The Allies claimed victory at the end of the Second World War, but the United States' invention of the atomic bomb and its replication by the Soviet Union posed new dangers for all nations. In Peace Prepared examines what Canada's Cold War Army did to prepare for war – and why and how it did it.

Although a Third World War never happened, army officers supported by a large civilian defence workforce of scientists, engineers, and designers responded aggressively to the challenges presented by the possibility of nuclear attack. Through innovation and adaptation, they developed a collaborative and systematic approach to problem solving that not only played a significant role in the evolution of Canada's national force but also shaped how armies in the Western Alliance related to one another during the Cold War and beyond.
