According to the Worldometer, as of 8/4/2020 the United States has the 10th highest per capita COVID-19 case rate among over 200 nations surveyed. No major nation has a worse rate.
The U.S. also has the 10th highest per capita COVID-19 death rate. However, some major nations do worse: The U.K., Spain and Italy.
The U.S. track record is not clearly the absolute worst, but it is clearly $h!t and worst than most.
Just a general point, I don't think the figures at the moment for any nation match reality, I imagine there are at least 10x the number of cases. There has been a cover up in Iran of deaths (add 30K to the total) Furthermore, expect the UK figure to drop once the government has taken out suspected and non-contributing deaths, which they are currently reviewing.
