Nuclear Issues

The Biden-Putin summit in Geneva did not disappoint the very low expectations set out for it. To move beyond symbolism and signaling, however, the Biden-Putin proclamation has to be translated into practical progress.

No great breakthroughs or dramatic developments were expected at the Biden-Putin summit, and none was achieved. But the message was clear: There is a new sheriff in town. Putin noticed, describing Biden as very different from Trump—experienced, balanced, and professional.

William d'Ambruoso explains why high-level engagement, built on a baseline of deterrence, lessens the chances of war and opens the way for future cooperation in North Korean–U.S. relations.

Every president serving in the last two decades has said that nuclear terrorism is a significant national security threat. Analysis of this threat has been, for good reason, mostly focused on foreign extremist groups, but recent events raise questions of whether there should be greater focus in the United States on far-right, domestic extremist threats. These extremists represent a unique danger because of their prevalence in federal institutions such as the military and the potential that they might infiltrate nuclear facilities, where they could access sensitive information and nuclear materials.

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. 

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.

Polls in the United States and nine allied countries in Europe and Asia show that public support for a nuclear test is very low. If the Trump administration conducts a test, then it shouldn't expect backing from Americans or its closest U.S. partners.

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.
