I wonder the same. Maybe there was no chance of it to begin with. Unless we became adamant and vocal about it, something could have come about still. Maybe semi-autonomy for some malwa districts perhaps, anything to keep an armed force alive. But knowing our leaders, they would have merged it within a decade or two under some nehru-treaty!
What I do find interesting is how there's a tentative "shaming" of India under Modi, in terms of the Muslim issue in India. If India continues on its current course, I expect that dissent from the West to grow louder in a way that nobody does with sincere gusto with places like Saudi Arabia and China, i.e. countries the West can't afford to pee off despite their questionable records on how they treat certain sections of their respective societies.
