To show the Japanese army that we have more firepower then them
United States
Pearl Harbor, Hawaii. They simultaneously bombed Army bases in Hawaii and Clark Field in the Philippines. They also bombed the US islands of Guam and Wake.
America dropped an atomic bomb on both Hiroshima and Nagasaki.
The Japanese government did not agree to surrender until August 14, 1945. The first A-Bomb was used against Hiroshima on August 6, 1945. Then the second A-Bomb was used against Nagasaki on August 9, 1945. After the second bomb, Japanese Emperor Hirohito broke with tradition & intervened to tell his government to accept the Unconditional Surrender to the US & its Allies. The Japanese government was controlled by the Army up until the Emperor intervened. Many in the Japanese government & Army wanted to continue the bloody war until the very bitter end (death of Japan's population).
Atom Bomb !! :)
Hiroshima and Nagasaki.
The USA dropped 2 Atomic Bombs on Japan, at Hiroshima, and at Nagasaki. The US used the Atomic bomb to weaken the Japanese military strength as the Japanese still had an army about 5 million strong, but after the strikes the Japanese surrendered unconditionally. The US dropped the bombs in preperation of the proposed invasion of the Japanese mainland. This opertion never happened. The US high command wanted to defeat Japan at the minimum cost of lives as the Japanese army was still strong.
The US drops the atomic bomb on two Japanese cities.
