The hebrew word in the 10 commandments is murder, not kill. Many times God ordered his Chosen people to KILL men woman and children. And in Ecclesiastes it says there is a time to kill. Do you mind that Saddam kills his own people? It is just and noble to stop him, and his regime. It will involve killing, the murderers. And innocent people might get killed in the process. Innocent people are already being mass murdered by Saddam and his ethnic cleansing. So it is unjust to leave him alone. It is cruel and merciless to leave him in power. And anyone who wants to just let him alone, has not thought it over very well.
Oh, and by the way. George W. Bush is a Born Again believer in the Lord Jesus Christ and has confessed it many times on TV. Those around him, see him as a God fearing Christian. I think you have very poorly judged him by what you have read and heard about him from sources that want to debase this moral man. Or you judge from your lack of understanding of what is just about this war.
