The Kashmiri people will have to find unique ways to keep world attention on this siege. In a show active non-violent resistance through non-cooperation they will keep on winning over international supporters.
Visual and universal signals of distress that are unique could allow photos to get out. Videos and Photos have gotten out to the world, and a steady stream of these videos showing Kashmiris rejecting the Indian state can be very powerful. It will help them maintain the moral high ground. Methods, like wearing an arm band or shirt with a slogan of protest, or just massive numbers of people sitting down in the middle of the street, and singing protest songs broadcast to the world are very inspiring. Another method would be refusing to pay any and all taxes, and shopkeepers refusing to accept any taxes on behalf of the Indian government.
Protests methods used by Gandhi can also be very symbolically powerful. Re-enacting literally some of the Gandhi like protests can really get the message across to the Indian population and the World.
