They also don't have Holocaust history as a part of their curriculum so the idea of the Nazi atrocities is not indoctrinated there.

If you know more about this, how is WWII taught in Japan, for example? Do they talk about their POW camps, like the one in Changi, the Burma Railway? Or about the Sino-Japanese War and the Rape of Nanking?

And I used to read that Germany did try to use propaganda to make locals fight against Allied forces (who generally included countries that either used to keep the respective countries as colonies, or were even then controlling them.) Maybe the winners never cared to counter that propaganda and kept at controlling those countries until they eventually gained independence, so the German influence never had a chance to go away. If nothing is taught much on world history, they never had a chance to change their minds. (I mean, in Europe's schools world history is centered on European stuff, even if other parts of the world are mentioned. It makes sense Asia is Asian-centered and so on.)
