Nuclear Issues

Following the breakdown of February’s Trump-Kim Summit in Hanoi, Belfer Center experts discussed the impact of the shortened summit. 

Ambassador and Belfer Center Senior Fellow Wendy R. Sherman, the former U.S. Undersecretary of State for Political Affairs, will lead HKS’s Center for Public Leadership and become a professor of the practice of public leadership in January. Sherman, who negotiated with the North Koreans and the Iranians on nuclear issues, is the author of Not for the Faint of Heart: Lessons in Courage, Power, and Persistence.

New sanctions imposed by the United Nations Security Council on September 11 in response to North Korea’s latest nuclear test are “not significant enough,” according to R. Nicholas Burns, an Atlantic Council board member who served as undersecretary of state for political affairs in the George W. Bush administration.

Sanctions must be part of a “patient long-term strategy” that includes deterrence, working closely with allies, and negotiations, said Burns, laying out the United States’ options for dealing with the North Korean crisis.

International Security is America’s leading journal of security affairs. 
IS was ranked first in impact factor for 2014 among 85 journals of international relations in the annual “Journal Citation Reports”® released by Thomson Reuters. International Security’s 2014 Impact Factor is the highest of any international relations journals.

The just-concluded fourth and final nuclear security summit saw some serious progress, but also some missed opportunities.

Matthew Bunn is a professor of practice at Harvard Kennedy School and co-principal investigator for the Belfer Center’s Project on Managing the Atom. Bunn’s research focus is on nuclear theft terrorism, nuclear proliferation, and innovation in energy technology. During the Clinton administration, Bunn served as an advisor to the White House Office of Science Technology Policy, where he played a major role in U.S. policies related to the control and disposition of weapons-usable nuclear materials in the United States and the former Soviet Union. We asked Bunn about the current crisis in U.S.-Russian relations and its impact on nuclear security.

The most significant achievement to emerge from the 2014 Nuclear Security Summit was a pledge by 35 countries to observe the terms of a joint agreement, known as Strengthening Nuclear Security Implementation. This document committed the signatories to incorporate the principles and guidelines of the International Atomic Energy Agency (IAEA) regarding nuclear security into their national laws, and to allow teams of international experts to periodically evaluate their security procedures. Promoted strongly by the chairs of all three nuclear summits—the United States, South Korea, and the Netherlands— the 2014 initiative is an important step towards creating a robust global security system designed to prevent nuclear materials from falling into the hands of terrorists.

Today, the United States and Japan announced that Japan would eliminate all the plutonium and highly-enriched uranium at its Fast Critical Assembly (FCA) at Tokai-mura.  This is a tremendous step forward for nuclear security; for terrorists, this would be some of the best material that exists in any non-nuclear-weapon state.  The material includes 331 kilograms of plutonium, most of it weapons-grade, and 214.5 kilograms of weapons-grade HEU.  (The FCA also includes over a ton of material just at the 20 percent U-235 mark that defines HEU.)   The weapons-grade HEU is enough for four simple terrorist “gun-type” bombs or a larger number of trickier-to-build implosion bombs.  The plutonium amounts to more than 40 bombs worth of material.

Fifty years ago this October, as the Cuban Missile Crisis intensified, the world stood   on the brink of a nuclear war. During 13 terrifying days in October 1962, people around the globe watched as President Kennedy and Soviet Premier Khrushchev searched for a way to move their countries—and the world—away from the nuclear cliff.

The Belfer Center commemorated the 50th anniversary of the Cuban Missile Crisis in October by encouraging fresh thinking on lessons learned from that dangerous confrontation—and how those lessons can be applied to crises encountered today.
