Interesting reading...one response at the blog cites a Computerworld article, of all things...:
Vince Cannistraro, former chief of operations at the CIA's Counterterrorism Center...knew Clarke during his tenure as deputy chief of intelligence and research at the National Security Council, where Clarke "often came up with questionable proposals for covert action."
"Questionable proposals for covert action" neatly illustrated by this bit of lunacy even before before Clarke went to the NSC:
In 1986, as a State Department bureaucrat with pull, (Clarke) came up with a plan to battle terrorism and subvert Muammar Qaddafi by having SR-71s produce sonic booms over Libya. This was to be accompanied by rafts washing onto the sands of Tripoli, the aim of which was to create the illusion of a coming attack. When this nonsense was revealed, it created embarrassment for the Reagan administration and was buried."--George Smith, "Richard Clarke's Legacy of Miscalculation", SecurityFocus.com, Feb. 17, 2003
