That sounds correct to me. Palestinian Christians are sometimes opposed to Israel, which can come as a surprise to Americans accustomed to being sympathetic to Israel. Some of the older Arab terrorist organizations were socialist in foundation rather than Islamic and could easily have had 'Christian' members.

Radical Islamic terrorism grew out of different roots than the other groups, but may be making common cause or alliances of convenience.

In fact, the terrorists who pioneered skyjacking, and foreshadowed Semptember 11th, belonged to the PFLP, a Communist sect within the PLO, which as far as I know never had any connection to political Islam until its resurgence during the Al-Aqsa Intifada.

George Habash and Yasser Arafat were the role models of Osama Bin Laden, even if he refuses to concede this in public.
