This has only a little bit to do with Russia, but is way to interesting not to post. I don't think we ever saw this one when watching cartoons on Saturday morning.
It's a Merry Melody title "Russian Rhapsody" about Hitler (yes, Hitler) getting on a plane to bomb Moscow. Fortunately for Moscow, gremlins cause all sorts of problems, including one that's a Russian caricature. A really great example of WWII propaganda, and there are quite a few moments that make you thing "Oh shit, did they really do that!?"
