The CIA warns the interagency Counterterrorism Security Group (CSG) that al-Qaeda members “believe the upcoming attack will be ‘spectacular,’ qualitatively different from anything they have done to date.” [9/11 Commission, 3/24/2004; 9/11 Commission, 7/24/2004, pp. 259] Counterterrorism “tsar” Richard Clarke, who leads the CSG, similarly warned the CSG of a “spectacular” al-Qaeda attack the day before (see July 5, 2001).
