Yes, I would argue that all of the countless civilians ( and the even more millions of their ancestors ) who did not die, because the USA did not have to invade Japan, would have considered that approach to be far more humane. Sparing lives is considered to be more humane than killing a far greater number of people.
Face it: Your course would have been the much bloodier and murderous choice for President Truman to have made. And by the way, most historical accounts put Japanese civilian casualties for the war at less than 600,000. In contrast, in the case of Nazi Germany ( which was invaded ) civilian deaths are estimated to have been around 1,700,000, almost 3 times that. Only a little more than 400,000 civilians are estimated to have been killed by the Allied Bombing campaign against Germany. Russia and China ( which were both invaded ) had by far the highest civilian deaths recorded in the war.
As far as the Third Reich goes, what exactly is the analogy that you are trying to make? You don't explain it. It would appear that you are comparing America's firebombing of Tokyo to the Nazi Concentration Camps. If that is the case, then you are well beyond my ability to adequately describe your thinking.
