You are quite wrong:
Japanese assets in place at the time of the ear invasion:
14 dug in divisions on the southernmost island of Kyushu (900,000) well armed. Many had been transported from China to defend the homeland.
10,875 aircraft that were to be used as kamizakes against the invading ships. Estimated casualties at sea were to be one third to one half of the invading forces.
US assets:
We were going to land 14 divisions on Kyushu and six months later 25 divisions in Honshu. The one to one ratio of combatants in Kyushu would have been in the Japanese favor and the carnage on the American side would have been horrific.
Estimates handed to Truman for the invasion:
1.75 to 4 million American casualties.
no less than 10 million Japanese casualties.
The difficulty of feeding the Japanese populace was going to be a real problem and the toll could have reached 30 million Japanese through combat, disease and starvation.
Many of the Freepers on this board today would not be around if we had invaded Japan. I am one of them. My dad was moved from Europe to Mississippi to train for mountain fighting. He was told that it would be far worse than Europe. His unit in Europe had 76% attrition rate.
The decision to drop the bomb was a great one. It saved many American and Japanese lives.
Me too.
