The entire saga of Sikkim unrest was the mechanization of RAW under the direction of Indira Gandhi. For that purpose, RAW used migrant Nepali population in Sikkim to instigate trouble. The indigenous Bhutia/Lepcha population was pro-freedom and loyal to monarchy. RAW used migrant Nepalis to organize demonstration against the King, vandalize the properties and to breakdown the law and order in Sikkim to give a pretext to India to intervene. Then Indian army invaded the royal palace, seized the king and organized a sham referendum under the supervision of Indian army whether Sikkim want to merge with India! Even a retard can guess what can be the outcome of that 'referendum' under those circumstances. These are the facts revealed in details in a book none other than the RAW chief who presided over the whole Sikkim operation.
So do not assume, everybody in the world will spoon-fed your official lie. Evidence are too obvious to deny in a straight face.
