ISIS does not recognize borders. Would not surprise me if they went into Jordan. That would put them to the SE of Israel.
I expect the Jordanians will be tougher than the Iraqis.
Oh, I’m sure the thugs of ISIS will try whatever they can.
I hate to say mini-nuke because letting the genie out of the bottle once again it may never go back.
That being said, I don’t trust Pakistan any farther than I could throw them.
