In late February 2004, Christopher Carney made an astonishing discovery. Carney, a political science professor from Pennsylvania on leave to work at the Pentagon, was poring over a list of officers in Saddam Hussein's much-feared security force, the Fedayeen Saddam. One name stood out: Lieutenant Colonel Ahmed Hikmat Shakir.

If you were being honest, you would also note that the Weekly Standard - your source for the false statement made in your initial post - later retreated a bit and now take the rather Kerryesque position that they just don't know if the Shakir who was a Fedayeen officer and the Shakir with a similar - but not identical - name who attended the Kuala Lumpur meeting were the same man. Actually, most everyone now agrees that they are not the same person.
BUT, since you like to reference the 9-11 Commission for support, why don't we take a look at what they say about your claim?:
"Mihdhar was met at the Kuala Lumpur airport by Ahmed Hikmat Shakir, an Iraqi national. Reports that he was a lieutenant colonel in the Iraqi Fedayeen have turned out to be incorrect. They were based on a confusion of Shakir's identity with that of an Iraqi Fedayeen colonel with a similar name, who was later (in September 2001) in Iraq at the same time Shakir was in police custody in Qatar."
It is a shame I have to post stuff like this, because I know for a fact that you already knew it.
