Not sure what to make of this

Jackie Mason & Raoul Felder at Jewish World Review have a startling claim about the events of Sept 11, 2001. If I saw this on a blog by itself I would be skeptical, but JWR is usually a reliable source.

I don't know if what they described is true or not, I sure didn't hear about anything like that happening in the US on that day and the article seems a little too close for calling "jihad" against all Muslims.

Comments and additional information to confirm or refute their allegations would be appreciated.
