Nuclear Issues

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

Following the news that the Trump administration plans to abandon the Intermediate-Range Nuclear Forces (INF) Treaty, signed in 1987 by Ronald Reagan and Mikhail Gorbachev, ten Belfer Center nuclear and U.S.-Russia relations experts offered their thoughts on the significance and consequences of this action.
 

Judging the Trump administration to be incapable of formulating a diplomatic campaign in support of one of its highest foreign policy priorities, John Bolton, a former U.S. ambassador to the United Nations, published an Iran deal exit strategy in the National Review on Monday. The document is less about why the United States should leave the Joint Comprehensive Plan of Action, and more about how to do so.

During the latter part of the Cold War, many strategists thought of nuclear deterrence and arms control as two of the most essential stabilizing elements of the same strategy in managing an adversarial relationship. The renewed crisis between the West (the United States and NATO member states) and Russia demonstrates how critical these elements are to the strategic nuclear relationship. As a result of recent setbacks between Washington and Moscow in the past few years, arms control has taken a back seat, and the risk of conflict due to miscalculation is the highest it has been since the 1980s.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.
