Defining
Jan. 1, 2012 - This revised Occasional Paper explores the issue of defining weapons of mass destruction with a focus on summarizing how the term has been used in disarmament negotiations, U.S. national security policy, Soviet and Russian military doctrine, and American political discourse. The paper identifies alternative definitions for WMD, addresses some of the key policy issues associated with different definitions, and proposes a definition appropriate for the Department of Defense.
