Please point out any alternatives.
Kashmir's status has little to do with the Pakistan's Kashmir narrative. Pakistan was trying to internationalize the conflict before the article 370 revocation and has increased efforts after the revocation of the article. For Pakistan there is no big policy change. This is because the ground reality is that India is in control of ~45% of Kashmir and will keep it as a matter of national pride even if it has to oppress the local Kashmiris and the only way it can be taken is through military power.
What Pakistan can do? It is better to wait for the Kashmiris to rise against the oppression. Then maybe Pakistan can also help them. Up till now, it does not look like there is any Kashmiri resistance. They have decided to roll with the flow for now. Cant help them in this condition can we?
The Uighur muslims are also suppressed to a level that they cannot challenge the Chinese state. I predict the same outcome for the Kashmiris. A minority cannot challenge the powerful institution of the state. The State is just too powerful. Unless of course you are a Pathan. Can't compare them right?
