the thing with many usa states is wigwam they are huge, populations are spread out which lessons the impact of rule breaking and reduces the need for lockdowns. california relaxed its rules and look what happened their rate has rocketed.
as has been said we will only know the result at the end and all the bickering by politicians and the hot air from the consiracy theorists etc just muddy the waters.
i dont think there is one solution for all, countries are so different some with vast land tracts and small population centres and others with huge population centres and suburbs that end up like petri dishes.
lets hope the vaccines get out there quickly and they work.
it may be the one thing we got right.
