Joe is defending Bush Sr. over the first Gulf war where he left Saddam in power to run his scams. He is not defending Bush Jr. over the second gulf war where the socialist money tree (food for oil, weapons for oil, yellowcake uranium for oil....) was disrupted. That war hurt the international criminals and they are still reacting to the loss of income and send out the demorats chanting "Bush Lied, the Money Cow Died!".
I don't think so. Bush 1 went after Hussein because they invaded Kuwait. It was this president who used the WMD argument. Besides the question that elicited this answer was about why he wanted to work for Kerry.
