By that logic why discuss anything?
Discussing is one thing. Flying into a rage and banging out a screed on the internet is another.
Unfortunately the world isn't black and white. And war certainly isn't black and white. And analyzing a war from over half a century ago is certainly not black and white. If you have a forum consensus that knowing what we know now that action was wrong why beat us all over the head trying to get us to all froth at the mouth and call it a war crime? What are you hoping to accomplish?
Regardless of the merits of the actual topic, this type of "reasoning" is one of the worst forms of arguments out there. So bad that I could tell you're wrong just by reading this post and not taking in any of Al's.
