Nuclear Issues

David Kearn argues that the idea that the first use of nuclear weapons since 1945 would be by the United States in the defense of Taiwan against a conventional Chinese invasion would have significant, negative, and long-lasting, diplomatic ramifications. It is difficult to fathom the myriad potential consequences, but U.S. nuclear weapon use would almost certainly shatter the non-proliferation regime as a functioning entity, incentivize states (including China) to acquire or improve their existing nuclear arsenal, and damage America's standing globally.

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

David W. Kearn argues that deployment of nuclear weapons cannot rectify a perceived imbalance in conventional forces in the western Pacific.

Among the many issues surrounding China’s ongoing military modernization, perhaps none has been more dramatic than its nuclear weapons program. For decades, the Chinese government was content to maintain a comparatively small nuclear force. As recently as 2020, China’s arsenal was little changed from previous decades and amounted to some 220 weapons, around five to six percent of either the U.S. or Russian stockpiles of deployed and reserve warheads.

As the Biden administration and Congress struggle to get their heads around the challenge posed by China today, they should reflect on lessons learned in America’s success in winning the Cold War with the Soviet Union. Just because fundamental and irresolvable differences in values and interests compel the United States and China to be formidable rivals does not mean a hot war is a viable option.

Why do we think Vladimir Putin will not use “the bomb” when there is so much evidence that he will?

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.

Foreign Policy asked 12 experts to give us their views on the most important lessons of Russia’s war. Each writer is a prominent specialist in his or her field, and they answer a broad range of questions. Why did prevention and deterrence fail? What have we learned about strategy and technology on the battlefield? How do we deal with the return of nuclear threats? Some of these lessons are general, while others apply specifically to a potential conflict in Asia. 

To begin to appreciate what President Biden, Chairman of the Joint Chiefs of Staff Mark Milley, CIA Director Bill Burns, and National Security Advisor Jake Sullivan understand that most of the press and talking heads who have been discounting nuclear risks posed by the war in Ukraine don’t, it is useful to consider answers to seven questions.
