Well, the Pope and the Archbishop of Canterbury have indicated pretty clearly that they are dead against this proposed war, for a start. I'd hazard a guess you'd find a lot more Christians against it than for it all over the world. (Including Iraq which has quite a sizeable Christian minority, who get treated far far better than would be the case in "our" ally Saudi Arabia, for example, where there is active persecution.)

But there seems to be a bunch of people in the States who like to use the label without ever having listened to the message. And no doubt there are people like that elsewhere, but they don't get so much attention paid to them. And I rather assume that there's a whole lot of Christians in the Sates who don't in any way go along with them either.
