Bad Asses of the World, Unite! You now have your own country, so to speak. Even if you’re not a devout Muslim, or not a Muslim at all, you now have a place to go where mayhem is sanctioned. That’s why so many disaffected youths—male and female—are making their way to Syria and ISIS, where they can be as bad as they want, just so long as it is in tune with what the self-professed Caliph, Abu-Bakr al-Baghdadi, permits.
And that’s where many of the new recruits will go astray. In the end, organized international mayhem is not as much fun as the local criminal kind. Instead of the cops, you have the Caliph’s masked minions; and now you can be blown to bits by bombers or Kurdish Peshmerga or (unless they feel disinclined) Iraqi armed forces. It’ll take them a while to discover that, because, as we know, bad asses are not known for thinking things through. And you can’t be all that spontaneous in an organizational context.
Oh, things will be gravy for a while, as you get your own Yazidi or other heretic girl to play house with, but eventually the pall descends; and you will be interviewed by Western news media as to why you deserted the cause.
