Yup. Quite a racket, considering the low-tech conditions. (Bet they weren't virgins, though!)
Almost all closeup photographs of terrorists and clerics that I see in the media have one thing in common; they all look stoned out of their minds. The link between islam's fanatics and drugs is an ancient one. The Russians know this. It's a form of mind control. Once upon a time, as Marco Polo reported, the drug of choice was hemp, now it's opium.
