Don’t forget the one that has really gone down the memory hole: Finland.
Everybody talks about the gallant Finns of the Winter War, and nobody ever mentions them fighting alongside the Nazis later in the war.
BTW, the Finns were the only allies whose divisions were regarded by the Germans as equivalent to a German unit.
I noticed that Finland was not on the list. Many of Hitler’s forces struck the USSR from Finland and Great Britain declared war on Finland at that time.
Sweden was neutral yet they allowed German troops to use their railway to get to Norway.
If you think about the circumstances in Europe at the time, allying with the Germans may not have been such a bad idea if you were a Eastern European nation. You were pretty much stuck between choosing the USSR or Nazi Germany conquering you at some point, or allying with one of them. Hell, at one point in British Palestine, members of the Lehi floated the idea of allying with Germany to drive the British out.
