In April 2004, the UN Security Council unanimously adopted resolution 1540, identifying the proliferation of nuclear, chemical and biological weapons and their means of delivery as a threat to international peace and security for the first time. The resolution legally obligates all Member States to make and enforce effective measures against the proliferation of such weapons and their means of delivery to non-state actors, and to combat illicit use of related materials. These measures will significantly strengthen the international efforts to prevent terrorists and proliferation networks from gaining access to WMD.

The United States is a depository nation for the Biological Weapons and Toxin Convention that bans the development, production and stockpiling of an entire category of weapons of mass destruction. Treaty efforts at annual Meeting of Experts and Meetings of States Parties, as well as pentannual Review Conferences have increasingly focused on disease surveillance capacity building, assistance in the event of a suspicious outbreak or alleged use of biological weapons (BW), biosafety, pathogen security, national implementation measures (including penal legislation), and issues related to "dual use" and the responsible conduct of the life sciences.

The Treaty on the Nonproliferation of Nuclear Weapons (NPT) comprises legally binding nonproliferation commitments and is the basis for international cooperation on stopping the spread of nuclear weapons. The President in Prague on April 5 said that the basic bargain at the core of the Treaty is sound: “countries with nuclear weapons will move towards disarmament; countries without nuclear weapons will not acquire them; and all countries can access peaceful nuclear energy.” More»
Fighting nuclear terrorism is a continuing national security priority. As President Obama said at the National Defense University on December 3, 2012: “There’s still much too much material -— nuclear, chemical, biological -— being stored without enough protection. There are still terrorists and criminal gangs doing everything they can to get their hands on it. And make no mistake, if they get it, they will use it; potentially killing hundreds of thousands of innocent people, perhaps triggering a global crisis. That’s why I continue to believe that nuclear terrorism remains one of the greatest threats to global security. That’s why working to prevent nuclear terrorism is going to remain one of my top national security priorities as long as I have the privilege of being President of the United States.” To learn about our programs go to the Office of Weapons of Mass Destruction Terrorism (WMDT) and the Office of Cooperative Threat Reduction (CTR).
Launched in Krakow, Poland in May 2003, the Proliferation Security Initiative (PSI) is a global framework of states that commit to disrupt transfers of weapons of mass destruction (WMD), their delivery systems, and related items to and from states and non-state actors of proliferation concern.

As of April 1, 2013, 102 states from all regions have endorsed these Principles and now participate in PSI. PSI celebrated its 10th anniversary in May 2013. More»
