What were the physical and political effects of the dropping of the bomb on Hiroshima?

Answer 1

The political affects are that the Soviet Union and the United States entered into the Cold War. Additionally the United States had to develop policies to deal with this new kind of weapon. The Atomic Energy Commission was developed.

Answer 2

The physical effects were the near complete destruction of a large area, and death or injury to the populace, military and civilian alike. Practically all of Hiroshima was reduced to rubble, and a large part of Nagasaki.

The two bombs devastated lightly constructed residential buildings, and the debris fed the firestorm that followed. Many of those who were merely injured by the blast were trapped in the flames and died. Many survivors had been hit by wood and glass splinters from the pressure wave, and most had burns, some from where the thermal pulse had set fire to their clothes. The fallout from the blast killed more residents with radiation sickness, about which little was known even among doctors. Long term illness such as cancers afflicted a large percentage of the bomb victims.

The political effect was that the threat of more atomic bombs moved the Emperor, Hirohito, to press his generals for surrender to the Allies. To his soldiers, he stressed the military victories by the Soviets, which meant that the home islands faced invasion on two fronts.

Answer 3

The decision to drop the atomic bombs on Hiroshima and Nagasaki did work to have the Japanese surrender without appeasment.
