India and China both face a significantly more difficult geopolitical reality than the USA.
Some of the world's most westernized and developed countries (Spain, Israel) are starting to use violence and suppressive tactics now that they are faced with even the smallest amount of secessionist unrest.
Kashmir is one of the most militarized border zones alongside the West Bank. I fully agree that there might be better and less suppressive methods that the Govt. can use to deal with the Kashmir issue, but to act as though a USA like policy would work in countries with very different ground realities is being willfully arrogant.
At the risk of sounding too cold, if the choice was between death of a few million people (which India has a long history of) and complete destruction of communication frameworks. I would choose that latter.
Now the big problem with what the Indian Govt. is doing, is that this has been going on for almost a year and they are making no efforts to bring Kashmir back to "normalcy". Such draconian policies should only come into place for very short durations with measures for removal, the second unrest goes below a certain point.
