I understand some good came out of it. It probably did end the war quicker. But, heaven's sake, friends, we could get any war over in a jiffy if we'd only nuke 'em again. So why don't we? Because we know we have to avoid doing so again, if at all possible. It's too horrific. (I'm not a peacenik. I'm trying to make an ethical argument here.)
Do you understand what the Japanese were like in WWII?
