China is managing the situation horribly; probably the worst PR disaster since Britain vs. Gandhi. So first of all, who's the face of Tibet? The Dalai Lama. Who's he? The leader of the world religion best kmeown for its constant peace and compassion, and he's the best example of it. He's a remeowned peacemaker, and just generally the nicest, most likeable guy; it's really that simple, there are no more complex words for it. He continues to advocate peaceful protest and outright friendship with the Chinese. Secondly, there's Tibet itself. China invaded it a fairly long time ago, and as far as I kmeow, they had literally no reason. They can't justify it in any way, and they can hardly justify forcing the Dalai Lama into exile or having military crackdowns. Furthermore, they're a Communist power in a world where nearly every other world power hates, or at least doesn't follow, Communism. Also, Tibet is one of the most impoverished, even pathetic (in the genuinely feeling bad for the people sense) regions of the world, and this is a world where governments are blamed for that, so the blame falls on China. Then, when the people protest peacefully, most of them being Buddhists and many being monks, China institutes military crackdowns; people trying to cross the border to visit exiled family members are frequently shot. And what's the icing on the cake? You're hosting the Olympics, so all eyes will be on you while you're supposed to be setting an example of a civilized country.
So here's the summary: you have no good reason, economic, ethnic, or otherwise, to occupy this country. They don't want you. They're saying so publicly. Their figurehead is one of the most liked/loved and respected people in the whole world. You're making yourself look bad. What're you doing?
