First of all, let's be clear: the cold war is not a war! Although the Cold War was accompanied by several regional wars, such as the Soviet Union sending troops to Afghanistan and the United States fighting Vietnam, it was basically similar to World War II, but there were many differences.

Difference: 1' Cold War refers to the political and diplomatic confrontation, conflict and competition between the United States and the Soviet Union and its allies from 1945 to 1990. Because the Second World War has just ended, during this period, despite serious differences and conflicts, both sides tried their best to avoid the outbreak of a large-scale world war, and their confrontation was usually carried out by "cold" means such as local proxy war, scientific and technological arms race and diplomatic competition.

World War II is the second global war with the anti-fascist alliance and the anti-fascist forces all over the world as the other side.

Camp: The Cold War was a struggle between the Warsaw Pact led by the Soviet Union and NATO led by the United States.

World War II was a war between the Allied Powers and the Axis Powers.
