It’s important work. Funnily enough, I frequently refer to this IRL in conversations about education and propaganda. Like you, I know the Nazis weren’t alone, so I ask, ‘why weren’t you taught anything about the Spain, Italy, and Japan in school?’ That question is often enough to get people to think about the extent to which the West really did (it didn’t) eradicate fascism after WWII (which serves my rhetorical purpose). But I don’t have much more to add than that because, I also wasn’t taught about what the fascists of other countries were up to in the twentieth century. So it’s great to see someone digging up sources.
