Doubtful on any reconciliation with Dari speakers. Pakistan needs to look out for it's best interests which is supporting the majority Pakhtun population in Afghanistan.
Some time back people were talking about crushing the Taliban, where are those people now? I have always argued for reconciliation with the moderate elements and moving forward. The US is looking to exit the region, guess who will be back? :D
Bringing some Taliban in to the power set up in afghanistan is just common sense.
But Pakistan needs to have a good relationship with the Tajik, Uzbek and Hazara leadership. Isn't it ironic that our heroes like Ghazanavi and Ghori are Tajik, and there culture influence on Pakistan has been tremendous. We need to ditch this Pashtun centric policy. The Pashtuns are actually are a minority in Afghanistan, and not the majority, as that ISI agent Hamid Mir would have us think.
