First of all it is worth noting that the Chinese settlers are themselves the product of deliberate campaign of cultural genocide on the part of the Chinese government. While individually they may be innocent, by their participation they have become targets. In this sense there is little difference between them and Israeli settlers in the West Bank or the former French settlers in Algeria.  But even granting that, there is no reason to assume this violence would continue if Tibet became independent and the major cause of conflict, namely the Chinese occupation, was removed as a major issue of contention. It could be expected that a new Tibetan government would have an incentive to avoid all of the harms outlined by the opposition.  Symbolic of this is the Dalai Llama’s remarks that Tibet’s future is linked to China’s and that an independent Tibet would benefit from a close relationship with China.
