The Cold War split the temporary wartime alliance against Nazi Germany, leaving the Soviet Union and the United States as two superpowers with profound economic and political differences. The USSR was a Marxist -- Leninist state led by its Communist Party, which in turn was dominated by a leader with different titles over time, and a small committee called the Politburo. The Party controlled the press, the military, the economy and many organizations. It also controlled the other states in the Eastern Bloc, and funded Communist parties around the world, sometimes in competition with Communist China, particularly following the Sino-Soviet split of the 1960s. In opposition stood the capitalist West, led by the United States, a federal republic with a two-party presidential system. The First World nations of the Western Bloc were generally liberal democratic with a free press and independent organizations, but were economically and politically entwined with a network of banana republics and other authoritarian regimes throughout the Third World, most of which were the Western Bloc's former colonies. Some major Cold War frontlines such as Vietnam, Indonesia, and the Congo were still Western colonies in 1947.
