Guilt-ridden Westerners, of course, assume the answer lies somewhere in our foreign policy. There are lot of worn, hackneyed theories out there: they hate our relationship with Israel, they want us to leave their lands, they resent our interference in their politics, they detest how we pollute their culture.

These are all nonsense. Remember, most of these terrorists live in the West and seem to enjoy it. Some of them were even born here. Do they want U.S. and Western forces to leave Muslim lands? That would be a good explanation, except that young Muslims seem perfectly happy to follow the Crusaders home and settle in Brussels, Athens, and Paris.

Perhaps Islamic extremists resent our culture and its influence. Again, that would be an interesting idea if there weren’t so much evidence that they come to the West to bathe in our culture, to immerse themselves in it, to gorge on it. (The Paris attackers ran a notorious dive bar that was shut down for drug violations.)

These ardent young “Muslims” are excoriating the decadence of the West between bong hits while watching porn, listening to hip-hop, and playing video games on the Devil’s Box known as “a computer.” Europe is under siege, not from Hydra but from Ali G. Let’s face it: if the jihadis ever managed to bring our culture to an end, no one would miss it more than they would. They’d be heartbroken.
