One of the most effective ways to combat ISIS will be to attack their funding. More than anything, these Islamist groups depend on funding from outside sources to supply their war effort. Troops are fairly easy for them to get, and taking territory from them means little, since they they are supplied by outside sources. In short, it is difficult to run them out of manpower, and since they don’t actually live off the land they occupy, they can let go of captured territory without seriously hurting their war effort. The place to strike them is in their supply line. Cut the money, food, and arms that are flowing into their camps from other nations and Islamist groups, and their vital lifeline will be cut. With their lifeline cut, it will be only a brief matter of time before they suffocate.
