The location of the Tibetan exile government in India, with nuclear weapons, and the deepening linkage between Taiwan and the US-Japan security system counteract reasonable outcomes. Vicious short and long cycles of minor violencies are likely. Autonomy in domestic affairs would be guaranteed. The hurdles to be overcome are considerable.

Tibetans may have to admit that lamaism was brutal, and that China also has positive aspects. This is easy for Taiwan, being itself so Chinese. But Beijing and Taipeh would both have to give up the idea of being the center of the other, finding confederal equality, with Beijing somewhat more equal than the others.
