Yeah well, China started building the military road in Arunachal Pradesh in 2000. What have we done to stop them? Nothing, because we are afraid of the Chinese retaliation, and can't handle simultaneous war with TSP and China. Now China is building a military road through Bhutan, and the latest news is that our mahaan politicians will complain to Chicom about it in January sometime (check link above).This is India's neighbourhood. We, not the US, need to protect it.
Politicians, who don't even have enough balls to fight the Chinese when they are building military infrastructure on Indian territory, will surely do a lot about the Chinese road-building in Bhutan.
If we can't do anything about it, the best alternative is to get somebody who can. If we get American involvement, then that keeps TSP from attacking us while we take care of the Chinese infiltrations; IMHO that solves half the problem.
Getting Americans involved may also scare Chicom away; Chicom keeps throwing verbal threats of invasion at Taiwan, but why haven't they attacked it so far? Because they genuinely fear the US. Give the Americans military bases in India to operate out of, and I guarantee that they will forget TSP. India will become a major ally in the war on terror. Give the US a reason to protect India, since we certainly haven't been able to keep the Chinese off of our territory.
