On May 29, 2001, counterterrorism czar Richard “Clarke suggested to [National Security Advisor Condoleezza] Rice that she ask [CIA Director George] Tenet if there was more that could be done to preempt ‘a series of major terrorist attacks’ organized by [al Qaeda operations chief Abu] Zubayda. ‘When these attacks occur, as they likely will, we will wonder what more we could have done to stop them,’ Clarke wrote.”
