The Cold War dominated the world political arena for forty-five years. Focusing on the international system and on events in all parts of the globe, Melvyn P. Leffler and David S. Painter have brought together a truly international collection of articles that provide a fresh and comprehensive analysis of the origins of the Cold War. Moving beyond earlier controversies, this edited collection focuses on the interaction between geopolitics and threat perception, technology and strategy, ideology and social reconstruction, national economic reform and patterns of international trade, and decolonization and national liberation. The editors also consider how and why the Cold War spread from Europe to Asia, Africa, the Middle East and Latin America and how groups, classes and elites used the Cold War to further their own interests.
