Nonsense, like all the "BinLaden did it" lone-nut conspiracytheorists propound. All you have to believe is that the imperialist ruling class might have highly skilled, totally professional, experienced and expert villains who have, over generations, managed *from behind the scenes* the apparatuses of murder and mass-deception, known as CIA, Mossad, MI-5, et. al. Granting this, the strange "coincidence" of an organization organized under the auspices (and thereby totally open to penetration by CIA-Mossad agents of influence) of US Intelligence; carrying out a classical (see Conrad's "Secret Agent") terrorist provocation, that could succeed only through the immobilization of the entire US domestic air-defense system; and the subsequent cover-up of the catastrophic failure of US defenses (without even a scapegoat!), it doesn't take a Joe Leaphorn to realize that "there are no coincidences" here.
