MAP 25.1 Cold War in Europe, 1955
This map vividly shows the Cold War division of Europe. The NATO countries (colored green) are allies of the United States; the Warsaw Pact countries (in purple) are allied to the USSR. At that point, West Germany had just been admitted to NATO, completing Europe’s stabilization into two rival camps. But Berlin remained divided, and one can see from its location deep in East Germany why the former capital was always a flash point in Cold War controversies.
