Freedom fighting by definition is done in one's own land. Pakistani punjabi lashkars "freedom fighting" in Indian Kashmir is an absurdity. And most fighters in Indian Kashmir today come from across the border.
There is quite a difference between random acts of violence and proper armed struggle that builds a new nation. Yes, Kashmiris taking oath in a nation of Kashmir would indeed surprise me - because I know that that's not going to happen. Occasional fidayeen acts cannot give birth to new nations.
The Mukti Bahini was an organized fighting force raised and trained by RAW, but belonging to their own land, and they honourably fought their oppressors and created a new nation for their people. If and when Kashmiris do smoething like that, wake me up.
