While I agree with Villain on some of this, the attacks Tuesday were the most devastating ever encountered in the world. If any side of any conflict were to launch an attack like that (in Ireland or Israel, for example) then I have no doubt those people would declare war and people would begin to pick sides. The same thing is happening in America. Maybe it's a scale issue. America is so much bigger than most countries (not population-wise, of course), that the attacks were bigger as a result. Car-bombs for small places, airplane-bombs for bigger. It's how to get the message across.
This isn't anti-american either. I'm very anti-terrorist. And while america seems to have had its hand in terrorism in the past (or perceived terrorism, usually broadcast as some kind of war effort), it doesn't mean that any nation deserves this kind of assault.
To Anti-Americans: lay off, they're going to learn their own lessons.
To Anti-Anti-Americans: lay off, you're going to get through this without throwing shit around.
Bah. I'm gonna hold off on getting my american citizenship now. No way I'm gonna fight a war for a country I wasn't even born in.
