That’s actually how the mideival assassin cult started in the hills of present-day Iran. The dear leader invited initiates to a banquet, drugged the food, and then had them moved to a garden full of booze hot chicks and nubile young boys, let them do whatever they wanted for a day, drugged them, and brought them back to earth. He told them this was a taste of paradise, and they believed him, cheerfully dying for him.
Now do the same thing in reverse, have a provocateur give a would-be jihadi a bogus suicide vest, have it contain just enough explosives to knock him out, and bring him to the paradise of Helen Thomas, Janet Reno, Nancy Pelosi and Tiny Tim “virgins”. As they scream in agony, spray them with knock-out gas, bring them back down to “earth” and tell them that they’ve just tasted a piece of hell, and this is what awaits them if they don’t change their evil ways. Heck, convert them to scientology. Anything would be an improvement.
