The EU and the USA are very comparable in almost always.
The EU is comprised of member States, some very large, populace and very dense with high tourism rates (more density that comparable US big cities with more tourism) and some less dense and spread out and less wealthy.
The USA is comprised of member States that meet that same complexion.
Total population of EU ~445 MM.
Total population of USA ~330 MM.
The EU had covid hit EARLIER with devastating effect and thus if it just a given that once opening things will get as bad as they are in the US then it follows the EU is now worse or went through a worse rebound of Covid.
The facts show otherwise.
