The National Security Archive at The George Washington University is dedicated to providing key diplomatic documents that describe the world of political relationships and other key areas of government relations between the United States and other nations. This electronic briefing book released in December 2010 takes a look at the attempts by the Carter administration to roll back Pakistan's nuclear program in the late 1970s. These recently declassified U.S. government documents shed light on the "critical period when Washington discovered that Pakistan, a Nuclear Nonproliferation Treaty hold-out, had acquired key elements of a nuclear weapons capability." This collection contains 40 documents that highlight some of the behind-the-scenes negotiating that went on from 1978 to 1980. There's a brief synopsis of each document, and a fine introduction that provides some good context on this series of communiques and related exchanges.
