The talk of an olympic boycott by the US president in the opening ceremony in China is ridiculous.  It would surely have zero effect on Chinese policy toward Tibet.  It is naive beyond description to think that those sitting in power will reverse policy in such matters. To reverse a policy regarding sovereignty that has been defended with violence is to admit a shocking error in judgement and to accept responsibility for a wrong that is possibly criminal.  Autocratic governments never do this. Ever.

China has supported considerable US debt and continues to do so. We’re going to publically humiliate our bankers? We’re going to poke a finger in the eyes of those who have been supporting America’s deficit spending and military adventurism in the sandy spots of the world? I don’t think so. 

Buying fewer goods made in China is one good response. Put the money in the bank. Feed the pig.
