International Security

Russia's 2022 invasion of Ukraine illuminated the long profound shadow of nuclear weapons over international security. Russia's nuclear threats have rightfully garnered significant attention because of the unfathomable lethality of nuclear weapons. However, the use of such weapons in Ukraine is only one way—albeit the gravest— that Russia could challenge the global nuclear order. Russia's influence extends deep into the very fabric of this order—a system to which it is inextricably bound by Moscow's position in cornerstone institutions such as the Nuclear Non-Proliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA). From withdrawing from key treaties to stymieing resolutions critical of misconduct, Moscow has demonstrated its ability to challenge the legitimacy, relevance, and interpretations of numerous standards and principles espoused by the West.

Americans have long seen their country as morally exceptional, but their exceptionalism actually comprises three distinct views. Whichever prevails in next year's presidential election will have significant implications for ongoing conflicts in Europe, Asia, and the Middle East.

During foreign policy disputes involving China and some of its most important commercial partners, why do local leaders punish or protect foreign commercial actors? The decision comes down to the political incentives facing each local leader. Understanding this variation is important because how local leaders treat foreign businesses can influence the overall effectiveness of the Chinese government’s economic coercion against foreign states. 

Power transitions affect a state’s ability to exercise economic statecraft. As a dominating and a rising power approach parity, they face structural incentives to decouple their economies.

In the absence of an alternative shorthand, politicians and journalists most likely will continue to use "Global South" for the foreseeable future. Yet anyone interested in a more accurate description of the world should be wary of such a misleading and increasingly loaded term.

Recent scholarship on Sino-Indian relations in the 1950s has emphasized cooperation, revising previous narratives of an inexorable march towards the 1962 border war. This article reassesses that cooperation by focusing on India's role as an intermediary between the unrecognized government in Beijing and the United Nations (UN). Chinese sources reveal that Sino-Indian cooperation over UN affairs was complicated by competing conceptions of how the decolonizing world should fit into the international system and who should be at the helm. Despite such disagreements, the Cold War UN provided a setting where divergent post-colonial visions could be sublimated into meaningful international cooperation.

Joseph S. Nye writes that following the first Republican debate of the U.S. presidential primary season, there is good reason to worry about what a Republican victory in 2024 would mean for the U.S.-led global order. History suggests that when Americans embrace retrenchment, much more than just liberal internationalist principles suffer for it.
