The Atomic Bomb and the End of the War in detail
By 1945, Germany had surrendered but Japan fought on. The USA developed the atomic bomb in the Manhattan Project, and the new president, Truman, decided to use it to avoid a costly invasion. On 6 August 1945, a bomb was dropped on Hiroshima, killing about 70,000 immediately, and on 9 August on Nagasaki. Japan surrendered on 15 August.
The decision is still debated: supporters argue that it saved lives by avoiding invasion, while critics say Japan was close to surrender and that it was a warning to the USSR. The bombs killed hundreds of thousands, with lasting effects from radiation, and ushered in the nuclear age and the Cold War arms race.
