thats false read history, 80K local AJK militias liberated their own land, so did Gilgit people (only people who propagate that pov are indians who say these lands were conquered by outsiders not liberated by the local people thus P-OK)
So much has been written about it, please read up - yes tribals did come afterwards to push further into IOJK alongside already established AJK militias, and pak army irregulars but were unsuccessful because Kashmiris from the valley werent so keen on the idea after seeing the bloodshed it caused in the neighbouring regions
no due to diaspora money their HDI lvls, literacy rates are higher than ours
Till date all Kashmiri resistance group relied heavily on local Kashmiris, madrasa students of Panjab- 90 to 95% (same deobandi madrasas with same political affiliations JUI & its off-shoots, Hell the same groups even started the Punjabi Taliban of 2000s but after attacks on civilians their support dwindled and the group eventually disappeared)
so much for dont care
get your stereotype right, AJK people are like Potoharis not Kashmiris - there are 10x more butts in Lahore, Sialkot than AJK
Instead of foul-mouthed emotional rants, maybe just maybe look up stuff beforehand
