What if the U.S. really found Weapons of Mass Destruction after the fall of Saddam? How would support for the war be different now? How would this have effected the 2008 election?
If Saddam had any usable chemical, bio or nuke weapons he would have used them. Lots of things would look different. (I have to say that if the monster of Bagdad had enough stuff to be a serious threat to anyone the chicken hawk in the White House would probably not have attacked)
And I have to remind you that everyone thought he had WMDs when we went in. Hell, the frontline troops were in NBC gear!
