If he's anything like the Arabs I new in college he spent the whole time hitting on one American woman who was entirely uninterested in him.
I think you hit the nail on the head. Proud, self-confident American women refused his Arab charms, and thus spurned, he turned his shame into rabid anti-Americanism and radical Islam. Makes sense to me!
He also had a thing about the sexuality of blacks, and that "jungle" music. An obsession that goes back to the Arabian Nights, though maybe not the music part.
