I think India should come out with an unambiguous stance of opposing any excessive force and also starting dialogue with Tibet representatives. The reasons are clear
1. If India wants to be a superpower, start behaving like one, and be firm on a stance
2. Tibet is strategically located to North Indian border. Having a peaceful region is in India's interest
3. China is always taking us for granted, infact opposes our growth. We have no reason to be shy of what we believe in i.e., ethnic harmony.
