The King and the Maoists are pretty much interchangeable. Kick them both out and restore the democratically elected government, which opposes them both.
The parties are allies of the communists, not enemies. Are you even aware of the pact between them? If they Maoists and their useful idiot democrats succeed in overthrowing the monarchy these traitors will be the first to get lined up against the wall by the maoists and shot.
