Kinda, but we achieve Flawless Victory when they get their paws on Pakistan's unsecured nukes and realize CONPLAN Glass Parking Lot (preferrably with significant attrition to their own forces, an option they don't seem to have an issue with). But don't worry, somehow that will be our fault.
On a more serious note, I find it interesting that they're interested in Af-Pak region when their stated objective is on the other side of Iran. I wonder (just musing) if a) these are groups that decided to declare for ISIS and ISIS is just letting them, or if b) they see this as a target of opportunity. Iran and Central Asia are pretty well locked down on anything ideologically and politically opposed to their governments and ISIS has mostly ignored the region and
told local supporters their to fight in Syria instead
