Not so. George Bush left as Director on Jan 20, 1977; Turner left on Jan 20, 1981; and Gates left on Jan 20, 1993. Tenet was a Dem senate staffer. He ingratiated himeself with Bush 43 by naiming CIA Headquarters after his father.
Bush left he was not forced out, maybe preemptive but still. GWB did not appoint Tenet, and maybe Tenet did buy time by using 41, but so what? It still does not make him our responsibility and frankly with all the walls and misinformation and lack of decision making authority, I really can't get to mad at Tenet. He's a bureaucrat after all. LE is always reactive rather then proactive. It's the nature of the beast. Normal people have a hard time thinking like criminals and sociopaths.
