Hmmm...just finishing Doug Feith's "War and Decision" and he appears to have a different story. He said that the CIA downplayed interpretation of evidence supporting an Iraq-Al Queda connection while overemphasizing WMD evidence which was slim.
BTW, WMD was only 1 of the many reasons that the US decided to invade Iraq. While proscribed weapons and programs were found, including everything saddam needed to restart his nuke program including intent, we did not find weapon stockpiles and percursors that he admitted having and were cataloged. The left needs this to be ignored, hence the mantra "No WMD" must be repeated often enough until it becomes the truth.
One of the administration's weaknesses is their unwillingness to confront this propaganda.
I am in the middle of Feith’s book myself.
You are right, the CIA isn’t portrayed as the sharpest knife in the drawer.
