I think the US waited long enough. I like that you understand both sides of it Geiri... not many people here are capable of holding two simultaneous viewpoints and still retain the ability to function.
There is also the fact that it is hard to predict that actions of other world leaders, esp. the Saddam types, and a false move of a lack of a move thereof could possibly hurt your country very badly.
There are bad points to each side in the war, but partly circumstance and partly the way human nature influences those circumstances is why I chose to support the idea of what we're doing.. of course accidents happen and all that shit, and nobody likes it...
