Darjeeling was never a part of Nepal. British got it leased from Sikkim. Sikkims was never a part of Nepal either. People of Sikkim was Lepcha, and Bhutia Buddhists, not at all Gurkha Nepalis. However, because of this bloody treaty Nehru signed Nepalis took over Sikkim and about to take over North Bengal as well. Nepalese are foreign citizens. India must declare it so and try to get rid of them from Sikkim, Darjeeling and other parts of India. Otherwise they will turn India into another Nepal and KathMundu( means Heads Cut Off). they are violent people. They should be shown the door to Nepal.
