The uprising received extensive assistance from the U.S. Central Intelligence Agency (CIA), including military training, support camps in Nepal, and several airlifts.[114] Meanwhile, in the United States, the American Society for a Free Asia, a CIA-financed front, energetically publicized the cause of Tibetan resistance, with the Dalai Lama's eldest brother, Thubten Norbu, playing an active role in that organization. The Dalai Lama's second-eldest brother, Gyalo Thondup, established an intelligence operation with the CIA as early as 1951. He later upgraded it into a CIA-trained guerrilla unit whose recruits parachuted back into Tibet.[115]
