Either inform yourself or stop stereotyping people like its the 1960s. The terrorism problem originated from the military who decided to use FATA for its strategic gains. Gilgit baltistan you see today is because of Pashtuns. They fought for it. They were used again during the afghan jihad war in the 80s.
There are countless similar militant organizations propped up by the military who are largely dominated by Punjabis. Jaish e mohammad , Sipah e sahaba , Lashkar e Jhangvi etc etc all deadly militant organizations who have nothing to do with pashtuns.
FATA has been misused by the establishement. Ignored and left undeveloped for decades. On top of that the corrupt generals let US drop drone strikes on them. What do you want them to do? Thousands of missing people , extra judicial killing and what not.
If you want to end all this the place to start is GHQ. Clean that corrupt building so that they dont use people as props in the future.
