They're traitors who think siding with terrorists is their path to political power.
Just a couple of years ago, the Nepalese Gov't was backed by India, China, Pakistan, and the United States -- literally by every major regional power. Today it is backed... by nobody. Why not? Because the king is a nutcase. Restore the elected government. Either you trust democracy (the people elected a large anti-Communist majority) or you don't.
The fact that India, Pakistan, China and the United States agree on anything is amazing. And yet they are unanimous: the Maoists and the King are both equally terrible and the only legitimate government is the elected one.
