Well, self immolation may empower and awaken Tibetans. But something effective must be done to get the Chinese out of Tibet. It may be far too late.
Tghat can only be accomplished by force majeur.The ancient darma Kings of Tibet, such as Gesar of Ling, had no problem in that regard, it is how Tibet was created by the major clans. There must be an enlightened military, or all is lost.
http://www.guardian.co.uk/science/2010/jul/02/mutation-gene-tibetans-altitude A gene identified as EPAS1 makes all the difference. 9% of Han Chinese have it ~ 87% of Tibetans have it ~ it is believed this is the gene that makes it possible for Tibetans to live at high altitudes far longer than people who are not Tibetan ~ so, eventually, the Chinese Chinese die.
