Now, in your mind put that with the fact that Saddam manufactured and used, but would not document the destruction of terroristic WMD. I can think of no other reasons required to remove him from power.
Is it because it is a hard and dirty job and people are dying? They were before and they will be after, and even though it sucks, sometimes you just have to do it. This is one of those times, and you should be happy, and proud, that we are willing to make the sacrifices in the pursuit of being left the **** alone!
