Well you won't let go of Kashmir and want Afghanistan to let go of their land that was wrongfully made part of Pakistan? What right did Pakistan have to take Afghan land and make it part of Pakistan? What right did they have to include Balochistan in their land?
Even after this many years Afghan identity is well and truely alive among Pakistani Pashtuns. You think TTP is just a religious movement? You think PTM want to be part of Pakistan?
Kpk are not part of Afghanistan they were part of India and British India and before that sikh empire The durrand line was signed by your king in front of the British it's now an internationally recognised border by the un and intl community even india recognises the border and pakistan.
Balochistan khan of kalat the head of balochistan joined pakistan after seeing prophet muhammad saw in a dream .
Gwadar was bought from the sultan of Oman who had been possessing since the 1700s.
Also FYI majority of Pakistani pathans don't want to join afghanistan .
The problem is afghan infiltration and some elements amongst the tribes in fata whose lands were split by the British after the frontier wars and Afghan wars but that's a world wide phenomenon in many countries , the whole of the modern middle east was created by British but those countries have now accepted their borders .
As for borders why are you possessing northen Afghanistan , wakhan corridor , and central Afghanistan.
Northen Afghanistan was separate kingdoms of turkestan conquered by durranis and sameway hazarajat region conquered by durranis your king amir abdur rahman then forcibly settled pashtuns In these regions why are you occupying tajiks uzbek and hazara and pamiri land. Why are you occupying nuristan and laghman kunar you ethnically cleansed many of the original dardic and gujjar population and pashtunised .
Swat dir was all land owned by gujjars before yusufzais migrated because they were occupied by mughals babar attacked them and even married the yusufzai women . Who told yusufzai to migrate from kandahar to kabul and then take land of rajputs and gujjars whom were already muslim by then.
Even the afridi tribe majority of it is tirahi dards who were forcibly pashtunised .
Wakhan corridor was taken by British from gilgit baltistan and given to afghanistan as a buffer against Russia. Because the exact population lives in neighbouring gilgit baltistan the wakhis and a few Kyrgyzs
Also are you afghan supremicists claim to be jews that's what you wrote in your pata khazana which most scholars have viewed it as a forgery by namak harams.
