The CIA missed every large historical mess/situation in the last 20 years. If we're paying them to play spook while they miss the stuff that matters, we're fools. What about the Bay of Pigs, 9/11, breakup of the USSR - the Cole, Muslim militants and their reach - I'm sure the list is as long as the disasters. It's time for them to get off the stage. Let the military run intelligence. People with some ethics beyond their big fat egos... If the only thing they're good at is dirty tricks against Republicans, then they're a waste of taxpayer money.
Also, it's rarely pointed out that the CIA, including Valerie Plame's vaunted WMD unit, has totally botched virtually every significant development in WMD proliferation for decades. India and Pakistan going nuke, the whole Khan network including Libya and Iran and North Korea, everything about North Korea's nuke progress in the '90s, Iraq being within a year or less of having nukes at the time of the 1991 Gulf War, etc. etc. etc.
The CIA has been a total botch on WMD issues, so there was a lot more reason to be suspicious of than complacent about their pre-2003 assessments of Iraq. This is an important point that is almost never noticed. Every previous major WMD development for decades has been UNDER-estimated, not over-estimated, by our fabled CIA.
