http://www.whitehouse.gov/news/releases/2002/10/2002; every once in a while, when the howls that Bush lied about WMD and got us into the Iraq war expunge the memory of what he was actually saying at the time, I go back to the speech he gave in Cincinnati the week before asking for congressional authorization. Re: nuclear weapons: "we don't know and that's the problem." Re: could things be worse after Sadaam taken out :"They could hardly be worse." I know people will immediately howl that they are worse. Worse than a terror regime perpetuating itself for decades? Was US worse off for having fought a relatively brief, bloody civil war or for centuries of allowing human beings to be kept as slaves? History and 90+% of Americans have reached the conclusion Lincoln was right.
Actually, that's the main problem: why in the hell did we invade Iraq without knowing that there were WMDs??? What a colossal blunder. We'll be paying for this error for years to come (both Republicans and America).
I certainly do not believe that Bush lied about WMD. He may have been misled by bad intel into a bad war. He may also have made a bad decision about what we do in cases where "we don't know."
It's a pretty costly thing to start a war and find out you were wrong.
