which two countries were the leading powers during the cold war
Cold War 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.[1][2] Some major Cold War frontlines such as Vietnam, Indonesia, and the Congo were still Western colonies in 1947.
Soviet Union The Soviet Union suffered greatly in the war, losing around 27 million people.[45] Approximately 2.8 million Soviet POWs died of starvation, mistreatment, or executions in just eight months of 1941â€“42.[46] During the war, the Soviet Union together with the United States, the United Kingdom and China were considered as the Big Four of Allied powers in World War II [47] and later became the Four Policemen which was the foundation of the United Nations Security Council.[48] It emerged as a superpower in the post-war period. Once denied diplomatic recognition by the Western world, the Soviet Union had official relations with practically every nation by the late 1940s. A member of the United Nations at its foundation in 1945, the Soviet Union became one of the five permanent members of the United Nations Security Council, which gave it the right to veto any of its resolutions.
