I get the feeling that the translation software being used by the Original Poster is somehow misinterpreting when it states the word "protagonist".
But what I get from your posts, Rising Sun, is that you feel that Germany does not have enough events or other items that grant it the same level of "character" that other nations have. In example, the text of the event "Tora! Tora! Tora!" for Japan, or others that give you at least some vague sense of what those countries' people were feeling and why they went to war.
Germany doesn't have much of these things in the game because of the nature of the Nazi beliefs, their reason to go to war, and the things they did to those they conquered. Its a very sensitive topic, particularly in Europe, and that is why there are no events or text that explain any of the atrocities that were committed, or even more benign (relatively speaking) things they did with labor camps or rounding up factory workers and moving them around the Reich and its occupied territories.
Does that help you?
Indeed it would be nice to see something that explains the attitude of the German populace. It doesn't even need to include Nazi ideology - it's as simple as them feeling humiliated and wanting redemption, something I can relate to as a Pole.
Thanks for the feedback on my synopsis
