edit: and I agree a lot was done, but certainly not in any unified manner. in this age of hyper-globalized economies, countries cannot effectively act as individual entities when dealing with pandemics.
We have seen similar or even worse numbers in UK/EU over time. Theres a notion of being open, and then there’s public conformance.
Totally agree masking and filtration could have been massively improved, but it wasn’t known for a while that masks were the right thing. Everyone needs to give the health officials some latitude when something is brand new and being studied in real time. Of course communication could be improved, but it didn’t help it was also politically inconvenient (along with all the false information) so the comms no matter what would be challenged.
