While these days Brofessor sb reminds me of the band playing on the Titanic, I have to agree with him. There are far too many players who have a stake in Pak as a going concern.
1. The taller than mountain friend has invested over US$ 60 billion in Pak. Even a country as rich as it cant allow that much money to go down the drain. Pak is also useful as a cats paw in keeping local rival IND in check.
2. As the only state which is ideologically Islamic and is the only Islamic nuclear power, it has a certain brand equity among the brotherly Gulf states. Plus it is a source of manpower and if push comes to shove as a source of military manpower as well. While they may be indifferent to Pakistan being in a mess, there is no way the Keeper of the Two Holy Cities will allow Pak to vanish.
3. The Anglo American alliance too has large diplomatic and military investments in Pak.
4. Last but not the least, PAK or at least the cis Indus provinces are not a bunch of tribals or nomads; they are a settled society of producers who have lived in organised states for 5000 years. They have enough historical experience and ability to run a proper state.
