The whole "Boycott the Olympics" campaign is a sham. I bet many of the people proposing such are doing so on Chinese made computers whilst wearing Chinese manufactured clothing etc. China is central to globalised Capitalism. The reason why the Western economies have enjoyed historically low inflation over the past 15 years or so is because workers in places like Shenzen work for wages which are, to Western eyes, very low. Do you really think the Murdochs, Bush's and Brown's of this world are gonna risk all that to help out a backward, marginalised Asian minority who were shitting in the streets 30 years ago? No, me neither.
It's important not to get too misty eyed about the pre-1950 Tibetan regime. It wasn't this 'Hippy' Shangri-La where everybody sat around and laced Daisys through each other's hair that the 'Free Tibet' Campaign would want you to believe. It was content to leave the mass of it's population in abject poverty, it tolerated Slavery, Feudalism and permitted the practice of cannibalism for certain Buddhist cults. Buddhism has always enjoyed a remarkably good press in the West but certain strands of it are as nasty, violent and bigotted as any other religion.
I've been to China (including on one occasion, Tibet) many times and the Chinese Communist Party ain't going anywhere. Sure, the Chinese may complain about corruption but they are not going to risk the real gains they've made by opening the Pandora's box and removing the CCP. In fact, the rioting of a marginal minority may have the effect of binding the Han (90% of the Chinese population) to the government.
A lot of the orchestrated Hue and Cry over Tibet we are going to suffer over the next 6 months is going to take the form, I fear, of barely disguised Sino-Phobia. "Yellow Peril" nonsense which will actually have the effect of strengthening the grip of the CCP in the short to medium term.
