Abstract
The strategic environment underlying international policy responses to the proliferation of nuclear, biological and chemical weapons (NBC) has undergone dramatic and rapid transformation since 1990. This process was catalyzed by the dissolution of the Soviet Union and more recently by the terrorist attacks of 11 September 2001. The threat of proliferation has emerged from the Cold War era as a multidimensional threat involving multiple and distinct classes of weapons (nuclear, biological and chemical weapons as well as radiological devices), increasing access to dual-use technology and materials, exponential advances in science and technology and greater numbers of actors (proliferating states and nonstate actors). Accordingly, the new dimensions of the proliferation threat require diverse and multi-faceted international responses, i.e. a comprehensive strategy at the global, national and sub-national levels.
