How did the World War II end?

World War II ended with the unconditional surrender of Germany of May 1945,  but both May 8 and May 9 are celebrated as Victory in Europe Day (or V-E Day). This double celebration occurs because the Germans surrendered to the Western Allies, including Britain and the U.S., on May 8, and a separate surrender took place on May 9 in Russia.

Cold War

The Cold War was a period of geopolitical tension between the Soviet Union with it's satellite states, and the United States with it's allies after World War II. The historiography of the conflict began between 1946 and 1947. The Cold War began to deescalate after the Revolutions of 1989. The collapse of the USSR in 1991 was the end of the Cold War. The term "cold" is used because there was no large-scale  fighting directly between the two sides, but they each supported major regional conflicts known as proxy wars. The conflict split the temporary wartime alliance against Nazi Germany and it's allies, leaving the USSR and the US as two superpowers with profound economic and political differences.
