God forbid that American foreign policy should be catered to Quebecois teens. When has the rest of the world ever really liked us, save for that bit after WWII? In and of itself, a positive world opinion is not worth changing foreign policy over. There's just nothing in it for us, and we can't be assured we'll get any more cooperation than we already have in our ventures. Our history alone is more than enough to counteract any goodwill we might garner, especially in those parts of the world with the most to gain from America as boogeyman (ie the entire Southern Hemisphere) and that's not even taking into account our support of Israel. How is it in our interest? Will a change in foreign policy prevent terrorism? Not drastically. As long as we remain the lone megapower, pressing up against the rest of the world, we can expect to be used as a catalyst for revolutionary or extremist sentiment whether or not we play nice. Depending on the goodwill of foreign populations isn't worth it. I think it's a little naive to think we can make headway in the muslim world specifically, because we've thrown our lot in with the jews, and they aren't going anywhere. Why try?
