The problem with this thinking is that, statistics show that people who didn't lock down or wear masks, were far freer from cases and sickness and death than those who did.
problem with your thinking is.
countries that closed the borders efficiently. and the tracked and traced people at the borders.. kept it out of their borders to allow people within to be more freer
so if you want to blame anyone for masks and infections and deaths.
blame trump for keeping the flights open and purposefully doing repatriation flights from hotzones. and then not monitoring/quarantining them people once in america
you should try to use common sense and facts
