There are a number of them that he doesn't list:
- Leveraging a reliable, high level Iraqi defector, CIA man Tyler Drumheller told Bush, Cheney, and Rice that Iraq had no WMD program.
- Reporter Ron Suskind learned that "British intelligence agents met with the head of Iraqi intelligence in a secret location in Jordan, and that the Iraqi conveyed that there were no weapons of mass destruction in Iraq." The Iraqi was offered asylum and had no reason to lie. To cover up this debacle, Suskind's sources told him that the administration had a letter forged in the Iraqi defector's handwriting.
- Reporter James Risen reported that "some 30 family members of Iraqis made trips to their native country to contact Iraqi weapons scientists, and all of them reported that the [WMD] programs had been abandoned."
- On top of this you have circumstantial evidence involving the obvious pressure that the OVP and their neocon bureaucratic partners--armed with unvetted, shoddy intelligence--brought to bear on the intelligence community during the runup to the war.
- Then you have Cheney's office's obvious panic and sloppiness during the Plame affair. Why were they so concerned? (Of course the Washington press rarely, if ever, connected any of the above backstory to the Plame coverage when it was ongoing.)
