George Tenet: Fall Guy
George Tenet certainly shares some responsibility for the intelligence failures that occurred during his tenure as CIA director. The person in charge is ultimately responsible (a concept that seems to elude the current commander-in-chief).
But I really don't think it's fair for Tenet to be the administration's fall guy -- not when Dick Cheney made frequent trips to CIA headquarters to check out the intel relative to Iraq. The VP's presence and comments left no doubt among CIA staffers as to the conclusions he wanted them to reach. From what I've read, CIA analysts were intimidated -- precisely the result Cheney sought to achieve.
