[Machine Translation] The United States and the Soviet Union, which had cooperated with each other in World War II, came to confront each other from the standpoints of capitalism and socialism. The acquisition of nuclear weapons by both sides prevented them from launching a direct war, and a standoff ensued. This situation is called the Cold War. While the world was divided between the two superpowers, some countries declared that they belonged to neither. Eventually, with the end of the Cold War, the Soviet Union collapsed.
