My Dad was steaming for the Japanese home islands aboard the carrier Ticonderoga. They were going to use navy personnel as infantry and he had been told he would be carrying a BAR because he was big and strong. If you remember, they expected to take a million casualties in that invasion. I likely am here and alive today BECAUSE they used the bomb. There are NO apologies in order.
I believe we would have had to fight twice in Japan, if not for the Bomb.
The first time to get rid of Tojo and Company.
The second time to stop a Communist takeover of Japan, because it would have been divided, just like Korea.
