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 analyzes U.S. reliance on its toolbox of coercive instruments and stubborn adherence to unreachable objectives. He concludes that both are significant obstacles to a more effective U.S. foreign policy.

Calder Walton says both seek to topple the United States from atop world stage, with China's blend of money, influence, all-hands-on-deck approach posing the greater threat.

Joseph Nye considers U.S. options for risk reductions as nuclear threats escalate and China-Taiwan tensions rise.

 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 provides A realist POV on the war in Ukraine, competition with China, COVID, and more in the second part of an interview with Foreign Policy Editor-in-Chief Ravi Agrawal.

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

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

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.

Stephan Walt writes that Trump's foreign-policy instincts might be more sound—but he has forfeited the chance to lead.
