The same holds for Pakistan as well, I am sure there would be many amongst the TTP who would like to reconcile and live normal lives. The incorrigible should be isolated and captured/killed especially their higher command. The locals should be provided with opportunities to study and work so as to reduce the recruitment pool available to them.
I agree that stability in Pakistan is directly proportional to the stability in Afghanistan, but as things stand now after the withdrawal of ISAF forces, taleban would have a strong presence in Afghanistan as the whole of Eastern Afghanistan is under their control, and even in the South (Helmand and Kandhar) they have a strong presence. And I dont know what Pakistan can do in this regard.
