The correct answer to this open question is the following.
During World War II, two big alliances were formed to engage in combat. On one side were the Allied Forces, formed by Great Britain, France, the United States, and the Soviet Union. On the other side, the Axis Powers, formed by Germany, Italy, and Japan. The war started after Adolph Hitler's troops invaded Poland in September 1939. The Axis Powers' countries represented authoritarian governments ruled by dictators in totalitarian states. The Allied Forces -except for the Soviet Union that was ruled by the dictator Joseph Stalin- were democratic countries that promoted trade and freedom.
