I know. It's just perpetuating the dumb idea that the Olympics might not happen. There were people less than a week before Tokyo thinking they might pull the plug. But they didn't, and they pulled it off. To that end...
I would absolutely use the word success to describe what Tokyo did this summer. They were forced into an absolutely unprecedented situation and managed to complete every event, award every medal, and somehow put talks of COVID largely on the backburner throughout the games. Sure, it would have been better if they could have postponed it another year, but that was never going to be an option. Given the circumstances they were up against, they couldn't have been expected to do much better.
As for Omicron.. maybe it's because I'm in the United States and I'm seeing different reports than you are, but where'd you get the 0-20% numbers? Of course there's reason for concern, especially so far as international travel is concerned. But that was the case with Delta over the summer. It sounds like this is going to be worse, but we're further ahead on the timeline of vaccinations than we were 6 months ago.
Chances are, Beijing will be a lot like Tokyo.. some athletes will test positive and not be able to compete. Some may decline the opportunity to compete in the first place. But I think when we're looking back at this in March or April, it'll be the same sentiment. That it was foolish to go ahead with the Olympics, but they did it anyway as best they could. Because we know darn well that the IOC and the Chinese organizers won't spend more than 5 seconds considering a postponement and creating another year of anti-China backlash. At this point, I'm sure there's sentiment from almost everyone to just get this over with and move on to Paris and Milan-Cortina
