What was the outcome of the atomic bombing of hiroshima?
The bombing destroyed Hiroshima, killing the majority of its
populace and ending its contribution to the Japanese war effort.
However, as foreseen by the US, the bombing did not bring immediate
Japanese capitulation. Although the attack was unprecedented in the
scope of devastation, it was not immediately clear if the US claims
about it were factual. The leaders of Japan were much more
thoroughly awed when a second city, Nagasaki, was similarly
destroyed 3 days later. Within a week they had sued for peace, with
their Emperor himself declaring that the Japanese faced utter
annihilation unless they surrendered. (To his military, he instead
stressed that Japan could not logistically counter the threat posed
by the Soviet invasion of Manchuria.)
In the longer scale, the bombings set the stage for the Cold War
nuclear stockpiles by the US and Russia, notable for the fact that
they could never be used with impunity.
