"In December 2002, the President issued a National Security Presidential Directive on the National Strategy to Combat Weapons of Mass Destruction. It cites weapons of mass destruction (WMD) in the possession of hostile states and terrorists as one of the greatest security challenges facing the United States (U.S.) and commits the U.S. to pursue a comprehensive strategy to counter this threat. The Strategy calls on U.S. agencies to take full advantage of today's opportunities, including application of new technologies, increasing emphasis on intelligence collection and analysis, strengthening alliances, and establishing new partnerships with former adversaries. In April 2004, the President issued a National Security Presidential Directive on Biodefense for the 21st Century to guide efforts against biological weapons (BW) threats. In April 2005, the President issued a Directive on Domestic Nuclear Detection that provides guidance on global nuclear detection architecture. The CTR Program supports these Presidential Directives by pursuing four objectives: Objective 1: Dismantle FSU WMD and associated infrastructure, Objective 2: Consolidate and secure FSU WMD and related technology and materials, Objective 3: Increase transparency and encourage higher standards of conduct, and Objective 4: Support defense and military cooperation with the objective of preventing proliferation."
