Provides a timely and authoritative analysis of the Cooperative Threat Reduction program. The quest to limit nuclear weapons was a notable feature of the U.S.-Soviet relationship during the Cold War. Following the collapse of the Soviet Union, in what history may come to judge as the Clinton administration’s greatest foreign-policy achievement, an agreement was reached with key former Soviet republics to eliminate their nuclear weapons. Ellis provides a timely and authoritative analysis of the Cooperative Threat Reduction (CTR) program, which removed nuclear arsenals equivalent to the combined stockpiles of Britain, France, and China, and ultimately made a significant contribution to U.S. national security at a relatively small cost. In a fascinating examination of the interplay of domestic and foreign policy, Ellis traces the debates within Congress and the foreign policy establlshment, as well as the situation on the ground in Ukraine, Byelorus, and Kazakstan, and he details the implementation of the CRT program. He concludes with a look at the current challenges, especially the thousands of non-strategic nuclear warheads still in Russian possession, and prospects of ongoing CRT efforts.
