Trump may be a **** but he's getting the math right.
No, this is far too simplistic for a comparison and shows nothing - the USA is a huge country and many states have barely had any cases yet. The other countries in the comparison are much smaller and have a much more dense population.
We could look at a more comparable area and population that shows the opposite - e.g. New York state has 854 deaths per 1m pop.
(Using a population of 19.44 million and number of deaths 16599 as of 25th April, from Wikipedia)
