Kashmiri voices in the valley need to be recorded as to what they think ,and smuggled out to the world, to raise this issue. this has to be put in the path of all foreign diplomatic entities, so that they have to be on record.
India's undemocratic hypocrisy needs to be called out at every possible public forum.
The key is the Kashmiri Diapsora needs to lead this charge.
If the world see that almost if not all Kashmiris are against this, then they will have to act or be on record as complicit to India's actions
"Edmund Burke once said, for evil to succeed, it is only necessary for good men to do nothing"
Kashmiris need to gather a coalition of Human rights oriented groups from around the world and rally them to their cause

The key is Pakistan should not act militarily, but diplomatically and psychologically at this point. the Case against India's actions needs to be built so their shortsighted actions will be their undoing
India is losing on so many fronts, especially economically (the growth they need to employ their youth has not been delivered by Modi, and with US tariffs and restrictions on Iranian oil imports they have just trying to stabilize themselves) and so they are trying to goad Pakistan into a military conflict to DISTRACT their people and the world.
Pakistan needs to use its diplomatic connections to build up a Sanctions campaign against India. Boycotting India goods, and decreasing Indian imports of Oil (the Pakistan navy can tip off if any illegal Oil shipments are being made from Iran to India).
Also the Indian people need to be shown the hypocrisy of the BJP so that rival parties can challenge this action. If the BJP government can do this unilaterally without the official approval of the Indian parliament, what else can they do in other parts of India.
