Understanding the imaginary war offers a fresh interpretation of the Cold War as an imaginary war, a conflict that had imaginations of nuclear devastation as one of its main battlegrounds. The book includes survey chapters and case studies on Western Europe, the USSR, Japan and the USA. Looking at various strands of intellectual debate and at different media, from documentary film to fiction, the chapters demonstrate the difficulties to make the unthinkable and unimaginable - nuclear apocalypse - imaginable. The book will be required reading for everyone who wants to understand the cultural dynamics of the Cold War through the angle of its core ingredient, nuclear weapons.
