Not only with the CIA, but why did the rest of the world, the UN, remain concerned regarding Iraq and WMD and carry on with the belief they had and continued to work on them? And shouldn't we be concerned that Iraq may have very well moved the weapons?
It's easy to "blame" the nameless spooks of the CIA. (previous post forgot: /sarcasm)
Saddam DID possess WMD, and Saddam used WMD.
