During the World War II, based on reports of the US media, the US planned to attack Japan with 12 more nuclear bombs. The only thing that saved Japan from the next attack was their surrender.
Hiroshima and Nagasaki were struck by two nuclear bombs in WWII.
According to documents from the US military archives, which were revealed at a 70th anniversary of the bombings on August 6, Washington planned to hit Japan with another 12 nuclear strikes if they did not surrender.
Possible targets were Kyoto, Yokohama, Kokura, Niigata and Tokyo.
The US chose cities which weren’t previously bombed in order to test the full effect of their nuclear strikes.
US B-29 bomber hit the Japanese city of Hiroshima with an atomic bomb on August 6, 1945. This day, 140,000 people were killed. The city of Nagasaki was bombed on August 6, 1945 and 70,000 people were killed during this second attack.
