Millions of lives of many nations were saved with the first combat-deployments of nuclear weapons, over Imperial Japan, August, 1945.
The first deployment was 6 August over the city of Hiroshima. The bomber was a B-29 dubbed “Enola Gay” (for the commander’s mother).
Millions of lives of many nations, including Imperial Japan, would have been lost in an invasion of Imperial Japan. Such invasion would have been necessary had there been no nuclear bomb. That invasion, Operations Coronet and Olympic, already was-planned on 6 August, 1945.
The Imperial Japanese military would have fought with unforeseen-tenacity and courage, and in mass-suicide. Civilian deaths of such an invasion are incalculable.
Nonetheless, Allied victory of such an invasion would have been assured. But the human cost would have been on a drastic scale far-unforeseen. It would have exceeded by-far even the scale of loss at the horrible battle of Stalingrad.
And, also, it is assured, the nation-state of Japan no-longer would exist.
And, it is all but certain, I would not be here to write this.
