I don't think Nepal can ever be a country ruled totalitarian communist party. Seriously, If people can rise againt autocratic king do you think they will just keep quiet if the communist party takes over the government? We have many political  parties and their followers. It's not like cuba or N korea where all parties are banned. For instance, If Maoist were able to take over all aspects of the government an ban all parties do you think everyone will shut up? I can't image India or even China will support a totalitarian government in Nepal. Remember that These two neighbors, esp India have always sided with the people regardless of what your opinion is.
