In any European country, afaik, Bernie and AOC would match a left-center, moderate progressive party.
It's funny that some of those countries actual left or far-left parties are kind of "let's burn the capital and go back to them fields attitude".
Those parties are rarely a significant part of the governing process, and shouldn't really be considered as a fair barometer of any given country's overton.
Also, several European socialist, democratic socialist, and social democratic parties have labelled Bernie's proposal for M4A as radical even by their standards, and American social politics to be well to their left, particularly on race issues.
France had a national panic about "American University Wokeism", which can basically be defined as "not being rancid festering dick cheese to muslims for the jollies and trying to use gender inclusive language to recognize trans and NB folks."
