Answer
During the Cold War in Europe (1946-1953), the Soviet Union formed the communist Eastern Bloc, enforced the Berlin Blockade, created the Warsaw Pact, and divided Germany into four sectors. The United States responded by announcing the Truman Plan and forming the North Atlantic Treaty Organization. German citizens voted to reunite East and West Germany, and the U.S. and Great Britain airlifted supplies into West Berlin. The U.S. also sent troops into Eastern Europe.
