Bureau of International Security and Nonproliferation


Our Mission

Preventing the spread of WMD, delivery systems, and advanced conventional weapons capabilities — and rolling back such proliferation where it has already taken root — and protecting the United States’ critical and emerging technologies is the mission of the Bureau of International Security and Nonproliferation (ISN). In close collaboration with other bureaus within the State Department, other U.S. agencies, and a diverse range of international and non-governmental partners, ISN tracks, develops, and implements effective policy responses to proliferation threats and shapes the international security environment to prevent their recurrence.
