Former CIA Director George Tenet's new book, At the Center of the Storm, says "that al-Qaeda or groups affiliated with it have undertaken several other operations aimed at equaling or even surpassing the carnage of the Sept. 11, 2001, attacks" (April 30, 2007, Robert Windrem and Alex Johnson).
This and other disclosures are sobering and frightening and they lay out the scope of al-Qaeda's ambitions. The September 11, 2001 disaster is but a prelude of what they have planned.
