Investigation Plan During the time Franklin D. Roosevelt was in office, it was during World War II. Japan attacked the United States on December 7, 1941 and was known as Pearl Harbor. When this happened, Roosevelt did not hesitate to ask Congress to officially declare war on Japan. During the war, there was a proposal to land an atomic bomb on Hiroshima and Nagasaki to finalize the war. To this day there is still controversy as to whether that atomic bomb was actually necessary to end the war, due to the number of innocent casualties suffered by the Japanese. The purpose of this investigation is to answer the question: To what extent was the bombing of Hiroshima and Nagasaki necessary to end the war with Japan? To answer this question, the investigation will have to determine whether there was justification for this type of action conducted by the US government and its counter-government. The tactics of FDR, Truman, citizens, and historians will be evaluated. Books and speeches about Pearl Harbor and speeches by presidents will be provided to answer the investigation. Summary of the Evidence By the end of the war in 1944, the United States was realizing that it had to do something to truly finalize the war against Japan. They recognized that Japan was not as strong as them and surrendering was not an option for them because they always had that kind of motto that supported them being a tough nation. Although even the United States recognized that things were not going well for them as well. The United States, knowing what position they were in and without really thinking about it, decided to drop the atomic bombs anyway. On August 6, 1945, the atomic bomb was dropped on Hiroshima and Nagasaki. Many people died because of this, one estimate... half the paper... and Kyoko Selden.
