The Baluchis overlap into Pakistan as well.
I believe that the delinquent states in the Middle East need to be dimembered.
Iraq into Shia, Sunni, Kurd; Iran into Kurd, Baluchi, Azeri, Sunni; and Pakistan itself into Baluchi, Pashtun, Sind etc.
In this way there would be a large number of smaller, ethnically and religiosly homogenous states, none of which would be large enough to be a threat to the region.
this is a good idea. or just seize the oil fields, let the savages duke it out on their own...but short of that, I like your plan.
