Funny how it's oh so imperative that ISIS be stopped, yet we're more than happy to leave the likes of, say, Boko Haram alone. Gee, it can't possibly be because ISIS is a threat to American oil imports while Boko Haram is not, right? Oh no, obviously it's because ISIS are such big meanies that it's simply out duty to continue white knighting our way through the Middle East. Yes, that's totally a believable story.
