Hitler learned about Eugenics from America. We were forcibly sterilizing people for being “inferior” which you can imagine who that meant. America built their own concentration camps for Japanese citizens and our forced labor in our current prison system is just tge more pletable version of labor camps.
The American civil war was about slavery, but tge north was not full of abolitionist people like you might assume. Tge rich in the North and South were against ending slavery, but their hands were forced by the larger population. The only reason we have not had nukes go off is only because they are old and not maintained well. We’ve dropped a few nukes on accident that just didn’t go off. At least two of those were over America.
