Has that solved cultural issues though - rebel leaders having businesses or children studying doesn’t address the right aspect. Basically, the issue here is reforming an archaic culture using existing reformed people from that culture.
No unless Naga are fully embracing Indian society - no longer prone to violence or kidnappings and so on it doesn’t solve the issue. Also, naga rebels aren’t the best analogy - I would almost think of a situation akin to what Sir Syed needed to with the muslim polity all isolated to get them to engage with the British system(ironic since that “get with the occupation”) tone is resonating these days in that area
The problem here is - you’re fighting culture.
It’s almost like saying you want to redo East Pakistan and suppress Bengali culture if aspects(which may not be their fault entirely) of it were actually harming the Bengali people and keeping them suppressed.
It’s a rock and a hard place because trillions and 20 years from the United States did not change this entrenched idea enmasse although it did spur a change which was squandered by corrupt leadership.
Building schools in those tribal areas is a step - but if the elders and more importantly the political leadership is hell bent on saying X while doing Y and allegedly so are members of the deep state - then the common man will resent change regardless.
I am sorry if my points are misunderstood by you. I have no intention to see Pakistan be the hotbed of another insurgency...Beyond popular opinion amongst Indians, I am of a strong opinion that as long as Pakistan and its mainstream politics, culture, and narrative are driven by the eastern part of your nation, It will be a safety valve for India... Your problem with the Western Pashtun population is somewhat similar to our NE Problem...NE people are culturally really different than the rest of India...Even today, we have simply bribed/contained or bought peace with that region( except Assam and Arunachal)... So GOI is spending a huge sum of money to get the people in mainstream...
So you can try to apply the same policy too...At least you have a huge advantage over all these people with the same religion..So i am really surprised to see why Pakistan's stakeholders are not able to bring them to the mainstream in spite of everyone being from more or less the same culture and religion.
