Popular acceptance? No one I've ever seen or talked to has been for the Iraq war, in real life anyways.
I think it's hilarious that this guy actually believes terrorists have been hampered by our actions in Iraq. Sure a lot of insurgents have been killed, and some of them were foreign fundamentalists. But a lot of them were just pissed off Iraqis, just as I'd be pissed off if a foreign country tried to "liberate" me in my own nation. In fact killing them bolsters their recruitment and only earns us additional resentment.
