India is threatening to blockade Nepal, to force the king to reinstate elected officials in the government. India has used blockades before to force Nepal to do what India wants. There was a blockade in 1989, to force Nepal to not buy weapons from China. In 1974, there was a blockade to force Nepal to stop protesting Indias annexation of nearby Sikkim. But in this case, India does not want to aid the Maoists. It is pretty clear that the Maoists want to establish a radical dictatorship in Nepal, which would be less democratic than the king, and a lot more prone to violence against the Nepalese people. India also has its own Maoist rebels, and knows how violent they can be. But the actions of the Nepalese king are very unpopular in India, and everyone knows that India has the final say, by cutting off the flow of vital supplies to Nepal.
