I find it odd that people are comparing "worst" by number of cases and not accounting population. The US has 320mn people while Italy has 60.5, Spain has 46.8, and Germany has 83.8. These are the countries with the most cases and by population the US is doing the best out of all of them and Spain the worst. If we look at deaths, Germany is only slightly better than the US but Spain and Italy are each much higher.
The US sure has a lot of problems, but that doesn't mean everything we do is the worst.
