The most likely source of possible foreign intervention in Nepal is from India (if they ever dared to), but they should also keep in mind that there are 12 Gorkha Regiments as a part of Indian Army. Nepalese should think about giving birth to another Baburam or Prachanda within those 12 Gorkha Regiments of Indian Army and initiate a mutiny in Indian Army. By the way 1/10th of Indian Army is staffed by soldiers of Nepalese origin. Another option is to start another massive and extensive "Maoist-like" insurgency in the all bordering states of India from east to west of Nepal. Molest Indian security forces with Maoist like hit-n-run tactics all along the frontier. Make the entire nation totally hostile and ungovernable for Indians so that they back off just like the Soviet Troops left Afganistan after bitter defeat in the 1980s
