Nuclear Issues

Europe after the Russo-Ukrainian War must develop a new security structure to defend against any Russian aggression. The safest option is a non-offensive, confidence-building defense. This option includes proposals such as the “spider in the web” strategy and the “porcupine” strategy to provide for European security in a region threatened by Russian expansion—without relying on the threat of nuclear war. 

Joseph Nye considers lessons from his own work on preventing the spread of nuclear technology in the 1970s.

Stephen Walt critiques Henry Kissinger's professional life by dividing it into three parts: as an academic at Harvard; as national security advisor and secretary of state; and as an author, pundit, and sage, much of it conducted as the head of Kissinger Associates, the consulting firm he founded after leaving government.

Chinese strategists increasingly believe that U.S. nonnuclear strategic capabilities threaten China’s nuclear forces. Although there is limited evidence of a shift in its nuclear strategy, China is changing its strategic posture to ensure its second-strike capability, including by relying on advanced conventional weapons (e.g., counterspace capabilities, cyber weapons, and electronic warfare) that can target U.S. missile defense. The dynamics of a nuclear-conventional entangled security dilemma may weaken arms race stability.

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

Most public discussion this winter reflects a conviction that Ukraine must — and can — win a decisive victory. But what constitutes a win against a country such as Russia? As we consider the road ahead, we cannot escape the brute fact that Putin commands an arsenal of roughly 6,000 nuclear weapons that could kill us all.

Stephen Walt explains why Putin understood that Ukraine's fate was more important to Russia than it was to 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 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.

The collective West is right to take Putin’s nuclear threats seriously, but efforts to dissuade him require the pro-active involvement of China and India.
