Roger E. McCarthy created the CIA Tibetan Task Force and personally trained the first six Tibetans. Although others have tried to take credit (decades later) for much of his work, McCarthy was and still is The Man. He also debriefed Gompo Tashi following his escape to Darjeeling--the only non-Tibetan to have done so. For resolutely correct information about the CIA involvement, this is the primary source. Given much of the crap one finds in the bookstores on Tibet, it is a great pity this work is not more widely read and recognized--particualrly in understanding the horrible yoke of the Chinese:

"In most countries, all the jargon attendant to Communism means very little except to those whose duties require them to be communist parrots, but to Tibetans, freedom and independence and their religion are precious and not to be tampered with. Now all the tribals finally concluded after some six years of barbaric treatment by the Chinese that no more time was to be wasted waiting for things to get better and that with or without the blessing of the Dalai Lama the Chinese were to feel the sword. To the majority of Tibetans, it was basically a choice of either trying to escape to another country or fighting to defend their own."
