That's not the point. My only point is their r0 has been above 1 since early November. They went from 100 news cases per day to 1000 in a month and a half. That isn't "succeed[ing] at containing this virus."

I would assume this is a new generation (new wild-type) which has been reintroduced from the West. As such, Korea did succeed at containing the virus: their only problem is that Western countries didn't bother and made the problem magnitudes more difficult for everyone.
Im pretty sure the standard is not having the virus under control 100% of the time. If you do, it’s almost certainly because you have erred way too far on the cautious side.
The standard is keeping the virus well under control for the majority of the time, ans when you do have a flare up, bringing it back under control before it becomes too bad.
