RIP, sir. This is one area of historical revisionism that truly puts me into a rage, when you have people calling this a "war crime". It ended the war, and furthermore told a watching world not to mess with us. We got over half a century of respect out of that.
How many of us might not be here, if not for the actions of these men? I vividly remember my grandfather telling me stories about his time in the Navy during WWII. He was in Saipan, and the entire Pacific Fleet was preparing for an amphibious assault on mainland Japan that would have dwarfed the Normandy operation in scale. The War Department had estimated in excess of 1 million casualties. The two atomic bombs convinced Japan to surrender and that amphibious assault never occurred.
