Pakistan is doomed anyway. They are dependent on IMF bailouts, are on the verge of a balance of payments crisis and not to mention creeping hyperinflation. Their own people are turning on their military due to rampant election fraud, cronyism and other factors. And those Afghans are going to end up in Taliban training camps and will get deployed in Pakhtunkhwa and Balochistan to wage insurgency. Pakistan is a banana republic and a nuclear weapons state with nearly every faucet of society controlled by their military generals. One of the worst combinations that the world has to offer.
