This chapter explores the role and experience of Western Europe in the Cold War. It explains that Western Europe is not a precise political or geographical entity, and that its role in the Cold War can only be understood in the context of its changing internal dynamics and changing relationship with the United States, the Soviet Union, and countries of Eastern Europe. The chapter argues that Western Europe both shaped and was shaped by Cold War in a political, economic, military, cultural, and ideological sense, and also considers the German question, Franco-German rapprochement and European integration, and military aspects of the Western alliance.
