President Harry Truman, the 33rd president of the United States, faced one of humanity's most powerful decisions. The atomic bomb was initially an idea created under the United States government. With a nuclear weapon like the atomic bomb came great responsibility. The idea of ​​how to use and regulate the bomb had not yet been implemented. Truman's decision to drop the atomic bomb changed the way Americans thought about war due to its traumatic effects. Under the administration of President Franklin D. Roosevelt the atomic bomb was being developed. After Roosevelt's death, his vice president Harry Truman was appointed president of the United States. Truman was never informed of the development of the bombs until an emergency cabinet meeting (Kuznick 9). Truman had to make the fateful decision whether the bomb should be dropped on Japan. With the idea of ​​going to war, Truman had to think about the lives of a thousand American soldiers. The American soldiers had begun using the island hopping method because the bomb was not available. The idea of ​​dropping a bomb was that the war itself could end in its first moments. The dropping of the atomic bomb could also justify the money spent on the Manhattan Project (Donohue 1). With a quote from Franklin D. Roosevelt “This will be a day that will live in infamy,” Pearl Harbor was a tragic day for Americans. The United States had lost many soldiers and said it would eventually retaliate. Alternatives to dropping the bomb were also discussed at the Interim Committee. The American government was trying to get a response to the invitation from the Japanese government. If the United States hadn't dropped the bomb and Operation Downfall ah... middle of paper... the Japanese people. Harry Truman's decision to drop the atomic bomb changed the way Americans thought about war because of the traumatic consequences. Works Cited Clancey Patrick ed.
