Well, having flown close to the Iraq/Iran and Afghanistan/Pakistan "borders", and seen the non-existant barriers, it is obvious to me that until they are made secure against insurgency movement (which will never happen), no amount of military power, whether it is ground or air borne, will ever be effective.
At the moment we haven't even worked out the limits of the playing field and, even if we do know where the field extends beyond our lawful footprint, we don't have permission to send our team there.
We have no chance.
