The break up of Pakistan is a topic thats doing the rounds in Washington, and I would think in New Delhi and Tel Aviv too. But what happens if Pakistan does not break up? Before oil runs out in the middle east, Shia Islam will be muted with the overthrow of the Ayatollahs as that is a much bigger priority for Israel as well as the US than breaking Pakistan is, at least going by current indicators and sentiments. Once Shia Islam is reigned in and suppressed, the idea of the Caliphate with KSA as the spiritual and political hub and Pakistan as the military leadership will emerge. Unchecked there could be major nuclear proliferation (if it has not already started) or at the very least Pakistan managed missile sites all around the caliphate. Pakistan's survival will determine the fate of a Wahabbi caliphate. The mind boggles at the possible outcomes.
