The Eastern Bloc is a collective term for the former Communist countries in Central and Eastern Europe. This generally encompasses the Soviet Union and the countries of the Warsaw Pact. When Soviet Foreign Minister Vyacheslav Molotov expressed concern that the Yalta Agreement's wording might impede Stalin's plans in Central Europe, Stalin responded "Never mind. We'll do it our own way later." After Soviet forces remained in Eastern and Central European countries, with the beginnings of Communist puppet regimes installed in those countries, by falsified elections, Churchill referred to the region as being behind an "Iron Curtain" of control from Moscow.
