Nuclear Issues

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.

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath. 

Rebecca Davis Gibbons and Stephen Herzog provide an update on current efforts to eliminate nuclear weapons. 

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.

The administration of President Donald J. Trump has consistently used fear of China to undermine nearly five decades of bipartisan consensus on US–Russian nuclear arms control. The negative consequences of these actions may last far beyond the Trump presidency. If generations of agreement between Democrats and Republicans on bilateral nuclear treaties with Russia erode, it will pose a significant setback to US national security and global stability. Future leaders may ultimately need to consider new approaches to nuclear risk reduction that preserve the benefits of the arms control regime.

The United States and Russia have about 91% of the world's nuclear warheads. And the arms control pact — the New START Treaty — between the two nations expires next year. Matthew Bunn spoke with The World's Marco Werman about the implications of the treaty.

The Bulletin of Atomic Scientists has published a document from the Pugwash Conference on Science and World Affairs concerning nuclear problems and tensions in the time of COVID-19. The document has been co-signed by a large number of Pugwash colleagues and personalities.

With the Russia investigation and impeachment behind him, President Trump finally may feel empowered to engage with Russian President Vladimir Putin and pursue an arms control deal.  

Putin is rumored to prefer focusing on foreign policy, where the Kremlin has proved itself to be a skilled player, while finding structural problems at home too boring to focus on. However, unless these are solved, he or his successor will continue to confront the reality that Russia remains too far behind the United States and China economically and demographically to be a true peer to these countries in the changing global order.
