Former NSA director and soon-to-be CIA director Michael Hayden says that a program in which the NSA listens in on calls between the US and other countries without obtaining warrants would have prevented 9/11, had it been in place then. Hayden tells a Senate hearing discussing his confirmation as CIA director, “Had this been in place prior to the attacks, the two hijackers who were in San Diego, Khalid Almihdhar and Nawaf Alhazmi, almost certainly would have been identified as who they were, what they were, and most importantly, where they were.” Hayden also says, “I can demonstrate in closed session how the physics and the math would work.” [US Congress, 5/18/2006 ] However, the NSA actually intercepted the calls between Alhazmi and Almihdhar in the US and an al-Qaeda communications hub in Yemen (see Early 2000-Summer 2001), which it knew had been in contact with Osama bin Laden (see November 1996-Late August 1998) and was also involved in the East African embassy bombings (see August 4-25, 1998) and the attack on the USS Cole (see Mid-August 1998-October 2000). Before 9/11, the NSA was entitled to pass on information about the calls to the FBI, but did not do so, even though the FBI had specifically asked for information about calls between the communications hub in Yemen and the US (see Late 1998 and (Spring 2000)). Various explanations for this failure are offered after 9/11 (see Summer 2002-Summer 2004 and March 15, 2004 and After).
