(2) About the "Race of Warriors" thing, I assume that's either the author applying "power corrupts" once more OR referring to the original Germans (before the world wars) being somewhat of a mix between the germanic tribes, which made some living hell for the Romans, and the Norse, both of which had that Warrior culture thing going on. In that case it would be a cultural thing, which is completely fine and unproblematic.
Another thing, at the end the Zulu Empire (African) got one of Berengars b*st*rds (w/that goddess) on the throne, so they should be part of the great alliance too. Along with a Granada (Muslim-Arabic), Japan (Asian), The one Indian country...
I don't see your Racism here dude...
Yes, the German Empire is more advanced and keeping them as vassals, but those vassals all have the same tech standards. And the Nordic Kingdoms, which are demographically basically the same as the Germans are Vassals too, so treated the same. That would be "equal treatment" on countries
