This Center for the Study of Weapons of Mass Destruction (WMD) case study examines the decision making process of the National Security Council for the U.S. withdrawal from the Antiballistic Missile Treaty (ABM Treaty). "The National Security Council (NSC) was unusually swift and effective in reaching and implementing the decision to withdraw from the ABM Treaty. The process was tightly controlled by the NSC staff, ensuring that the decision was close-hold, shared with only a small, trusted group of people, and implemented in a short time."
