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.

The 2016 nuclear security summit was a pivotal moment for the decades-long effort to secure nuclear material around the globe. More than 50 national leaders gathered in Washington for the last of four biennial meetings that have led to significant progress in strengthening measures to reduce the risk of nuclear theft.

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.

On April 28, the Project on Managing the Atom joined the James Martin Center for Nonproliferation Studies at the Middlebury Institute of International Studies at Monterey, The Netherlands government, and the United Nations Office for Disarmament Affairs (UNODA) in convening nuclear nonproliferation experts from around the world at the United Nations to participate in a Symposium on the 2015 Nonproliferation Treaty (NPT) Review Conference.

The ninth Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) will be held at the UN Headquarters in New York from April 27-May 22, 2015. This is the fourth such conference since the indefinite extension of the NPT in 1995. Participating governments will discuss nuclear disarmament, non-proliferation, and the peaceful use of nuclear energy with a view to arriving at consensus on a number of issues.

Nearly all of the 190 signatories to the Nuclear Non-Proliferation Treaty (NPT) agree that the forty-two-year-old treaty is fragile and in need of fundamental reform. But gaining consensus on how to fix the NPT will require reconciling the sharply differing views of nuclear weapon states and non-nuclear weapon states. Strengthening the international rules is increasingly important as dozens of countries, including some with unstable political environments, explore nuclear energy. The result is an ever-increasing distribution of this technology. In this paper, Steven E. Miller outlines the main points of contention within the NPT regime and identifies the issues that have made reform so difficult.
