Specifically, the United States has defeated Japan twice in history. The first time was at the end of 18, when the United States launched a war of aggression against Japan. At that time, the shogunate was forced to sign a series of agreements, including opening up the economy and paying war reparations to the United States. Then at 186 1, Japan launched the famous Meiji Restoration in history. Japan began to learn a lot about education and science and technology in the western world. By the end of 19 and the beginning of the 20th century, Japan had become a world power. 194 1 year, a naval battle broke out in the Pacific between Japan and the United States. In the end, due to the failure of war strategy, Japan could not avoid the tragedy of fighting on two fronts. Not only did it not win the war, but the United States imposed an economic blockade on Japan, and Japan was completely isolated. Politically, the world anti-fascist alliance was established, and Japan has been fighting alone.
