I was reading up on "Manifest Destiny" and it suddenly struck me how similar the ideas between it and "Lebensraum" seem at first glance. I've heard and read before that the Nazis were inspired in their ideology and cruelty by American ideas/trends/wrongdoings, like eugenics and the "Trail of Tears". Would this also extend to the concept of "Manifest Destiny"? From a Laymen's perspective, both ideas suppose the perpetrators to be racially (and religiously, for Americans) superior to the people living on the lands they aim to conquer, and thus entitled to that land. Or was "Lebensraum" more inspired by the European migrations of centuries past? Lastly, if there hadn't been a "Manifest Destiny", what are the chances of an idea like "Lebensraum" being created on its own?
