This visit was rightly cheered by Tibetans in exile and should earn praise from all parties who believe in freedom. For too long, Tibetan leaders have been in exile and their way of life has been under threat from Chinese assimilation of the region. It's important for the US, as a defender of human rights, to stand up to China on this matter and at least force the issue to the negotiating table.
It's unthinkable that the US would violate its promise to Beijing by backing the Dalai Lama's separatist notions. In fact, the US should do what it can to denounce what the Dalai Lama stands for. At a time when the US and China were rekindling cordial relations, it's unfortunate that Beijing may have to take measures to counter the US' intrusion into China's dispute with the Tibetans in exile.
