Small sample, since I come from a country of only 2M people, but there's a growing number of people, including historians and history teachers, that are trying to rewrite WW2 history by framing the Nazi-collaborating groups as the good guys, fighting for our country to rid us of the communist evil that was the liberation front - and everyone is just eating it up. The ordinary people risking their lives to fight literal Nazis are now depicted as the "aggressors" and the people that marched on our own cities under Hitler's flag are the good guys?? Why, because the mere idea of communists doing something good is so dangerous to neoliberalist society that we'd rather call literal Nazis the good guys??? But if you say "communism bad, they fought communists => they were the good guys" and conveniently fail to mention the whole Nazi-collaborating thing, no student will question it because they really don't care anyways.
// Sorry, this turned into a bit of a rant, but yes, there's definitely a lack of understanding of history in schools these days and certainly some pretty powerful propaganda
