You honestly have difficulty keeping track of the conversation.
You said: That’s far from the only thing the Germans have done wrong.
You implied that Germans have been the chief aggressors for centuries, when in truth, they waged wars of aggression over a roughly 30 year period (1914-45) -- and even during that time they were not the only ones.
That started with Bismarck’s wars of unification in the 1860s. Earlier, the French had been the big disruptors and disturbers of Europe’s peace, but Frederick the Great’s armies had been quite effective. Prussia punched above its weight class.
