Kind of a "final straw" scenario? Spontaneous insurrection. It does not look like there is any organized opposition, so it may not be a coup. At least not a successful coup. With the officials of the government having been functionally "decapitated", Nepal may be without any government except the military. i guess we might expect a military regime to restore order. Or India. Or China. This might portend a larger conflict in the offing.

Just thinking out loud.
