The A Bomb sure saved a lot of lives. I hate to think about the bloodbath if we'd had to invade the Japanese mainland.
In August '45 my dad had returned from Europe with the 20th Armored Division, was on a 30-day furlough, and then was to ship out for the Pacific. The 20th was scheduled to be in the first wave of the invasion of Tokyo Bay in March '46, and 100% casualties were expected.
