I believe we did better with the 60+ cities we napalmed, before the two nukes we dropped in Japan.I take small exception to Fat Man. From an aiming point of about 30,000, the Bockscar crew missed Nagasaki by about 2 miles. That is a huge miss; and therefore hardly accurate. Still, it mangaged to kill 50,000 people, and it did convince the Japanese to give up the fight. So maybe good enough, really is. Full disclosure. My father was a 20 year old US Marine, veteran of Iwo JIma, Saipan, and Tinian, in Hawaii training for the invasion of Japan on 8/9/45. I'm cool with Truman's decision.
