With the Games suddenly "controversial," it looks like even fewer foreigners will be making it to Beijing. Heck, I've even had friends who know I'm going ask me "how I could go now." FWIW, I don't think boycotting the Games is a good strategy. It will only unleash an anti-Western nationalistic response from the Chinese people (who probably have no comprehension of why their occupation of Tibet could be wrong!), and sow mutual mistrust. As a smart analyst said, I'd rather see Bush GO to the Games and speak about Tibet while he was there.
Hopefully, the situation quiets down. I scoffed when some folks said getting a visa for the Games could be hard, but maybe I was wrong to scoff.
