Yes, although Congress in 1998 made it official US policy to use force against Iraq if they continued to interfere in the inspection process, the decision to use force against Iraq was wholly GWBs idea.
Also, you said the reasons kept shifting, Oklavol. Funny, they are pretty much laid out right there in October of 2002. The first reason being that Iraq was not in compliance with the resolutions that brought about the end of our efforts against Hussein in the early 90s.
You are great at revisionist history, Oklavol...that is if no one else is willing to dig up the research to prove you categorically wrong. Guess this wasn't your lucky day.
So we went to war for WMD"s. Then where are they?
Funny Saddam has all these stockpiles of WMD's and doesn't even use them on troops invading his country who are trying to hunt him down and kill him? It does sound odd.
I guess he would rather hide them to make Bush look back then to actually use them on enemy troops.
