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.

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.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.

In this op-ed for The Conversation, Kalman Robertson writes that Iran agreed never to develop nuclear weapons when it signed the NPT in 1968. There's no ironclad method to prevent Iran from breaking its promise and developing nuclear weapons, but this new agreement builds in a number of strong protections. In conjunction with U.S. and allied intelligence capabilities, these rules mean even a sophisticated and carefully executed secret plan would carry a high risk of detection.

The Project on Managing the Atom offers fellowships for pre-doctoral, post-doctoral, and mid-career researchers for one year, with a possibility for renewal, in the stimulating environment of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. The online application for 2016-2017 fellowships opened December 15, 2015, and the application deadline is January 15, 2016. Recommendation letters are due by February 1, 2016.

To assist Members of Congress and observers in analyzing these issues and judging a potential comprehensive agreement, the Belfer Center prepared this brief to outline the key facets of sanctions against Iran. Written as an addendum to our April policy brief, ‘Decoding the Iran Nuclear Deal,’ this report is driven by the policy debate’s leading questions.

William H. Tobey, Matthew Bunn, and Nickolas Roth oppose proposed legislation that would prohibit funding for fixed radiation detectors to catch nuclear smugglers. They argue for a balanced program to defeat nuclear smuggling that includes strong security, effective law enforcement and intelligence work, and interdiction efforts and border controls backed by both fixed and mobile radiation detectors.
