Nuclear Issues

Nuclear security around the world has improved dramatically over the last three decades—which demonstrates that with focused leadership, major progress is possible. But important weaknesses remain, and the evolution of the threat remains unpredictable. The danger that terrorists could get and use a nuclear bomb, or sabotage a major nuclear facility, or spread dangerous radioactive material in a “dirty bomb,” remains too high. The United States and countries around the world need to join together and provide the leadership and resources needed to put global nuclear security on a sustained path of continuous improvement, in the never-ending search for excellence in performance.

This Policy Brief compares and contrasts the Trump administration’s 2018 Nuclear Posture Review with past reviews and its Obama predecessor. It concludes that this review offers a much harsher assessment of the security environment; it posits a more expansive role for nuclear weapons; and proposes a substantial de-emphasis on arms control.

Cooperation between U.S. and Russian nuclear scientists and engineers represents an important opportunity for rebuilding U.S.-Russian relations. The United States and Russia possess more than 90 percent of the world’s nuclear weapons, the world’s largest stocks of weapons-usable nuclear material, and the world’s largest nuclear complexes, giving them a special responsibility for nuclear security and preventing nuclear terrorism.

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.

In this new report, Preventing Nuclear Terrorism: Continuous Improvement or Dangerous Decline?, Matthew Bunn, Martin Malin, Nickolas Roth, and William Tobey provide a global reality check on nuclear security. They note that effective and sustainable nuclear security capable of addressing plausible threats is the single most effective chokepoint preventing terrorists from acquiring a nuclear weapon.

"One category of nuclear material that has not yet been adequately addressed throughout recent Nuclear Security Summits is military stockpiles.2 Instead, the Summit process has focused primarily on reducing the risk of civilian nuclear material theft..."

The abstracts in this booklet summarise the research presented at an academic symposium convened on the sidelines of the 2015 NPT Review Conference. As we write this, journalists and seasoned experts in the nuclear policy field have been speculating about the particularly difficult challenges facing the Review Conference this year. To address those challenges, we would urge all concerned to consider the ideas and analyses presented at this symposium. Experts would be hard-pressed to find a better collection of fresh ideas and approaches for assessing and strengthening the NPT.

Last fall, experts from around the world gathered to identify ways to strengthen nuclear security cooperation between the United States and Russia and the United States and China. In this Policy Brief, Nickolas Roth summarizes that conversation and provides policy recommendations based on it.

The Stanley Foundation convened a group of experts and policymakers from the United States and abroad to address these issues October 15–17, 2014, at its 55th annual Strategy for Peace Conference. The group discussed overcoming challenges to nuclear security cooperation faced by the United States, Russia, and China, and next steps in ensuring that countries put in place effective and sustainable nuclear security measures with strong security cultures. This policy memo offers highlights of the discussion and recommendations of roundtable participants.
