The Bridge in the Parks: The Five Eyes and Cold War Counter-Intelligence

Established in the 1940s, the Five Eyes intelligence network consists of Australia, Britain, Canada, New Zealand, and the United States. The alliance was integral to shaping domestic and international security decisions during the Cold War, yet much of the intelligence history of these countries remains unknown. In The Bridge in the Parks, intelligence scholars from across the Five Eyes come together to present case studies detailing the varied successes and struggles their countries experienced in the world of Cold War counter-intelligence.

The case studies draw on newly declassified documents on a variety of topics, including civil liberties, agent handling, wiretapping, and international relations. Collectively, these studies highlight how Cold War intelligence history is more nuanced than it has often been portrayed – and much like in the world of intelligence, nothing is ever entirely as it seems.
