Amid the ongoing LAC standoff in eastern Ladakh, China needs to be shown a red card. And Tibet can be one, though one has to build it into a potent red card along with others. It will be a long haul for India. It should be a slow bleed for China.
The future course of the Sino-Tibet-India relations will largely be dictated by what the people of Tibet want and which way they swing. Also, any chance of change is only feasible if there is full support from India, US and Europe. So far all three have left the Tibetans in a helpless and tangled condition.
