A multipolar world would be disastrous for international security

Writing in The Guardian this week, Yale Law professors Ash Bâli and Samuel Moyn celebrate what they suggest is the end of the unipolar American-led international order. To borrow from Mark Twain, I suspect that news of America’s superpower death is exaggerated. Still, in their optimism about how a new multipolar order might be established, Bâli and Moyn regurgitate the error of idealists. Namely, their associated belief that nations will cooperate absent coercive restraint in the contrary. While many democracies and even some dictatorships/monarchies prefer cooperation, states ultimately act in their own self-interest.The professors ignore this reality. Instead, they “imagine a multipolar world that might secure peace better than the old order ever did.” To reach this nirvana, they call for nations to accept four commitments. These commitments rest on “one clear, narrow and urgent proposition: no state is safer in a world in which coercion is unconstrained because every exception claimed by one power becomes available to its rivals.”It’s nice rhetoric. Its structural weakness should appear obvious, however. While some nations would broadly align against coercion under this principle as they do today, others, such as China, Russia, Iran, and North Korea would continue to embrace coercion as a primary tool of foreign policy. Together, these four commitments thus underline why a world without the economic and military dominance of the United States and its allies would be a far worse world than today’s. Each point has its own distinct challenges in this regard. “First,” Bâli and Moyn suggest, “states should reaffirm and strengthen limits on the right of self-defense they can claim under the U.N. charter.”This sounds good, of course. Just as Russia invented a threat from Ukraine to justify its 2014 and full-scale 2022 invasions, Iran continues to claim self-defense in shutting down civilian maritime traffic in the Strait of Hormuz. The basic problem is that some nations care nothing for rhetorical commitments. Nor will nations share a common view of what constitutes self-defense. Just as one person might strike first, perceiving an imminent threat from someone who is screaming profanities at them with clenched fists, another might wait to defend themself until the first punch is thrown.Similarly, while the United Kingdom might perceive Iran’s nuclear program as a major threat to international stability, its sense of what Israel should do about that threat will be different from the heightened concern that program provokes in Israel. Put simply, absent an all-powerful, respected U.N. military force, etc., that can enforce common understandings, nations aren’t going to align under a restrictive definition of self-defense. Nor, absent the ability of such a UN force to restrain them, will nations such as China, Iran and Russia abandon expansive notions of self-defense in order to justify their own aggression.The writer’s second argument is that “states should recommit to the inadmissibility of annexation or territorial acquisition by force, including de facto annexation accomplished through occupation, settlement, demographic engineering, or the creation of irreversible facts on the ground.”We know how this one goes. Russia would sign up to this principle but then breach it with unrepentant passion. As it has done in Georgia and in Ukraine. As it wants to do in the Baltic states. China would similarly also sign up to this principle, only to then defend its seizure of the South China Sea, of Indian territory, and of Taiwan as acts of territorial defense.Bâli and Moyn’s next argument is that “powers should commit not to instigate, enable or intensify proxy wars against one another. Defensive support to a state resisting aggression is one thing; measures designed to prolong war or turn a local conflict into a means of bleeding a rival are quite another.”Note the deceptive language. Defensive support for “resisting aggression” is OK, but “bleeding a rival” is not. While this cautious rhetoric is designed to make their argument seem sensibly calibrated, the writers are creating space for a state to argue against support for Ukraine, for example, on the basis that said support is designed to “bleed” Russia. Certainly, that is what the Kremlin argues. And in the absence of a universal understanding of what proxy wars and defensive support constitute, these commitments wouldn’t be worth the paper they are written on.CHINA’S MANIFESTLY GREATER THREAT: WHY GEN. DAN CAINE IS WARNING TRUMP ABOUT IRAN MUNITIONSFinally, we’re told that “states should not furnish military assistance or permit or sponsor arms sales that predictably abet gross violations of rules against aggression or atrocity.” The authors make clear that they have arms supplies to Israel in mind here. But do we seriously expect Russia to suspend its global arms sales? Or Iran to stop selling drones to Russia and other Western adversaries? After all, those arms sales undergird strategies to earn foreign capital and bolster foreign influence.The writers leave us with a utopian rallying cry: “The task now is to stop mourning the old order, refuse the new lawlessness, and make restraint the thin, hard core of whatever comes next.”Again, it sounds good. But reality suggests it will be rather hard to build an international order centered on “restraint” absent nations which can restrain those who have no functional use for restraint.
