So as @Lulldapull and @steppeWolff have educated us in the recent pastBut Waziristsn is in NWFP. Does NWFP too have links with Iran like Balochistan has?
Pashtuns (of NWFP, and Afghanistan too) are exerting an undue demographic and cultural change influence in Pakistan in non Pashtun areas.
Like Balochistan and Sindh, and I believe parts of southern Punjab too.
Balochistan is a huge pand area, and ethnic Baloch are very few. And are being replaced/displaced by Pashtuns from up north.
Its not necessarily all hostile either, cause the Pashtun and Baloch both being Iranic cultures. Annd both Sunni, there is significant amount of intermarrying as well. So land essentially changes hands with wedlock. Between both families and villages and tribes.
