May I give my guessing (I own a French "WWII - DVD" titled "Apokalypse").
1. Everything a German soldier is doing is "murder". All French, British, Polish and Russian soldiers were "murdered" by the Wehrmacht (listen carefully to the text). Opponents of Germans, including franc tireurs, partisans and terrorists principally are heroes.
2. Everything a Wehrmacht member touches later comes out to have been genocide
3. In all battles all Germans always are loosing. How they came into territories of Poland and France still is a mystery.
4. German wars are wars of destruction, annihilation, mass murderings, scorched earth and plunder. Others fought one "War to end all WEars" and one "Great war".
5. Only Goebbels used propaganda for lying to the people
