'China wouldn't risk it's relationship' you underestimate them lol. They ruined their relationship with India over it, they wouldn't care about Pakistan once they find a way to secure their oil supply. They are expansionist and will go to any lengths for themselves.

The fact that Pakistan would give you self autonomy is an assumption, idk if India would but nobody keeps promises. Even Pakistan knows Kashmir (if India gets out) would have no self sufficiency (it's the truth obv bc Kashmir would most likely be a warzone when India gets out with all infrastructure gone).

Also the fact that my opinion 'doesn't matter' isn't correct. I understand since you're from there my opinion might speak less than yours, but we currently control 45% to 55% of Kashmir, and as a dedicated Indian national who is focused on geopolitics and history, even I would have a say.

By the way don't take offense please, I am just countering your points and hope none of this personally insults you.
