NC,
I agree with what you said, except maybe for the Swedish example, their population density being very different than other countries around the world (especially HK).
Furthermore, their self-discipline compared to other Southern Euro countries could well have played a big role in their good results.
Seeing how bad it was in Italy when it all started, it was logic to impose a lockdown or at least restrict travels.
But now that hospitals around the world are basically empty?
It seems nobody taking decisions knows what the R stands for in the CLEAR model...
