As for the USA relaxing covid-19 restrictions, well, why not? See how they go. It's kind of like watching what happens in a petri-dish from a long way away. \Same with their gun laws...or lack of laws. If guns and disease make them happy, well, good. They don't need to ask anyone else's opinion, and they never do anyway. If it all means less Americans, the real world can cope with quite a few million less of them in a minute.
