Nuclear Issues

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

At a moment when arms control is deeply troubled and may be dying, two eminent scholars, Marc Trachtenberg and the late Robert Jervis, have taken a fresh look at the beginnings of strategic arms control fifty years after the signing in Moscow of the SALT I agreements in May of 1972. They do so from different vantage points, writes Steven E. Miller.

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 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. 

A nuclear explosion detonated anywhere by a terrorist group would be a global humanitarian, economic, and political catastrophe. The current COVID-19 pandemic reminds us not to ignore prevention of and preparation for low-probability, high-consequence disasters. For nuclear terrorism, while preparation is important, prevention must be the top priority. The most effective strategy for keeping nuclear weapons out of the hands of terrorists is to ensure that nuclear materials and facilities around the world have strong and sustainable security. Every president for more than two decades has made strengthening nuclear security around the globe a priority. This includes the Trump administration, whose 2018 Nuclear Posture Review states: “[n]uclear terrorism remains among the most significant threats to the security of the United States, allies, and partners.”

The Trump administration budget request for programs to reduce the dangers of nuclear theft and terrorism is too small to implement the ambitious approach that is needed. Congress should increase funding in this critical area; direct the administration to develop and implement a comprehensive plan for improving security for nuclear weapons and materials worldwide; and exert expanded oversight of this effort. This brief highlights the importance of ongoing nuclear security work; describes the evolving budget picture; and outlines recommendations for congressional action.

The Nuclear Nonproliferation Treaty (NPT), a bedrock of international security, had the 50-year anniversary of its signing in 2018. While the existence of the treaty has not been able to prevent a handful of states from seeking nuclear weapons, for half a century the NPT has promoted norms of nuclear nonproliferation and disarmament. Only nine states possess nuclear weapons today, far below the number predicted early in the nuclear age. Nonetheless, a second nuclear treaty, adopted in 2017, represents a significant and growing crack in the foundation of the NPT and suggests that relations among its members need to change if the treaty is going to survive another 50 years.
