While I believe Saddam at least had WMD until recently, I don't accept the presence of chemical suits as the smoking gun. I dont' think mounting casualty will cause quick over-turn of public opinion. It's just my hunch that people are able to stomach lots of war dead as long as they think they are doing a necessary thing. I think it's possible Saddam may eventually provide some support for anti-US terrorist, but I haven't seen any evidence to be positive. Besides, if Saddam wish to stay in power, wouldn't it be counter-productive to yank the tail of the bull?
