No, we kill them all and then at the same rate they recruit. This might go on for years. Obama will never this but the next President will have no choice.
As the article points out, correctly IMHO, ISIS is a Caliphate. Caliphates cannot exist like al Qaeda. They must hold territory. You must retake that territory and all the territory held by the Caliphate to destroy it. We have no choice. That is what we will do. The question is when and who will give the order. I'm betting it will be either Ted Cruz or Scott Walker.
Mouth . . . ears . . . amen
