Tibet is a separate country and actually China has no business to rule Tibet. Maybe several years ago they conquered Tibet and have been ruling it for many years. So also was Hongkong under British rule, but when the time came Britian let go, so now it is China's turn to let go and the whole world should boycot them unless they do it. China has been growing out of proportions for too long and they have been behaving as if they have the right to do anything they want. To be honest they also spell a fair amount of danger to India and do interfere with us in may ways.
The world should back USA, not for any of its selfish motives, but to see that Tibet is made a free nation, and to do this if required, the olympics should be boycotted and also all Chinese goods. It is probably when its economy is hit hard that China may understand.
