I would use every resource available to us, i would use the world banking system to strangulate them in terms of currency. I would try to get rid of any revenues they could derive from the oil and energy fields that they control. I would look at all the pathways, entrance and exit, like in Sinjar. You know, they took control of the supply routes first. And that made the subsequent capture easier. You know those typical, old fashioned but really effective military strategies -- they work.
