After cooperating with the USSR (1939–41), the Nazi Germans under [[Adolf Hitler]] invaded in a war to the death. The USSR defeated the Nazis in [[World War II]] (1941–45), and took control of most of [[Central Europe]], turning formerly independent countries into Communist satellite states. It was the primary antagonist of the United States during the [[Cold War]] (1947-1989); it then collapsed because of American pressure and its own internal economic and social failures. At its height the USSR covered one-sixth of the earth's land area, stretching from [[Central Europe]] across [[Eastern Europe]] and northern Asia to the Pacific Ocean. Although Russia and most of Soviet republics are [[Western world]] countries, during the Soviet period, a war was declared on Christianity, the country wanted to cut its Western roots and create a brand new civilization, a communist utopia. | After cooperating with the USSR (1939–41), the Nazi Germans under [[Adolf Hitler]] invaded in a war to the death.
