Please, this is in the DNA of America. Nazi Germany's lebensraum was directly inspired by the US' 19th century "Manifest Destiny" movement. Nazi Germany is just the egg that hatched, America is the hen still laying eggs wherever it goes; except this time the egg hatched in its own roost.
Correct and white supremacy goes hand in hand with colonizers youtu.be/g9HmV_-EE8g?...
I take it you never studied Nazi Germany, then?
Or even pre-WW2 Germany? You know,Weimar and HRE?
of course the Volkisch movement was inherently a racist movement, but its hardly anything unique amidst other "romantic" nationalist movements of the era. I'm saying you'd be gravely mistaken if you think the American eugenics and scientific racism movement wasn't a massive source of inspiration.
