He's not a pussy, the flak he's gotten from other US citizens for his stance was and is pretty brutal. o, if he really was a pussy he would have been much better off going along with the flow...his position takes balls, too.
Anyway, the point is that it's pointless to keep on killing. The guy kills your son, you kill the guy, the guy's son kills you. Etc. You're welcome to go to Iraq and take revenge of course, but I think the most likely outcome is that you'd get killed yourself...so not exactly a big "woohoo!".
I'm not saying I wouldn't be pissed off, but I do respect the guy for being calm enough not to revert to blind revenge. And that he sees that Al Zarqawi isn't the only terrorist here.
