Libertarians on Kashmir

I would very much like to hear the opinion of Indian libertarians on Kashmir. Why libertarians in particular...because respect for ‘freedom’ is such a central component of libertarian philosophy.
This is how I see the Kashmir issue...Kashmir was a kingdom on the northern fringe of present day India and geographically contiguous to present day Pakistan. Even though the ruler was a Hindu Dogra, the population was predominantly Musim. The princely states, at the time of partition were given a choice of aligning with either India or Pakistan or remaining independent. The King of Kashmir, Raja Hari Singh wanted to remain independent but after tribals from North Waziristan attacked Kashmir in a bid to forciby align it with Pakistan, Raja Hari Singh turned to India for help. India offered help on the condition that Raja Hari Singh sign the instrument of accession, which would make Kashmir a part of India. Raja Hari Singh agreed and signed the agreement. In 1948, India took the matter of Pakistani aggression to the UN Security Council. The resultant UN resolution demanded an immediate ceasefire and withdrawal of all Pakistani presence and retention of a minimal Indian military presence. Furthermore, the UN resolution stipulated that the final disposition of Kashmir should be done based on the will of the people of J&K, to wit, a plebiscite was promised to the people of Kashmir and is part of the UN resolution of 1948. However, we have denied the Kashmiris this fundamental choice so far. Doesn’t this conflict libertarian polity?
My own thoughts are that a final resolution of the Kashmir issue can only be achieved through a plebiscite administered by a neutral UN team or even by one of the politically neutral Nordic countries. I do not want us to forcibly hang on to any area that does not want to be a part of India...and certainly not one that has been bleeding the coffers of our country for the past 60 years. Let there be a plebiscite and let us be brave enough to accept the result if the chips fall where we would not like them to. My only caveat is that the Kashmiri Pandits who were in Kashmir during the time of the first UN resolution, or their descendants should also be able to participate in this plebiscite. This is fair as they left Kashmir only due to the ethnic cleansing against them. Also, I personally think that this will greatly improve India’s chances of ending up on the right side at the conclusion of the plebiscite.
