Problem is it's hard to know what is true.
One thing is obvious, Saddam and his regime lied a lot.
And most Iraqis were afraid for their life to speak the truth.
I think any country which has "minders" should cause people to pause for a bit and consider what this means.
Bush on other hand had no reason to say anything untrue.
Every Nation knew that Saddam wasn't complying with 1441, the only "question" was what to do about it.
If Blair was the president of US, I don't think he would have done anything different than Bush. Name any great president and I doubt any of them would have done things differently then what Bush did.
I think we will find the WMD and lot of other things in Iraq- though I don't know if WMD will end up being the most important thing. Obviously, WMD was Saddam's tarbaby. {And I'm glad he couldn't get away from it}
