalitions are by definition composed of like-minded states, as the phrase “coalition of the willing” reflects. In the language of the legislative signaling literature, these coalitions are homogeneous and usually composed of preference outliers. Because the ideal point of the median member of such a coalition is close to the ideal point of the coercer on the question of intervention, the coalition is not likely to impose substantial constraints and approval from the coalition is not informative to the median member of the international community. Figure 1 maps these preferences. Among the most robust findings in theories of strategic information transmission is that actors with more similar preferences can send more informative signals to each other.23
See Crawford and Sobel 1982; Lupia and McCubbins 1994, 368.
Informational theories of legislative organization help us further understand why the Security Council plays a special role when it comes to the use of force. Figure 2 presents graphically a situation where the IO membership is both heterogeneous (reflected in a wide preference distribution) and representative (reflected in a roughly normal distribution and a median preference that matches that of the international community). In security matters, the Security Council best matches these characteristics. Approval from the Security Council—with its fifteen members representing various regions, geostrategic interests, and levels of development24
The ten nonpermanent seats are distributed geographically, with five allocated to Asia and Africa, two each to Latin America and Europe, and one to Eastern Europe.
This logic explains why regional organizations, with less diverse memberships and more parochial interests, produce a legitimation effect of lesser magnitude. The information argument presented here thus suggests that institutional variation presents tradeoffs—political benefits versus costly constraints—that affect the “forum shopping” decisions of coercing states, an extension of the framework explored elsewhere.26
Coercion through IOs is thus a calculated choice by the coercer to generate international support or, at least, to minimize opposition to its policy. This leads to the following general proposition: When powerful coercers work through IOs, they do so strategically to lower the international political costs of coercion. This proposition rules out the possibility that states act through IOs primarily because of an internalized desire to behave in a legitimate or appropriate way.27
For a discussion of this possibility, see Hurd 1999.
Burden sharing is rarely a central concern for powerful states conducting military coercion (see Finnemore 1998, 183; Chapman and Reiter 2004, 901), though it is clearly valued during peacekeeping and national-building missions.
There are two channels by which IOs transmit information during coercive episodes, each centered on a different audience. I assume that state leaders are well informed about policy alternatives and consequences in the security sphere and that IOs do not have an information advantage over them in this regard. Other leaders do, however, lack information regarding the intentions of the coercing state's leadership. Coercion is associated with expanded influence, especially when pursued by the powerful, and the precise intentions of the coercer determine how threatening its actions are and how they affect the interests of third-party states. The 2003 Iraq war provides a stark example. Before the war, governments in the region feared that the United States had ambitious goals to dominate the region, altering the strategic landscape to their disadvantage. The U.S. approach did nothing to assuage these fears. As Telhami assessed the regional mindset after the war, “Most are … concerned that the war in Iraq was merely the opening move in a larger strategy; they ask themselves which country will be next.”29
It is difficult for powerful states to reassure others that their goals are limited and unthreatening. The decision to work through a neutral IO serves as an informative signal because it imposes costs on a coercer that a more aggressive state (one with intentions that threaten third parties) would be unwilling to pay. The current IR literature certainly recognizes that institutions impose constraints on states, but conceptualization of these precise costs is not well developed. At least four overlapping costs may be imposed when coercion is channeled through an IO: freedom-of-action costs, organization costs, costs of delay, and scrutiny costs.
First, a state's freedom of action is almost always limited when coercion is channeled through an IO. History shows that IOs impose real constraints that restrict the set of policy options available to even the strongest states.30
For examples involving the UN and OAS, see Chayes and Chayes 1995, 41–42. Even NATO, composed of like-minded states, imposed profound constraints on its superpower leader during the Cold War (Weber 1992) and the Bosnia crisis (Papayoanou 1997).
Second, coercers face organization costs—including the costs of communicating, bargaining, and reaching common positions—when they work through an IO.31
Olson 1965, 47.
The third type of cost, delay, is largely a product of the first two. Involving a neutral IO implies a willingness to engage in diplomacy and to wait for approval of the policy. Finally, working through an IO increases the level of post hoc scrutiny to which a coercer is subject. Since IOs increase transparency and require a more public accounting of actions, the international community is able to track the behavior of a state that chooses to work under their auspices. Moreover, exchange and discourse within an IO tends to reveal information about states' preferences and intended actions,33
See Martin 1992; Wallander 1999.
Lupia and McCubbins 1994, 368.
These various costs, which I refer to generally as the costs of constraint, allow the coercer to send meaningful information regarding its intentions. Showing restraint and a willingness to cede some control reassures nontarget states, which are less likely to oppose the intervention.
H1 (Intentions information): Channeling coercion through an IO sends a signal of benign intentions to leaders of third-party states, thereby increasing the likelihood of international support.
However, even if other state leaders determine that supporting the coercive policy is in their national interest, they may face domestic barriers to doing so. They must convince their publics that supporting another state's use of force is justified. IO approval helps overcome this additional obstacle by sending policy-relevant information to domestic publics abroad.35
Publics may also value information about the coercer's intentions. I assume that leaders, preoccupied with international competition, are relatively more concerned than publics about intentions information and thus emphasize the role of policy information with respect to publics.
While IR scholars have paid increasing attention to how domestic publics influence state interests and policy, the role of domestic publics abroad is not well understood. Members of publics are poorly informed relative to leaders; they lack knowledge regarding the reasons for a given policy and the relationship between the policy and potential consequences. This is most acute in international affairs, where issues are less salient and publics are exposed to little debate and information. Because individuals also have negligible influence on foreign policy, each has little incentive to gather and analyze information. In the context of coercive intervention on the part of another state, publics lack policy information in two related ways. First, they do not know if the policy serves collective interests or whether it reflects selfish interests with potentially undesirable consequences. Second, they do not know if the proposed policy is a reasonable means to achieve the stated goals.
Ignorance, however, does not imply indifference. Publics seek “information shortcuts” to assess international issues,36
and IO endorsements can perform this function. Because the claims of IOs are more neutral than claims of individual governments or ad hoc coalitions, the information they convey regarding a policy is more credible and meaningful. This is evidenced by public attitudes toward the search for weapons in Iraq before the 2003 war. Two-thirds of Canadians surveyed in January 2003 said they would believe the UN rather than the administration of U.S. President George W. Bush if there was disagreement over the state of Iraqi weapons.37Ipsos-Reid/CTV/Globe and Mail poll, released 17 January 2003.

Through this process of policy information transmission to domestic publics abroad, a coercer that achieves IO approval makes it easier for foreign leaders to offer support. In “two-level games” terms, the information transmitted to publics increases the size of the domestic win-set for third-party leaders by minimizing internal opposition. This second path of information transmission is captured in a second hypothesis:
H2 (Policy information): IO approval informs domestic publics abroad that the coercive policy has desirable consequences, thereby increasing the likelihood of international support by minimizing domestic opposition.
The most definitive evidence of the information transmission argument would uncover the motivations of the coercing state's leadership and would show that third parties—both leaders and publics—receive the information hypothesized and react to it accordingly. It is impossible to directly observe intentions or whether particular information has been received, though there are reasonable indicators that shed light on the processes hypothesized here, and consideration of different types of evidence can increase one's confidence.
The framework rests on the proposition that powerful states channel coercion through IOs in a calculated effort to reduce the international political costs of coercion. Two types of evidence shed light on this argument. First, one should see leaders express that their motivation for working through an IO was indeed a desire to reduce international political fallout, and this should be confirmed by contemporaneous observers. Alternative motivations, such as a logic of appropriateness or a desire for material support from the IO, would have to be ruled out. Second, one can demonstrate that the political costs of coercion would have been higher absent IO involvement. This can be done by carefully tracing international reactions within the case and through comparisons to similar cases that vary in terms of IO involvement.
For the first hypothesis, on intentions information, one should observe the imposition of costly constraints on a coercer as a result of IO involvement. One should also adduce evidence that foreign leaders were concerned about the threat posed by the coercer, and that the costs of constraint served to allay such concerns. This is best done through in-depth case research and the use of counterfactual arguments to demonstrate that international reactions would have been different absent IO approval.
The second hypothesis—that IO approval sends policy information to domestic publics abroad—is the most empirically challenging. It is impossible to know precisely how and why individuals updated their beliefs about a given policy. One should first establish that third-party leaders are constrained by domestic opposition from supporting the coercer and that they view IO involvement as key to alleviating this problem. In terms of public opinion, a procoercion shift should occur following IO approval. One can also compare public opinion in cases that vary in terms of IO involvement; IO authorization should correlate with more favorable attitudes toward the action.
I propose an additional indicator for Hypothesis 2, based on the framing strategies of leaders, that helps capture both the concerns of publics and the information they receive during coercive episodes. If leaders believe that IOs can transmit politically useful information to their publics, one should see them frame their actions in specific ways in statements designed for public consumption. Leaders should stress not only involvement by the IO but also its informative properties, namely, its neutrality as a function of its diverse and representative membership. Because the press “index” their coverage of foreign policy to the statements of high-level government officials,42
how events are framed by these officials shapes the information received by publics. Indeed, strategic communication by leaders can even stretch across borders to reach foreign audiences directly.43 To the extent that leaders are well informed about their constituents, their framing strategies also should shed light on what type of information is important to publics as they assess policies.Given these indicators, assessing the argument requires fairly detailed analysis of a given case to reveal the information transmission processes, with contextual comparisons to other cases to isolate specific variables and assess counterfactuals. The case study below is guided by the arguments and observable implications summarized in Table 1.
Following the Iraqi invasion of Kuwait on 2 August 1990, the United States went to great lengths to work through the UN to pressure and ultimately expel Iraq from Kuwait, seeking Security Council resolutions at every stage of the conflict. Resort to force came only after twelve resolutions condemning Iraq and imposing various sanctions, culminating in the passage on 29 November of Resolution 678, which authorized member states “to use all necessary means.” Most observers of Gulf War diplomacy agree that by turning to the Security Council the United States was able to “legitimate” and achieve greater support for its use of coercion. But few analysts go the next step. Why and how was the UN able to perform this function? Why did its role change how the international community reacted to events? Understanding the logic of information transmission helps address these questions and explain why the United States chose an IO-based strategy.
The 1990–91 Persian Gulf conflict is an ideal case for assessing the arguments presented here. Because the episode involves an extremely powerful state using military force against a much weaker one, it represents an unlikely case for showing the importance of institutional involvement. The opportunity costs of using institutions are higher for powerful states—they have more to lose by ceding control. U.S. efforts to gain Security Council support have indeed been rebuffed on multiple occasions, a reflection of the body's diverse interests, its supermajority voting rules, and the veto power of the permanent members, who frequently have divergent preferences.44
Looking at a case where the most powerful state turns to the most neutral IO should render salient the tradeoffs and causal mechanisms identified in my theoretical argument.In military terms, the Gulf War was remarkably decisive. The vast majority of the forces and equipment were American, and in fact the coalition proved to be a significant burden.45

In the end, the United States suffered no serious diplomatic setbacks as a result of the war. The political success of U.S. efforts was reflected in the widespread support it achieved, summarized in Table 2. Almost forty countries contributed personnel to the coalition, and more than twenty provided military hardware. Financial contributions of $54 billion were also made to the United States, mostly from Saudi Arabia, Kuwait, the United Arab Emirates, Japan, and Germany.
But perhaps the same third-party states that supported the U.S.-led operation would have done so regardless of any UN involvement. There may even be endogeneity: UN approval may have been a result rather than cause of widespread international support. This argument can be rejected for two reasons. First, most states that ultimately supported the intervention were deeply torn initially and through much of the prewar period. Most Arabs loathed the idea of Western troops entering the region, and some saw merit in Iraqi leader Saddam Hussein's accusations against Kuwait. Even King Fahd of Saudi Arabia, facing the most immediate threat of continued Iraqi aggression, strenuously resisted U.S. assistance.50
Heikal 1992, 213.
By November, with the exception of the United Kingdom, every European and Arab member of the emerging coalition, as well as Canada and the Soviet Union, had made Security Council approval a condition of their support for offensive action.51

As the world's only superpower contemplated the use of military coercion, the international community was clearly concerned with U.S. intentions. Goals that included overthrowing Saddam, occupying Iraq or establishing an indefinite, large-scale military presence were viewed as threats to third-party interests. Goals limited to restoring the pre-invasion status quo, by contrast, were generally viewed as benign.
Gulf states had a genuine concern for their sovereignty and the encroachment of U.S. military influence.52
Those states most immediately affected, such as Kuwait and Saudi Arabia, were effectively being asked to submit to protectorate status for the duration of the American military presence. Lake 1999, 235–36.

The United States thus faced the problem of signaling its intentions. As Hypothesis 1 suggests, by channeling its coercion through the Security Council, the United States assumed costs that helped signal its limited goals. Aside from the operational difficulties that arose from putting together a multinational force, U.S. political and military leaders faced a number of real costs in the form of delays, limits on policy autonomy, and additional scrutiny. The Bush administration was constrained by the methodical decision-making process and influence costs that resulted from seeking approval during each phase. As one senior administration official lamented, “When you try to bring people on board, you have to listen to them.”57
Newsweek, 1 October 1990, 20.
At two stages in particular U.S. policies were delayed and adjusted to mollify the Security Council: the decision to enforce the initial embargo on Iraq and the decision to launch the military operation called Desert Storm. Resolution 661, passed on 6 August 1990, imposed a trade embargo on Iraq. Though the United States—and the United Kingdom, whose navy was also patrolling the Gulf—was willing and able from the start to enforce the embargo, ships were allowed to pass through the blockade for weeks. Scowcroft describes the dilemma:
The question was, do we move unilaterally to stop them, or do we wait and try to get additional authority from the UN? We had lengthy discussions with the British about it and of course [British Prime Minister Margaret] Thatcher said go after the ships…. [U.S. Secretary of State James] Baker was insistent that we wait. He convinced the President we would lose the Soviets (who were still adamantly opposed to using force) and perhaps the chance for a positive vote in the Security Council on enforcement if we went ahead unilaterally.58
Bush and Scowcroft 1998, 351–52.
U.S. National Security Advisor Colin Powell and Defense Secretary Richard Cheney agreed that, for political reasons, they should wait for UN approval.59
Woodward 1991, 284.
The French and Soviets worried that enforcement action would provoke retaliation by Iraq and thereby trigger war, and they argued that Resolution 661 alone could not be used as authorization. The Soviets were the major obstacle, delaying by at least ten days a new resolution approving force.60
Toronto Star, 25 August 1990, A1.
Waiting for UN endorsement to enforce the embargo was costly, beyond the fact that supplies were reaching Iraq in the meantime. To begin with, there was a credibility issue, as Freedman and Karsh point out: “Here was the first potential use of force and the United States dare not back down lest it appear a ‘paper tiger.’ If it hesitated, inevitable questions would be raised about its readiness to stay the course.”61

Independent, 27 August 1990, 7.
For U.S. decision makers, the next great debate—and delay—was over the launching of Desert Storm. Thatcher again warned Bush that going back to the UN would constraint them unduly. In seeking a further resolution, she argued, “We risk amendments,” therefore it was preferable to “go to war on our own terms.”65
Bush and Scowcroft 1998, 384.
In the end, the United States waited four months from the invasion until Resolution 678 authorized the use of force. Considerable diplomacy and consultations took place before the United States could even propose language for a resolution, and Security Council voting rules (the dual obstacles of supermajority and the veto) gave other governments considerable leverage. A senior Bush administration official described the difficult process of garnering the necessary votes: “We have an idea of the kind of resolution we'd like. But that's very different than presenting countries with draft language of a proposal that you are going to consider tabling in the council…. Each country is one vote; you need nine votes to pass a resolution, and some are in different places on this.”66
Quoted in Washington Post, 16 November 1990, A21.
New York Times, 11 November 1990, A1.
The Soviets in particular pushed for more moderate language and insisted on more time for diplomacy throughout the month. Even when a date for a Security Council vote was settled, while the United States hoped to set a relatively prompt deadline for Iraqi withdrawal, the Soviet Union and France insisted on a “pause for peace” as a condition of the resolution's passage. The Soviets asked for a 31 January 1991 deadline; the French compromise of 15 January was selected. The very idea of an “announced” war, it should be noted, represented a constraint, as U.S. planners had preferred a more flexible approach.68
Ibid., 14 November 1990, A1.
Delay was costly for three reasons. First, it allowed Saddam to prepare for hostilities and required the size of the Allied force to be augmented accordingly. Bush worried in early January that the United States would pay a high price in lives by allowing the Iraqi army to dig in.69

This argument was made most prominently in a Washington Post editorial by Henry Kissinger. Washington Post, 11 November 1991.
The wait was valuable politically: it satisfied European countries that hoped to further explore diplomatic means and allowed Arab leaders to investigate “Arab solutions.” It also showed that the United States was willing to be constrained and to accommodate the interests of others. Reflecting the success of this benign signal, Gorbachev told Baker in early November, “[We] have noticed that in this situation you are not losing your cool.”72
Quoted in Aldrich-Moodie 1998, 18.
When the United States, with operation Desert Storm underway, declared a cease-fire on 28 February, reactions were mixed. The abrupt end and Saddam's continued rule sparked accusations that the coalition had not truly succeeded, and within months of the war Bush's popularity ratings had plummeted. Early in the episode, various options, including invasion and the removal of Saddam, were on the table. The IO-based strategy required that these more ambitious goals be removed to generate consensus in the Security Council. Bush knew it would be costly to accept and adhere to a limited UN mandate, as prewar polls showed a strong public desire to remove Saddam.73

Relinquishing some decision making to the Security Council allowed the United States to credibly signal that it preferred a limited operation (restoration of the pre-invasion status quo) and was not motivated by hidden ambitions. U.S. assertions before the Security Council that it had limited goals consistent with the UN mandate76

From the time U.S. troops began arriving to defend Saudi Arabia, leaders throughout the international community faced tough domestic political questions in deciding whether to support a U.S.-led invasion. Potential coalition governments knew that IO approval would help them “sell” support of the war to their domestic audiences, and this provided additional motivation to push for a Security Council-based approach. For their part, U.S. policymakers clearly had foreign publics in mind when they chose to work through the Security Council. Scowcroft believed that the UN “could provide a cloak of acceptability to our efforts and mobilize world opinion behind the principles we wished to project.”78
Bush and Scowcroft 1998, 491.
When they address domestic politics, scholars studying the role of IOs in U.S. military intervention typically focus on the audience at home.79
By focusing instead on the role of foreign publics, I am not arguing that politics in the United States were unimportant—multilateralism benefited the Bush administration in terms of public opinion and the debate in Congress. Nevertheless, decision makers were not primarily motivated by political concerns at home when they turned to the UN. Bush was willing to proceed to war without majority approval and without a favorable vote in Congress.80See Powell 1995, 499; Bush and Scowcroft 1998, 446.
In the 1990–91 case, many governments, having concluded that it might be in their interest to support U.S. action, initially felt constrained by their publics from doing so. Domestic audiences were most skeptical in the Arab and Muslim world, where Western military intervention was an especially sensitive issue. Following the Iraqi invasion, no Arab regime dared to call publicly for U.S. assistance; even Kuwait's desperate call for international help was qualified with an explicit preference for an “Arab solution.” A study of Arab public opinion during the Gulf War concludes that Arab governments, though autocratic, were constrained by domestic attitudes and calibrated their policies accordingly.82
The domestic political challenges facing leaders outside the region were qualitatively different but also important. As one newspaper characterized the situation in Europe in late August 1990, while condemnation of Iraq was unanimous, “domestic political difficulties and wariness about jumping aboard a U.S. bandwagon are still causing division on the issue of military action outside a UN umbrella.”83

Quoted in Freedman and Karsh 1993, 231.
These domestic political barriers were largely removed as a result of the UN's involvement. As U.S. policy toward Iraq became increasingly enmeshed in the Council, domestic opposition around the world was diminished to the point where few governments felt constrained. Despite lingering resentment, fears of upheaval in the “Arab street” were not realized. Governments with Muslim populations saw a UN-based approach to Iraq as key to overcoming domestic barriers to the intervention. Egypt and Turkey, for example, strongly urged Baker to seek Security Council resolutions “to protect themselves against domestic political opposition.”86

Once Arab leaders decided that the risks of a more powerful Iraq were too great and that Western intervention was sufficiently unthreatening, they targeted their publics with a “coordinated information campaign” centered around the multilateral nature of the intervention.88

Various Western leaders also relied on the UN to make support politically possible. France would not have participated outside the aegis of the UN. Though French President François Mitterrand felt that Article 51 was sufficient from a legal perspective, he knew it could not justify military coercion to his domestic audience. “Article 51 doesn't mind public opinion,” he explained to Baker. “Fifty-five million French people are not international lawyers. We need that resolution [to authorize the use of force] to ensure the consequences it will entail.”93

The details of leaders' framing strategies are also consistent with the information rationale for Security Council influence. Beyond references to UN involvement, in statements designed for public consumption U.S. and third-party leaders stressed certain characteristics of the Security Council to emphasize its neutrality, namely that its membership was heterogeneous and representative of the international community. Baker understood the political importance of framing the conflict as a collective effort in the collective interest: “We believed it was imperative to keep the debate from turning into an Iraq-versus-the-United States confrontation, which would have made it more difficult to build and maintain a coalition.”96

For examples of such statements by representatives of Canada, Ethiopia, Finland, France, the United Kingdom, Malaysia, Romania, the Soviet Union, and Zaire at key junctures of the Iraq episode, see the following UN documents: 2/PV.2934, 9 August 1990, 13–15, 16, 21; S/PV.2938, 25 August 1990, 33, 38, 48; S/PV.2943, 25 September 1990, 33, 46, 66, 74; and S/PV.2963, 29 November 1990, 79. It should be noted that statements made before the Security Council are carefully crafted and intended for public consumption, not for active deliberation or debate.
In other words, leaders were careful to stress the institutional characteristics that render institutional agents—from legislative committees to IOs—most informative: a heterogeneous and representative membership. While public statements explain little about what motivates speakers themselves, these statements are potentially revealing with respect to their intended audience. Based on the two assumptions identified in the previous section—that the information received by publics about foreign affairs derives largely from their leaders, and that leaders have some understanding of what information is persuasive to their publics—this lends further support to Hypothesis 2.
Finally, a useful comparison of international public opinion can be made to the 2003 Iraq war, conducted with no IO mandate. While roughly 70 percent of Western Europeans supported intervention in the first Gulf War, only 19 percent of Europeans polled by EOS Gallup Europe in January 2003 supported the second.103

In both wars, even when government leaders had decided that supporting the intervention was in their country's interest, many faced domestic opposition. The Security Council's imprimatur was the most powerful tool for convincing these publics that the coercive policy was reasonable and worthy of support. As one Turkish diplomat notes, contrasting the 2003 Iraq war with the first, “[A] resolution gives us something to work with domestically; we just didn't have that in the second case.”105
Author's interview with a Turkish diplomat, New York, 13 November 2003. The interviewee was confident that UN authorization of the 2003 intervention would have swayed public opinion sufficiently to allow more active support, such as providing a base of operations for U.S. ground troops.
I have offered indirect but suggestive evidence that channeling coercion through the UN during the 1990–91 episode served to transmit policy-relevant information to publics around the world, thus removing a domestic political barrier to third-party support. Many leaders were constrained by domestic politics from supporting the United States initially, but these constraints largely disappeared as the policy became firmly entrenched in the Security Council.
My empirical discussion has focused largely on providing confirming evidence for my information argument. I have briefly considered specific alternative explanations (domestic politics in the United States, burden sharing, and endogeneity) for the Security Council's role but I have not directly addressed the most prominent theoretical alternative: that the observed “legitimation effect” of IO approval rests on the importance of legitimacy. Legitimacy is fungible and can be transferred from an institutional holder to another actor.106
Thus it is possible that the international community views IO approval as conferring legitimacy on state actions, appealing to an internalized norm that legitimate behavior is appropriate and thus worthy of support. This legitimacy logic arguably represents the conventional wisdom for understanding the political effects of IO approval.It is difficult to disentangle these distinct logics—rational information transmission versus normative legitimacy—since their broad effects are observationally equivalent. In both cases IO approval leads to more international support. On closer inspection, however, there are distinct observable implications for both mechanisms that can help one assess their relative explanatory power in a given case. I consider three sources of evidence in this section: the design features of the Security Council, the behavior of foreign leaders, and the attitudes of publics.
The legitimacy and information rationales make different predictions about what sorts of institutional design features generate the greatest political effect. I have noted the consensus among scholars and practitioners that the UN, especially the Security Council, is a uniquely powerful legitimizer of state policies. Leaders covet its approval over regional endorsements and publics are more likely to support the use of force endorsed by the Security Council as compared to regional IOs or allied coalitions.107

See Schachter 1989; Voeten 2005.
Moreover, if legitimacy is operating, one would expect smaller IOs with more homogeneous memberships to be most influential in generating support. Constructivist scholars show that norms and socialization processes matter most in more intimate, “in-group” settings.109
See Checkel 2001; Johnston 2001.
See Franck 1990; Hurd 1999.
Schimmelfennig (1998/1999) makes precisely this argument.
Johnstone 2003, 456.
Turning to the behavior of leaders, I have already shown that U.S. policymakers, in seeking IO approval, were motivated instrumentally and not by an internalized desire to act appropriately. But perhaps foreign leaders were motivated differently. If legitimacy is operating, one should see leaders supporting the policy because it is the “right” thing to do and not because of a cost-benefit assessment of self-interest.113

It is perhaps more likely that foreign publics reacted to Security Council approval through legitimacy rather than information mechanisms. Two sources of evidence suggest this is not the case. First, while Security Council approval led to more international public support for the U.S.-led intervention, this support did not translate into a commensurate desire to actively participate in the intervention. Arguably, a normative motivation would be associated with a desire to participate in what is perceived as a legitimate action, just as legitimate rules inspire a felt obligation to comply. In October 1990, while 73 percent of French approved of Bush sending troops to Saudi Arabia and 75 percent approved the use of force, only 42 percent of those polled in early November approved of French participation. On the eve of war, while support for the use of force was high, 57 percent were opposed to French military involvement. Similarly, while most Spaniards supported Bush and favored the use of force, 60 percent were against their government's move to send troops and warships. Three-fifths of Italians favored the use of force and approved of Bush's actions, but only a third favored sending Italian combat troops.116

The second source of evidence again involves the public statements and framing strategies of leaders. If the legitimacy conferred by IO approval is important to publics, we should see leaders framing Security Council involvement in legitimacy terms. I analyze the content of the four Security Council resolution debates most closely associated with the question of coercion during the Gulf War conflict: the 6 August discussion of Resolution 660, imposing an economic embargo; the 25 August discussion of Resolution 665, authorizing enforcement of the embargo; the 25 September discussion of Resolution 670, extending and strengthening the blockade; and the 29 November discussion of Resolution 678, authorizing force.117

While there is considerable discussion of the informative properties of the Security Council, as discussed above, there is virtually no mention of its institutional legitimacy or the legitimacy of its resolutions. In 325 pages of transcribed speeches, the terms legitimacy and legitimate are used approvingly to describe the Security Council or its resolutions only once (by the Soviet Union on 25 September). Ironically, the only representatives who address the issue of Security Council legitimacy are from Cuba and Iraq—and they do so to condemn its actions as illegitimate. The question of legitimacy was certainly on the minds of Security Council representatives, as they referred frequently to the legitimacy of the Kuwaiti government in exile. But despite their preoccupation with the concept, in these lengthy and carefully crafted public speeches there was seemingly no concern with stressing the legitimacy of the Security Council. This suggests that their respective publics were not motivated primarily by legitimacy concerns and were not swayed by Security Council approval through legitimacy-based mechanisms.
This section by no means provides an exhaustive competitive test between these two theoretical perspectives, information versus legitimacy. I have offered several observable implications of the legitimacy argument involving institutional design, the behavior of leaders, and the behavior of publics, and in each case there are reasons to question whether IO approval confers legitimacy per se on state actions. Nevertheless, especially with respect to publics, it is quite likely that actors are motivated by both rationalist and normative concerns, and any complete theoretical account of the legitimation effect should include both components.118
For an effort to synthesize these perspectives, see Thompson 2005.
Understanding why even the most powerful states subject themselves to the constraints of international institutions remains among the most intriguing theoretical puzzles for IR scholars. I explore the theoretical intersection of power and institutions by asking why states often channel coercive policies through IOs. This question has typically been answered by pointing to the legitimation effect of IO approval, however the causal mechanisms of this phenomenon are not well understood. I provide a largely rationalist theoretical explanation based on the informative properties of institutions as agents of the international community. Formal IOs that are neutral, with heterogeneous and representative memberships, are uniquely capable of providing credible information regarding a coercing state's intentions and the consequences of its policy. Leaders and publics rely on this information when deciding whether to support or oppose the action.
I conduct a detailed case study to uncover the dynamics of information transmission. During the 1990–91 Gulf War, the world's only superpower showed a willingness to cede some control to an IO that was able to independently assess and impose costly constraints on the coercive policy. By working through the Security Council, the United States was able to send information regarding its intentions to other states leaders and to send policy-relevant information to publics abroad. This information increased international support for the intervention, thus explaining the incentives to seek IO approval. A preliminary comparison suggests that legitimacy-based explanations cannot account for the behavior of state leaders or their publics in this case, and fail to explain the unique role of the Security Council as an endorser of military intervention in the contemporary world.
The framework can be extended both theoretically and empirically. I offer a ceteris paribus argument insofar as a state may bypass IOs when the anticipated political costs of action are already low or when there is high sensitivity to the costs of constraint. Elaborating these tradeoffs would help one understand how coercers choose among institutions with different designs and thus different constraints and informative properties. I only begin to address these “forum shopping” issues here. While I have treated institutions themselves as exogenous in my theoretical model and empirics, my argument has implications for the endogenous treatment of institutions. The political advantages of channeling statecraft through IOs helps explain why powerful states create and join these institutions in the first place, and why they design them with certain properties. To further explore the boundaries of the argument, it should be applied to cases of economic and diplomatic coercion as well. While the nature of costs and benefits will change in these settings, the central theoretical insights should apply beyond cases of military intervention.
Finally, a wider range of hypotheses and observable implications should be used to compare the rationalist framework presented here with a norm-based framework based on the importance of legitimacy. More eclectic theorizing and testing will help one “get to the bottom” of the widely observed legitimation function of IOs, an increasingly important phenomenon in international affairs.
