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.

The Washington Declaration signed by U.S. President Joe Biden and South Korean President Yoon Suk-yeol yesterday should be a ringing reminder of one of the greatest achievements of U.S. national security strategy: its decadeslong success in preventing the proliferation of nuclear weapons. The agreement strengthened nuclear deterrence coordination between the two allies and offered a greater sense of assurance that South Korea falls under the U.S. nuclear umbrella.

 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.

Stephen Walt asks whether the United States is a good model for other liberal states and whether its policy judgments are ones that others should trust and follow, especially with respect to foreign policy.  He argues that—on balance—the answer to both questions is "no."

Ambassador Thomas Graham Jr. and Mariana Budjeryn recount Taiwan's history which reveals the island democracy's resilience, as well as how — and why — the United States should reinforce its support.

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.

A comparative analysis of the United States’ and the Soviet Union’s previously underexplored radiological weapons programs identifies the drivers behind their rise and demise. The findings of this analysis illuminate the factors likely to affect the pursuit of radiological weapons by other states in the future.

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.
