American-British-Canadian Intelligence Relations, 1939-2000

This work considers, for the first time, the intelligence relationship between three important North Atlantic powers in the Twenty-first century, from WWII to post-Cold War. As demonstrated in the case studies in this volume, World War II cemented loose and often informal inter-allied agreements on security intelligence that had preceded it, and created new and important areas of close and formal co-operation in such areas as codebreaking and foreign intelligence.
