> closing their borders to fleeing Jews.
This is such a landmine topic, because most countries did this, including the UK and the US; see e.g. the MS St. Louis. This is why there are several "heroes of the resistance" that in modern parlance are "people smugglers", forging credentials and visas in order to help people escape.
Today you see exactly the same hostile attitudes to non-white refugees of basically every war except Ukraine.
Despite what Hollywood says, WW2 was more to do with German militarism and expansionism than the Jewish question. The Allies were certainly willing to use pro-Jewish sentiments and some Jewish troops, but it was never presented as the main issue.
It's also why Germany did the death camps. Originally their plan was just to force them to leave but most countries were not allowing them to do so.

Perhaps that's because most of those refugees could more easily shelter in neighboring countries that they are more culturally similar to... if shelter was actually the primary thing that they were seeking.
Niels Bohr, the Great Dane, was one of these skid greasers! He worked with the queen of Sweden, and also used his academic contacts in various countries to secure jobs/visas.
