No, they know its not Al Qaeda.
What attack was Iraq going to do? Even if we had gone into Afghanistan in 2000, 9/11 would have happened. They were here for atleast 5 years, they didn't rely on anyone in Afghanistan to carry out the attack.
Of course, since I realise the real threat was not Iraq but several other countries - my head is in the sand. Believe whatever you want, Iraq had as much to do with terrorism as water has to do with fire.
Iraq harbored terrorists? Yeah, wasn't it a small camp of refugee terrorists? What about the biggest countries of them all? Syria? Saudi Arabia? Iraq was a mouse, these other countries are lions. "Base of operations"... thats funny, because that method was used by empire builders.
