At least twenty countries-many of them hostile to the United States and its allies-have now or are seeking to develop the capability to produce nuclear, biological and/or chemical weapons of mass destruction and the means to deliver them. More than twelve countries have operational ballistic missiles, and others have programs to develop them. Weapons of mass destruction may directly threaten US forces in the field and, in a more perplexing way, threaten the effective force employment by requiring dispersal of those forces. Potential adversaries may use weapons of mass destruction to deter US power projection abroad. As President Clinton stated to 'If we do not stem the proliferation of the world's deadliest weapons, no democracy can feel secure.' Because of concern over this threat, the National Defense Authorization Act of 1994 (NDAA 94) required the establishment of an interagency review committee composed of representatives from the Departments of State, Defense, Energy, the Intelligence Community, the Joint Chiefs of Staff and the Arms Control Disarmament Agency and tasked the committee to report on nonproliferation and counterproliferation activities and programs. To ensure comprehensiveness, representatives of other departments and agencies were asked to participate. In accordance with NDAA 94, this report provides a top-down overview of existing, planned and proposed capabilities and technologies, as well as a description of priorities, programmatic options and other issues.
