There are other tribes living in between these areas geographically, for example, Pashtuns of Kabul and Nangarhar are divided by strips of Pashai and Tajik areas. There are tribes of Nooristanies and other minority groups living between Laghman and Northwest Pashtunkhwa. The same goes with Zabul, Kandahar, Helmand, Nimroz, Farah and all the way up to Herat, Ghor, and Badghish, these all have pockets of Baloch and Tajiks living amongst the Pashtuns in large numbers. How are you going to break Afghanistan and assume to label it a Pashtunistan? The minorities that are living under Afghanistan are united based on Afghanism not Pashtunism. They are not going to stay still and live in a state named after Pashtuns ONLY.
