You have many misconceptions about Taliban.
Throughout this whole affair where US and Pakistan backstabbed them, and even now when each day our administrations talk from both sides of their mouth, Taliban have remained honest and true to their cause.
They are as much Pakistani as any of us, they came out of Deobandi madrassas and masajid under people like Maulana Sami ul Haq. They learned and embraced Islamic scholars like Maududi, Dr. Israr, Muftis Taqi and Rafi usmani, Tariq Jameel, while Pakistanis gave only a cursory glance to them.
All the victories which they have gained has been through their strength of will and self-won.
They have every right to rule Afghanistan. We should embrace our former brothers, as we were at fault for abandoning them.
They however have not sought any revenge against us and instead have been pressuring Washington to heed our interests better than our own governments.
It is they who have kicked out agents of India, Iran, Israel, and other nations from Afghanistan who meant to harm our state.
