D'Souza

The dust of those doomed towers had barely begun to settle before some Americans began asking themselves who, beyond Al Qaeda, was really responsible. Suspects included the Jews (as usual), the sinister Bush White House, the complacent Clinton White House and, in the view of Jerry Falwell, God.

In essence, argues Mr. D'Souza, it's the "depravity" (a word he savors with a little too much enthusiasm of our culture that has provoked a violent reaction among some fol lowers of Islam, and threatens to push large numbers of those he de scribes as "traditional" Muslims into the extremist camp.
