After Hiroshima and Nagasaki, the war was not over.
While Japan struggled to decide whether to surrender, the United States was already preparing another atomic strike. A third bomb, similar to the one dropped on Nagasaki, was nearing completion and could have been deployed within days.
Inside Japan, the situation was collapsing. Government leaders were divided. Some demanded surrender, while others insisted on fighting to the very end. As chaos spread, a group of military officers launched a desperate coup inside the Imperial Palace, attempting to seize control and prevent the Emperor’s surrender from being broadcast.
At the same time, American planners were preparing for multiple outcomes.
If Japan refused to surrender, Operation Downfall would begin, the largest invasion in human history. But there was another option: a prolonged nuclear campaign. U.S. officials discussed the possibility of dropping not just a third bomb, but several more in the following months.
Entire cities had already been selected as future targets.
Factories were producing enough material to sustain multiple atomic strikes. Military leaders believed it could take several bombs before Japan finally surrendered.
This is the story of the atomic bombs that never fell, and how close the world came to a far more devastating end to World War II.
