I dunno - I think Baghdadi (caliph, not Baghdad, the city) is the real bad guy here. Take him out and the caliphate withers. Without territory and a figurehead / caliph ISIS falls apart. Of course a new caliph might step up and probably will but unless he's immediately accepted by all those who have pledged themselves to caliph Baghdadi then it becomes a power struggle.

I would thing our top priority would be to assassinate Baghdadi. Send in Bond.
