Dude, go easy on yourself.  ISIS is just a bunch of mercenaries paid for by the U.S. (with my tax dollars), and directed by mainly the U.S. and Israel.  Nothing could be more clear to to someone like myself who watched the money move around and the group form before the text string 'I-S-I-S' was even put out there in the mainstream media properties.

To be sure, a lot of the bullet-stopper pawns are radical Islamists, but they are inconsequential idiots pumped full of meth.  The same class of bottom dwellers can be found (and put to good use) in among any group of people.  The helicopters which swoop in to rescue the 'ISIS' leaders when Assad's forces get through the American defenses and overrun a base only pick up a couple of the leaders typically.  It's a fair bet that a lot of them have blond hair and blue eyes like your's truly.  Many of both those who do and those who do not have a yamaka to put on when they get home.
