"This March, 2001 Iraqi memo and Mohammed Atta's reputed trip to Prague in April, 2001, keep bouncing around in my head. If it can be demonstrated that Saddam's regime had advanced knowledge of 9/11, and was in favor of it, game over."
You are right, and also link it to the translation of the report of the Iraqi diplomat in Afghanistan who reported to his superiors, shortly after 9/11, that the USA had knowledge of Iraqi and al Qaida involvement in 9/11, and might use force against both.
I don't have a link for the translation, but it was widely reported, including on Free Republic.
<<>> But, the Libs claim that Atta was NEVER in Prague, despite the the confirmation from Czech(?) intelligence!
