As one of the last things Carl Levin did before retiring, he released a letter he received from John Brennan demonstrating what a liar Dick Cheney is.

For years, Levin has been trying to get the CIA to declassify a March 13, 2003 cable assessing a source’s claim that Mohammed Atta met Iraqi intelligence officer Ahmad Samir al-Ani in Prague before 9/11, a purported meeting Cheney repeatedly used to insinuate a tie between Iraq and al Qaeda justified the war in Iraq. While Brennan still refuses to declassify the cable, but his letter does explain some of CIA’s assessment of that source.

On 13 March 2003, CIA headquarters received a communication from the field responding to a request that the field look into a single-source intelligence report indicating that Mohammed Atta met with former Iraqi intelligence officer al-Ani in Praque in April 20001. In that communication, the field expressed significant concern regarding the possibility of an official public statement by the United States Government indicating that such a meeting took place. The communication noted that information received after the single-source report raised serious doubts about that report’s accuracy.

The context — and CIA’s long refusal to declassify the cable — suggests that the source was yet another planted lead designed to justify the war, a last ditch attempt to create a tie between Iraq and al Qaeda that did not exist.

Brennan’s letter goes on to quote on line from the report.

The field added that, to its knowledge, “there is not one USG [counterterrorism] or FBI expert that … has said they have evidence of ‘know’ that [Atta] was indeed [in Prague]. In fact, the analysis has been quite the opposite. [brackets original]

Four days after this report, Cheney fought mightily to make the Atta claim once more, just before the attack, even though the entire intelligence community thought the claim was not credible.

I raise all this when I should instead be talking about the torture report because it gets to the point I made here, which I keep making in every radio appearance I do on the torture report.

This all was about exploitation, not intelligence. And for over a year, Dick Cheney’s goal for exploitation was to create a fraudulent case for the Iraq war, whether via torture or dubious single source claims in Prague. As Cheney complains that the torture report (which reported on the anal rape done in the guise of rectal rehydration done on his order) is “full of crap,” we should never forget that one end result of this was the disastrous Iraq war.
