There was another topic in the 50th section where someone asked why Rommel was on the box and not Hitler. This person pointed out that you saw faces like Churchill and Stalin (world leaders) not Montgomery or Eisenhower (country specific generals) for example.
The answer was that the game would not be legal to market in Germany with Hitler’s face. I would imagine this would fall under the same school of thought. Germany doesn’t deny that the war happened but they would like marginalize the bad PR that goes with it.
