Because World War II was launched by three fascist countries, Germany, Japan and Italy, and the aggression of these three countries caused public indignation in the international community, this war was called the anti-fascist war. As far as the purpose is concerned, fascist Germany is to conquer Europe and seize new living space. Another purpose is to avenge the nation and the winner of World War I .. But Japan, Italy and Germany have roughly the same purpose, but the targets of aggression are different. The Japanese want to control Chinese mainland and the whole Southeast Asia. Italy and Germany want North Africa together. The anti-fascist countries are mainly composed of the United States, Britain, China and the Soviet Union, and their purpose is obviously to defeat the fascist countries, safeguard world peace and ensure the progress of human civilization. The United States and the Soviet Union are also taking this opportunity to defeat the Axis countries, so that American democracy and capitalism can maintain their status as big countries in the mainstream world, thus gaining benefits and becoming the world's number one power.
