Lobsang Sangay, Leader of the Tibetan exile movement

The Dalai Lama, the spiritual leader of the Tibetan people, has withdrawn from active politics. Lobsang Sangay was recently elected to head the Tibetan exile movement and must now lead his people's struggle for greater autonomy from Beijing. He has an impressive record as a scholar in the United States, but he's never actually set foot inside Tibet. Will Tibetan unity fracture as leadership passes to a new generation?
