Gaard,
I would still be in support of the war. The Liberation of an oppressed people from a genocidal tyrant is *always* worth doing, and in the long run, if we play our cards right, Iraq could become a nation that is free and productive and creative and a close ally, much like Japan has in the aftermath of WWII. It's not an entirely perfect analogy, but it's close enough for the purpose of the moral comparison.
Oh, and DealMonkey, yes, we're a nation of laws, and according to the law of the land, the PRESIDENT alone decides what other nations will be recognized by the US government as sovereign. The UN's opinion is still beneath the Constitution, and if wisdom prevails it *always* will remain so.
