When we look at the overall death rate during the pandemic (i.e., completely disregarding covid tests), it's still true that the US had a much higher increase in deaths than most of the world.

Even if you limit this to places where reporting is fairly accurate (the first world, or even just rich European countries), it's still true.

The "because we tested more" line is complete nonsense, we can literally count the people missing and end up with a very similar result.
