"Anybody visiting the Middle East in the last decade has had the experience: meeting the hoarse and aggressive person who first denies that Osama Bin Laden was responsible for the destruction of the World Trade Center and then proceeds to describe the attack as a justified vengeance for decades of American imperialism...professor Noam Chomsky decides to leave that central question open. We have no more reason to credit Osama Bin Laden's claim of responsibility, he states, than we would have to believe Chomsky's own claim to have won the Boston Marathon...Nothing serious," as Chomsky puts it, "has been provided since."..So is one to assume that he [Chomsky] has pored through the completed findings of the 9/11 Commission? Viewed any of the videos in which the 9/11 hijackers are seen in the company of Bin Laden and Ayman al-Zawahiri? Read the transcripts of the trial of Zacarias Moussaoui, the so-called "20th hijacker"? Followed the journalistic investigations of Lawrence Wright, Peter Bergen, or John Burns, to name only some of the more salient? Acquainted himself with the proceedings of associated and ancillary investigations into the bombing of the USS Cole or indeed the first attempt to bring down the Twin Towers in the 1990s?"
