Saddam murdered his own people by the hundreds of thousands. This is a fact. He was a bad guy, our sworn enemy, unstable and still seeking WMD's, and we removed him.
There are 100's of BAD dudes that kill their people. That has never been used as an excuse for pre-emptive war in Modern history , no wait i was wrong, the US did that in Panama also.
Where do you get off saying Sadam was Sworn Enemy ? He attacked Kuwait remember not the US. The US atatcked him with 30 other Nations, so no it was not Sadam vs the World. Perhaps Bin Laden can be disscribe that way now adays. Remember the US PUT Sadam in power and gave himhis bio weaps.
