Nuclear Issues

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.

 Stephen Walt decided to look back to see if 2022 had gone according to his expectations. In his last column of 2021, he had described "Biden’s 2022 Foreign-Policy To-Do List." What did he get right, what did he get wrong, and how well did the Biden administration perform?

Stephen Walt offers a tentative and far-from-comprehensive survey of what scholars have to say about the war in Ukraine.

Wedge strategy theory explains how states use strategic arms control to divide adversaries by affecting their trust, threat perceptions, and beliefs about a commitment’s trade-offs. Examining three landmark arms control negotiations shows how the wedge motive was a key component to these negotiations.

The historian Fredrik Logevall has written a grand fresh take on the life of John F. Kennedy, as if to reignite an old flame. He's given us a chance to remember politics as the sport of great minds and hearts, high language, serious stuff.

Stephen M. Walt critiques to Francis Gavin's review of his 2018 book, The Hell of Good Intentions: America's Foreign Policy Elite and the Decline of U.S. Primacy, and offers his view on how one should not evaluate U.S. grand strategy.

Despite the far-reaching effects of the current pandemic,  the essential nature of world politics will not be transformed. The territorial state will remain the basic building-block of international affairs, nationalism will remain a powerful political force, and the major powers will continue to compete for influence in myriad ways. Global institutions, transnational networks, and assorted non-state actors will still play important roles, of course, but the present crisis will not produce a dramatic and enduring increase in global governance or significantly higher levels of international cooperation. In short, the post-COVID-19 world will be less open, less free, less prosperous, and more competitive than the world many people expected to emerge only a few years ago.

Domestic politics play a significant role in nuclear decisionmaking under two conditions: when uncertainty over the nature and intensity of a threat is high, and when leaders are incentivized to centralize nuclear policymaking.

What explains the scale and speed of nuclear proliferation? One key factor is the level of competition among suppliers in the market for nuclear materials and technologies. When suppliers form a cartel, fewer countries can acquire what they need for a nuclear weapons program. If great power competition intensifies, suppliers will find it harder to cooperate and nuclear proliferation could accelerate.
