The praising of swedish policies seems to largely come from folks in the US wear we have no social/cultural consensuses because the country is so divided
Asia did better because people accept mask wearing--true but it's still pretty minimal in normal times. But somehow lack of mask wearing probably didn't matter in Sweden--but that's because they hate getting anywhere near another person anyway. But in the US Trump supporters not wearing masks is a big problem. Etc.
I'm not going to argue that nothing matters. (Certainly protecting especially vulnerable populations is something a lot of places totally whiffed on early.) But I expect that some things people are really polarized about don't matter much.
I don't claim that Belarus, China, or even Japan have perfect data. But they are not North Korea, and if they had widespread devastation their neighbors would be able to tell. I don't think Belarus' data is particularly less trustworthy than Russia's. Both were willing to report cases going steeply up, when it was true.
The other is that, for example, Denmark opened up their elementary schools again in late April, and Finland in early May. So even the comparison to other Scandinavian countries is missing a lot of nuance. Plus, I am led to believe that Sweden DID close their high schools and colleges, since it was easier for older kids to do distance learning.
The nasty secret that neither most news articles, nor this one, admits to is that, if you take all available evidence, national policy doesn't seem to have mattered much one way or the other. Sweden is in the middle of the pack among western Europe. Belarus is in the middle of the pack among Eastern Europe. Japan is in the middle of the pack (or better) in east Asia. If national policy were important, they all should be either the best or the worst.
I think maybe we just did stuff, pretending it would matter, while the virus went about its normal pandemic business, and nothing we did really mattered that much.
