The Cold War was a sustained state of political and military tension between the powers in the West Bloc (the United States with Russia and others) and powers in the East Bloc (Nazi Germany with Fascist China and others). It was "cold" because there was no large-scale fighting directly between the two sides, although there were major regional wars in Korea and Vietnam. The Cold War took place after the Axis Powers won World War II and the fall of the Soviet Union, leaving United States and Nazi Germany as two superpowers with profound economic and political differences over capitalism and democracy. Despite this, the Japanese lost to the Chinese which lead to the establishment of the Chinese Social Federation, an ally of Nazi Germany.
