German Chauvinism Or National Statesmanship?

So I have this theory. Germans have been at the center of multiple conflicts in the world. Two of the most notable were during WWI under Kaiser Wilhelm and then again in WWII under Hitler. That this event happened so close together in time really raised an important question. Was Hitler just crazy or was he a normal German statesman, following a preconceived notion of what it means to be German and expanding it borders and preserving the idea of Germany, both physically and in the imaginations of the world? While we now consider it to be former, what if German culture naturally cultivated this idea of statesmanship in terms of expansion and taking over anyone that gets in the way?

Can this be applied to America as well? After all, a large portion of early European settlers were of Germanic descent and this is still heavily reflected today. Can the racism and Manifest Destiny seen in our own country be in fact a result of this notion of being German? The actions committed by whites in this country against people of color has been quite horrific. And while actions against other groups isn't solely a white issue, given the commonality in ethnic groups, can the ways that actions in the US and Europe and their similarities come in account due to ethnic and cultural similarities?

This is a theory I'm beginning to explore and I hope to write more about it in the future.
