That fits right into the scheme of things:
1. U.N. fails to find "Weapons of Mass Destruction" So we'll have to go to war to route them out.
2. Oops! No weapons yet ... but Saddam's still an evil man with the potential to use WMD. "What about North Korea?". "Well, yeah. They're evil too but these guys look like those other evil bastards who did evil shit so we'll go after them first!". "Oh, OK" :/
3. Still no WMD, Mr. President!

"Patience. We'll find them once we crush those inf ... erm ... the oppostion forces who punish their gentle public so evilly." "What about other poor countries where that is the case?" "They don't have pet ... erm ... poisonous gases raining down on their people. Besides, we're fighting for the democracy of the people. That was our goal all along."
4. The war is over. Saddam no a qui. :/ WMD no a qui. :/ "Yeah, but we gave the power back to the peace loving people ... erm .. except for those looters." "I thought you had a plan to build a democracy." "We do ... that was part of a contigency plan. We also plan to contract big oil corporations to work on the oil rigs and provide jobs for the people (my personal conjecture towards a future quote :wink ) and stabalize things for those poor people."
5. "So you have no Saddam, no WMD, and no viable government at this point, right? In fact, it's almost if you went in there with no plan or concern to rebuild the country at all. You did; however, kick their ass and give a lucrative contract to a U.S. oil company."
6. Suprised? A show of hands please. :/
