China, NZ, Japan, SK, HK, Vietnam, Thailand, Iceland have all done a good job of limiting the spread. Mainly through high mask compliance.
China? Nobody really knows, as the government lies.
NZ? Too small to compare to USA.
Japan? A culture of willful compliance with authority exists there. Ask any American who has ever played baseball in Japan.
SK? HK? Vietnam? All too small and too authoritarian countries or with traditionally compliant with authority populations, and none can compare to the USA.
Thailand, Iceland? Seriously? You think they compare to our country in terms of size, mobility, and an independent attitude? HOW?
The simple fact is the USofA had one of the worst responses.
Well, no, you can't say that is a "simple fact", until you can show a country that was similar in size, demographics, and with a similar culture to ours. You want to say the US could have done a better job, that's one thing, but don't do it by comparisons such as these.
They simply don't work.
Maybe you should spend more time here in this country. You might know more about what is really happening in it.
