try doing what these protesters do in US of A and see the repercussions.
Is USA oppressing mexico (for instance) or a nearby land whose people want independence? NO!
Secondly, the law enforcement in USA follows rules and regulations, people are not outright shot for voicing their discontent. There have been hundreds of marches over the issue of immigrant, and nothing of the scale of India was done.
How can India continue on sing the Greatest Democracy tune if it oppresses a land and people who are not an integral part of India, never have been, never will be. It is internationally known as Disupted Territory a.k.a Occupied Kashmir because of that very reason. It IS occupied by India.
I would sincerely want to see India shine bright and be the Greatest democracy and its' economic growth so strong that it can draw incentives for the entire of Asia, but i feel the Kashmir issue is just hampering India's efforts. Without having to worry about Kashmir, India can truly reach the sky in terms of economic growth and internal development.
The longer this is dragged on, the more tainted India's label of Democracy will get. It's the cost of being called the Biggest Democracy of world, and India must pay it, sooner or later.
Violence from either side does not and will NOT achieve anything. Intense dialogue is needed where the situation is dealt with as a final stage. Period.
