The Japanese had done several things that the Americans weren’t happy with. The Americans wanted revenge for the humiliation by the bombing of Pearl Harbor. United States decided to use nuclear weapons as a revenge for the embarrassment of Pearl Harbor. The Japanese launched a sneak attack against the U.S. This wasn’t the first time Japan launched an attack. The Americans were also not happy with what the Japanese were planning. The Japanese were planning to make a bacterial bomb to spread a disease throughout the U.S. by experimenting on innocent chinese people. The Japanese experiments were awful they would cut open chinese people while still alive. They were also experimenting with rats to build the bacterial bomb.This tragic became known as the Nightmare in Manchuria or unit 731. After the bombs on Japan, Japan surrendered unconditionally and part of it was taking all documents from the experiments.The Japanese needed to be stopped.
