Sorry but this is one of the most ill-informed post I have seen in a long while. And that is putting it kindly.
1) Paul Tibbets was a recipient of the Purple Heart among other decorations. He flew with the 8th and 15th Air Forces, and in fact as group commander, he led the first bombing mission of the the Mighty Eighth.
2) Perhaps it would be better if the secrets of the nucleus of atoms were not known to mankind. Maybe we would still be fighting large conventional wars killing millions. That is debatable But given the CONTEXT of the fanatical Bushido driven Japanese resistance and using previous battles in the Pacific culminating with Iwo Jima and Okinawa NO serious historian will argue that the use of these weapons DID NOT save millions of lives. The Japanese were going to use everyone, women and children too, in the defense of the mainland.
3) The last part of your sentence is just a big non sequitur.
