Soon after America declared war on Japan, Germany also declared war on the United States. Thus causing a dilemma for the nation of the United States as a whole. If the United States had not quickly ended the war with Japan, it would have had difficulty supporting the Allied powers. However, Truman could have found another way to defeat Japan with a less violent tactic. While Truman had his reasons for using the bomb, there were people who agreed with him were the orthodox historians while the people who disagreed called revisionists. Truman had weighed all the possibilities and decided that using the bomb would be the most effective and quickest tactic. .

However, they did not know where and how the attack would occur. The surprise attack turned out to be a launch on the US naval base at Pearl Harbor on December 7, 1941. This angered the Americans to the point that they declared war on Japan the next day. Even though the United States favored neutrality, the United States was forced to enter the war. The Japanese government's progressive and violent actions against U.S. economic interests are what ultimately triggered the U.S. declaration of entry into war.
