The nations along the Sino-Indian border are used by both countries either as pawns or neutral zones. The Nepal situation seems close to the Sikkim situation. Depending on whose version, Sikkim ruler faced social breakdown and internal civil war. Some believed the situation was instigated by India to force the ruler to accept Indian rule or face street justice from the rebels (allegedly supported by India). Others say it was a natural internal strife and India took advantage of it to enter and later annex Sikkim. Nepal Maoist were supported by Indian Communists while the Indian government stood idly by and did nothing??!!! How do we know if the Maoist movement was used by India to destabilize Nepal, so it will serve as a strategic pretext or strategic pressure to force the king to allow the entry of Indian forces so the rebels (who served their purposes) will be destroyed and Nepal is firmly under Indian control? I think this is Act One is a long fubuki dance between China, and India. I think India will occupy Nepal, destroy the rebels and refuse to leave. China will capitalize on the Nepalese resentment of Indian occupation and Act Two of the play will begin. In the meantime, if Nepal falls to Indian control, that leaves only Bhutan as the remaining independent nation along the Sino-Indian border. The only good news for the US is this situation will destroy the attempts of China and India to cooperate economically. They have been trying to open their borders for trade in the last six months. We want India as an ally, not a third party who can play the China card against us or the US card against China, thus reaping rewards from both sides.
"Bhutan as the remaining independent nation along the Sino-Indian border."
Bhutan is under indian control They use indian currency and india in in charge of the military and foreign affairs. It is all but an indian state.
