It turned my stomach to see Colonel Tibbetts appear to get angry at the interviewer during one of the Hiroshima specials on the History Channel (or maybe Discovery Times Channel) today.
He angrily shot back at an unheard question, "You just can't understand that it saved more lives, American lives than it ever took of Japanese" or something to that effect. He said it with fire in his eyes and in such a way that it was clear he was pissed at the lefty doing the interview (i.e. he wasn't addressing the second-guessers at-large).
I just imagine that there was a string of questions about "conscience", "women and children", "100,000", etc. prior to the outburst. Whoever picked him for the job 60 years ago, damn sure picked the right guy.
That would be Uzal G. Ent
