Actually this is not true. 1930 FCR law was in tribal areas till 2018. Study that law and ull realize why all that happened. The locals were never strong enough to deal with such groups, the locals also did inform about it but nothing was done. Its fault of state that after 70 yrs of Independence, they didnt abolish FCR. The tactic of these groups were to create fear, they would send a suicide bomber to any local strongman that opposed them openly, hujras and houses of local elders were blown up if they openly opposed those terrorists and there was no police to protect them. The locals suffered the most due to them. Pak army gave huge effort and sacrifice to eradicate them, how can u expect locals with families to give such effort? Only an army could have eradicated them and the pak army finally did.
To be be honest, i dont believe any race is superior or inferior. Its only the iman that gives strength. So if pashtuns follow the right path and have strong iman, they will succeed but if they go astray, Allah will annihilate them too, just like others in past. Also the fight u mention will not be about races but about belief, so no way paahtuns will support hindus over muslim brothers.
