You are probably right, to a degree. Maoist victory in Nepal would obviously have negative consequences across the region, and India will be one of the most important areas of transition in the upcoming century. I suspect that the relationship between India and Nepal is rather one-sided, however... I imagine the worst case scenario would make Nepal the Cuba to India's USA.
True, but I suspect that India is more vunerable than the US. It has more serious problems with the caste system, for example.
