According to a 2006 book by journalist Bob Woodward, in the months before 9/11, CIA Director Tenet believes that Defense Secretary Rumsfeld is impeding the effort to develop a coherent strategy to capture or kill bin Laden. Rumsfeld questions al-Qaeda communications intercepts by the NSA and other other intelligence. [New York Times, 9/29/2006] Woodward writes in his book, “Could all this be a grand deception? Rumsfeld had asked. Perhaps it was a plan to measure US reactions and defenses. Tenet had the NSA review all the intercepts, and the agency concluded they were of genuine al-Qaeda communications.” As a result of these doubts, on June 30, 2001, a Senior Executive Intelligence Brief (SEIB) sent to top White House officials contains an article entitled, “Bin Laden Threats Are Real” (see June 30, 2001). [Woodward, 2006, pp. 50] However, apparently this does not quell the doubts. For instance, in mid-July 2001, Tenet is told that Deputy Defense Secretary and close Rumsfeld ally Paul Wolfowitz still doubts the surge of warnings and suggests that bin Laden may merely be trying to study US reactions to an attack threat (see Mid-July 2001).
