The U.S dropped the Fat man and little boy bomb over Hiroshima and Nagasaki in 1945. The decision under the administration of President Truman to drop the bomb had multiple perspectives or reasons. The first reason is that the United States wanted to elicit immediate surrender by Japanese. The second reason is that the U.S militarist and commanders were aware that Japan, if not stopped, would end in inflicting more casualties in Pacific war that would be up to 1 million as a rough guess. The third reason is that U.S atomic project Manhattan project decided to use A bomb with the consent of scientists of the project and Truman because they wanted to raise the dominance of U.S as an atomic power before soviet union that will sustain post-war.  Thus, the bomb dropping decision by the U.S was the only chance to end the war quickly. The Japanese emperor Hirohito on 15th August 1945 surrendered through radio broadcast. Explain how Cold War policy shaped the domestic life after World War II?The U.S and Soviets union were n competition by 1950s. After the world war II, the economic status of America became strong that resulted in a reduction of unemployment and investment in the education system. On the other hand, Americans lived in constant fear because of the Soviet Union nuclear bomb preparedness. Communities were advised to have air raid sirens installed, bomb shelters established by Americans, the interstate highway built in case of U.S invasion. The political people speeded buzzes in ordinary people to look for spies in nearby areas. The president Truman incorporated the strategy of containment to cope the paranoia created by the threat of communists in people. The cold war inculcated the seed of paranoia and fear among Americans.  Every person became an enemy of one another, and everyone started to feel at being the verge of destruction because of the Russian atomic threat. There was domestic fear built on every American with trembling thoughts of devastation that can wipe the existence at any time.ReferencesCliff Notes.
