One possible scenario: Army will throw in the towel and refuse to fight since the people are not behind their effort. Monarchy will crumble, royal family will flee the country. The parties will be too disorganized to fill the power vaccuum. Maoists will step in declare Nepal a communist state. US, UK, India and other international powers will be herya heryai. meanwhile, there will be minimal real effect on common people's life. So... things go on.
