After enduring the CIA's harshest interrogation methods and spending more than a year in the agency's secret prisons, Khalid Sheik Mohammed stood before U.S. intelligence officers in a makeshift lecture hall, leading what they called "terrorist tutorials." In 2005 and 2006, the bearded, pudgy man who calls himself the mastermind of the Sept. 11, 2001, attacks discussed a wide variety of subjects, including Greek philosophy and al-Qaeda dogma. In one instance, he scolded a listener for poor note-taking and his inability to recall details of an earlier lecture. Speaking in English, Mohammed "seemed to relish the opportunity, sometimes for hours on end, to discuss the inner workings of al-Qaeda and the group's plans, ideology and operatives," said one of two sources who described the sessions, speaking on the condition of anonymity because much information about detainee confinement remains classified. "He'd even use a chalkboard at times."
These scenes provide previously unpublicized details about the transformation of the man known to U.S. officials as KSM from an avowed and truculent enemy of the United States into what the CIA called its "preeminent source" on al-Qaeda. This reversal occurred after Mohammed was subjected to simulated drowning and prolonged sleep deprivation, among other harsh interrogation techniques. "KSM, an accomplished resistor, provided only a few intelligence reports prior to the use of the waterboard, and analysis of that information revealed that much of it was outdated, inaccurate or incomplete," according to newly unclassified portions of a 2004 report by the CIA's then-inspector general released Monday by the Justice Department.
The debate over the effectiveness of subjecting detainees to psychological and physical pressure is in some ways irresolvable, because it is impossible to know whether less coercive methods would have achieved the same result. But for defenders of waterboarding, the evidence is clear: Mohammed cooperated, and to an extraordinary extent, only when his spirit was broken in the month after his capture March 1, 2003, as the inspector general's report and other documents released this week indicate. Over a few weeks, he was subjected to an escalating series of coercive methods, culminating in 7 1/2 days of sleep deprivation, while diapered and shackled, and 183 instances of waterboarding. After the month-long torment, he was never waterboarded again. "What do you think changed KSM's mind?" one former senior intelligence official said this week after being asked about the effect of waterboarding. "Of course it began with that."
One former U.S. official with detailed knowledge of how the interrogations were carried out said Mohammed, like several other detainees, seemed to have decided that it was okay to stop resisting after he had endured a certain amount of pressure. "Once the harsher techniques were used on [detainees], they could be viewed as having done their duty to Islam or their cause, and their religious principles would ask no more of them," said the former official, who requested anonymity because the events are still classified. "After that point, they became compliant. Obviously, there was also an interest in being able to later say, 'I was tortured into cooperating.' "
Mohammed described plans to strike targets in Saudi Arabia, East Asia and the United States after the Sept. 11 attacks, including using a network of Pakistanis "to target gas stations, railroad tracks, and the Brooklyn bridge in New York." Cross-referencing material from different detainees, and leveraging information from one to extract more detail from another, the CIA and FBI went on to round up operatives both in the United States and abroad. "Detainees in mid-2003 helped us build a list of 70 individuals -- many of who we had never heard of before -- that al-Qaeda deemed suitable for Western operations," according to the CIA summary. Mohammed was an unparalleled source in deciphering al-Qaeda's strategic doctrine, key operatives and likely targets, the summary said, including describing in "considerable detail the traits and profiles" that al-Qaeda sought in Western operatives and how the terrorist organization might conduct surveillance in the United States.
