How is it that people still claim this with a straight face? The US has the most number of deaths on an absolute basis, but by per capita Belgium, the UK, France, Spain, and Italy are much worse off. (The US has more people than those countries combined.) Of the large western European countries only Germany did significantly better on deaths on a per-capita basis.
There is a real discussion to be had regarding how Western countries in general did versus the likes of China, Taiwan, and Vietnam, but that's not the same thing.
