Asia & the Pacific

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.

This article reviews the motivations, strengths, and weaknesses of the Nuclear SecuritySummits (NSS), both procedurally and substantively.

The attacks in Brussels last month were a stark reminder of the terrorists’ resolve, and of our continued vulnerabilities, including in an area of paramount concern: nuclear security.

The attackers struck an airport and the subway, but some Belgian investigators believe they seemed to have fallen back on those targets because they felt the authorities closing in on them, and that their original plan may have been to strike a nuclear plant. A few months ago, during a raid in the apartment of a suspect linked to the November attacks in Paris, investigators found surveillance footage of a senior Belgian nuclear official. Belgian police are said to have connected two of the Brussels terrorists to that footage.

Matthew Bunn, Professor of Practice at Harvard Kennedy School and Co-Principal Investigator at the Belfer Center’s Project on Managing the Atom, sits down with Aroop Mukharji (@aroopmukharji) to talk about everything nuclear—from the nuclear football to the best way to prevent nuclear smuggling.

"World leaders face a stark choice at the final Nuclear Security Summit later this week: Will they commit to efforts that continue to improve security for nuclear weapons, fissile materials, and nuclear facilities, or will the 2016 summit be seen in retrospect as the point at which attention drifted elsewhere, and nuclear security stalled and began to decline? The answer will shape the chances that terrorist groups, including the Islamic State, could get their hands on the materials they need to build a crude nuclear bomb...."

Senior Fellow William Tobey testified on March 17, 2016, before the Senate Foreign Relations Committee on "Reviewing the Administration’s Nuclear Agenda."

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.

As the policy community prepares to assess an agreement between the U.S. and its P5+1 partners and Iran, Senate Foreign Relations Committee Chairman Bob Corker asked me to review the history of analogous agreements for lessons that illuminate the current challenge. In response to his assignment, I reviewed the seven decades of the nuclear era, during which the U.S. negotiated arms-control treaties, including the Non-Proliferation Treaty of 1968; strategic arms limitation talks and agreements from SALT to New Start; the North Korean accord of 1994; the agreements that helped eliminate nuclear weapons in Ukraine, Kazakhstan, and Belarus in the early 1990s; and the pact that eliminated the Libyan nuclear weapons program in 2003.

Among many lessons and clues from this instructive history, five stand out

"At the UN today, this year’s Review Conference will conclude its assessment of the performance of member-states that signed the Non-Proliferation Treaty, which became international law in 1970," Graham Allison writes. "Among the central issues the parties debated was whether the United States and Russia have been fulfilling their commitments under the treaty."

Allison points out that the U.S. arsenal has been cut by more than 80 percent by 1970, and the Soviet arsenal has been reduced proportionally. "The NPT and the norms it has established help ensure a more secure future for us all," he writes.
