The Bureau of International Security and Nonproliferation (ISN) is responsible for managing a broad range of U.S. nonproliferation polices, programs, agreements, and initiatives. The proliferation of Weapons of Mass Destruction (WMD) and related materials, technologies, and expertise -- and the fact that terrorists are trying to acquire them -- is a preeminent challenge to American national security. Combating this threat through bilateral and multilateral diplomacy is one of the highest priorities of the Department of State. The ISN Bureau leads the Department’s efforts to prevent the spread of WMD -- whether nuclear, biological, chemical, or radiological -- and their delivery systems.

Assistant Secretary Dr. Christopher A. Ford leads the ISN bureau.

NPT Preparatory Committee 2018 in Geneva

From April 23-May 4, Assistant Secretary Dr. Christopher A. Ford headed the U.S. delegation for the Nuclear Non-Proliferation Treaty (NPT) Preparatory Committee meeting in Geneva, Switzerland.

At this year’s meeting, the United States continued to emphasize the common interests NPT States Parties share in the success of the Treaty and the central role of nonproliferation in achieving the full benefits of the Treaty. Preventing the spread of nuclear weapons is a direct and fundamental benefit of the NPT to all its Parties. An effective nonproliferation regime is a key element in building security conditions conducive to progress on nuclear disarmament. It also facilitates cooperation on peaceful uses of nuclear energy by building confidence that peaceful nuclear programs will not be misused or diverted to weapons.

As we approach the 50th anniversary of the NPT, the Preparatory Committee meeting was an opportunity for all NPT Parties to recommit themselves to preserving and expanding those benefits. More»
