The Threat of Weapons of Mass Destruction assembles research studies that analyze the weapons, efforts to control, and proliferation. Theses studies, reports, and analyses were conducted by governmental agencies, and private organizations under contract with the Federal government. They represent the most rigorous and authoritative research on global efforts to halt proliferation and reduce the threat. The documents in this collection are diverse in scope and emphasis. They dissect specific weapons, explore efforts to control proliferation, illuminate the psychology of WMD terrorism, trace the origins and development of international efforts to reduce WMDs, and address the formidable problem of developing feasible counter-measures and polices.
