The Dalai Lama marked his fiftieth year in exile earlier today by demanding “meaningful autonomy” for his Tibetan homeland, where Chinese authorities have tightened security to stifle protests against their rule. The Dalai Lama slammed China for bringing “untold suffering and destruction” to Tibet and turning the region at times into a “hell on earth.” His words came on the fiftieth anniversary of a failed uprising against Chinese troops, which led to his exile.
