Nuclear Issues

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

Belfer Center experts on the U.S.-China relationship and Middle East issues shared thoughts on the significance of the unexpected Iran-Saudi Arabia agreement brokered by China. 

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.

Joseph Nye writes that Russian aggression and nuclear saber rattling have reminded us that the likelihood of nuclear war is a matter of both independent and interdependent probabilities. Paradoxically, reducing the probability of an all-out catastrophe requires that we learn to accept a certain degree of risk and uncertainty.

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.

Stephan Walt writes that Trump's foreign-policy instincts might be more sound—but he has forfeited the chance to lead.

Rebecca Davis Gibbons writes that having a full appreciation of the consequences of nuclear weapons and their place in society means learning from the stories of the survivors of Hiroshima and Nagasaki—but also from the stories from other survivors of nuclear explosions: those who lived and worked adjacent to testing sites in Algeria, French Polynesia, Australia, the United States, France, the Republic of the Marshall Islands, Western China, and Kazakhstan.

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

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.
