As a support for Tibetians, what happens if all the nations doesnt participate in Olympics. Now-a-days Olympics is much of a money generating event than an event which develops brotherhood among nations.
China is becoming more and more ruder with its increase in power and being recognized as one of the Super Powers in the world, nobody is questioning it.
Let nobody participate in Beijing Olympics and create a major dent in their investment and earning opportunities. It will serve as a good blow from the world opposing its rude manners.
