If you selectively cherry pick a list of nations to compare, as many on here seem to do -- you could of course make US look better than the rest of the world in case-fatality ratios. I can also, similarly, make it look the worst, as shown in the table below.
If you choose a more objective and representative sample of countries around the world, you'd find that US is not the best, it's somewhere in the middle of reported case fatality ratios. On the other hand it has the greatest wealth and resources to combat the virus and
should likewise, have the best case fatality ratio. As can be seen here, it does not.
The two statistics US indisputably leads the world in are absolute cases and deaths. Not a flattering accomplishment, for the wealthiest country on the planet.
