Expanding upon her award-winning investigative series God’s Warriors, CNN chief international correspondent Christiane Amanpour reports in a new documentary that examines the nexus of politics and faith. For Buddha’s Warriors, Amanpour explores a new generation of Buddhists who are actively engaged in political struggle. These believers of love, kindness and nonviolence struggle to remain true to their beliefs while at the same time confronting severe political and cultural oppression. In Buddha’s Warriors, Amanpour investigates the roots of the conflict between Chinese authority and ethnic Tibetans. Nearly 50 years ago, the Dalai Lama fled Tibet after a failed uprising against communist rule. Tibetans say that all but 13 of 6,000 Buddhist monasteries were destroyed under Chairman Mao’s Cultural Revolution from 1966 to 1976. Those that have been rebuilt are now under the close, watchful eye of the Chinese government. Monks there say that they are forced to denounce the Dalai Lama and swear allegiance to China.
