Well, we've accomplished our purpose, which is that if Saddam uses WMDs he's a liar, and deserving of any punishment we dole out.
Possible scenarios (I'm sure there are others):
1. We fight, Saddam doesn't use WMDs, and we prevail in 30 minutes or less.
2. We fight, Saddam does use WMD, everybody shuts their pie-holes for all eternity because we told you so, and we prevail in 30 minutes or less.
3. We stand down, and sometime in the future, Saddam or someone traceable to him uses WMDs on Americans or American allies, and we turn the entire Middle East into a giant chunk of glass.
Whatever. I'm sick to death of all the politically correct, bleeding heart, fat azz, do nothing, draft dodging, belly aching whiners that this country seems to turn out like so many jellybeans. I extend my full support to our elected officials, period. To the rest of the world, shame on you for forgetting 9/11 so quickly...
