It is no more a question of if, but when. My assessment is that there will be a Talibanised government in Pakistan within two to three years, after a prolonged civil war. Pakistan is currently a ferocious Doberman held on a leash by the US, and fed with exotic bones. It was meant to bark at and bite the USSR (and India) when the cold war was on, but the US realised recently that the dog has developed rabies and has become ferocious enough to bite the owner and the neighbours.
The US has no clue on what to do with its rabid canine. Running away from it is one option. The other is to try its best to force India, the eastern neighbour, to distract it with more bones like joint sovereignty of Jammu & Kashmir. The hope is that the dog will be distracted enough to allow the US to make its getaway from Afghanistan. Whatever the scenario, the net result will be an increasingly Talibanised Pakistan.
The problems faced by Pakistan are of its own making. It sees itself as a leader of the Islamic world. One Egyptian professor told me after visiting Pakistan in the 1990s that they gave him the impression that Islam was invented on August 14, 1947. During the recent Facebook prophet controversy, it was Pakistan which banned all internet media — something that wasn’t done by many countries even in the Middle East. Some sections of Pakistani society have embarked on a dangerous path of searching for pure Islam. First, they targeted Hindus and Christians using blasphemy laws. Then they targeted Ahmaddiyas (or Ahmadis) by declaring them to be non-Muslims.
