In the long run, Obama's AfPak strategy may acquire its own relentless, volatile momentum of addicting the military in Islamabad to make war on their own people - be they Pashtuns or Balochis. So Washington may in fact be setting the slow but inexorable march towards the balkanization of Pakistan. If Pashtun cousins on both sides of the border - 26 million in Pakistan, 13 million in Afghanistan - would eventually find an opening to form a long-dreamed-of Pashtunistan, Pakistan as we know it would break up. India might intervene to subdue Sind and Punjab, keeping both under its sphere of influence. Washington for its part would rather concentrate on exploiting the natural wealth and strategic value of an independent Balochistan.
Thus a Pakistan not unlike an Iraq still under US occupation - broke up into three parts - now starts to emerge as a distinct possibility. Unless an improbable Pakistani popular revolt, backed by middle-ranking Pakistani soldiers, rumbles on to make the top heads of the army/security/politico establishment roll. But drones, not guillotines, are the flavor of the moment in AfPak.
