Nuclear Issues

Stephen Walt argues that the ultimate goal should be conflict resolution in Ukraine—not just an end to the fighting but a political arrangement that makes a resumption of war later on less likely.

While China is building nuclear reactors faster than any other country in the world, major constraints may limit nuclear energy’s ability to grow to the scale of hundreds of gigawatts that would be required for it to play a major part in decarbonizing China’s energy system. This chapter explores the major constraints on, and risks of, large-scale nuclear energy growth in China, and how both new policies and new technologies might address them. It focuses particularly on the two biggest constraints – economics and siting. Substantial government policies to support nuclear power and advanced reactor systems designed to address some of the key constraints are both likely to be needed for nuclear to have a chance of playing a major role in decarbonizing China’s energy system; nuclear energy’s role may be bigger in the second half of this century than in the first half.

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.

The existing global political-economic order has been ruptured by the rise of China, a broad backlash against globalization, uncertainties about the U.S. commitment to a rules-based system, and most recently, the Covid-19 pandemic. What form(s) might a future world order take, and what principles should guide efforts to construct it? The Future World Order event series will address these questions by examining individual topics ranging from traditional security issues such as arms control to newer, relevant issues such as digital trade. Professors Dani Rodrik and  Stephen M. Walt will moderate individual sessions.

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.
