Series: Beyond Boundaries

The threat of nuclear conflict loomed menacingly over the world during the Cold War. Early warning of an attack was a crucial focus for military and political intelligence. Intelligence networks in Canada, the United States, and the United Kingdom came together, forming a tripartite intelligence relationship dedicated to indications that the Cold War would turn hot. The Next War is the first full account of the development of the allied indications network. Timothy Andrews Sayle dives deeply into recently declassified documents to explore this previously hidden history. He traces the decisions and choices made by intelligence organizations in Canada, United States, and United Kingdom to coordinate their assessments despite different, sometimes conflicting, national agendas, ideological positions, and levels of trust.

From early appreciations of the possibility of war with the Soviet Union to a formal agreement and communications network designed to link the intelligence establishments of Ottawa, London, and Washington, the tripartite intelligence relationship of the allied indications network established the basis for the close cooperation that continues to this day.

The Next War widens our understanding of Cold War intelligence history through exemplary scholarship and extensive foraging within the documentary record. With its descriptions of the evolution of national indications intelligence structures and the diplomacy and debates between allied capitals this book explains Canada's prominent role alongside its intelligence partners.
