The idea that its downfall into fascism would not have knock-on effects around the world, and that all the ‘good’ people could escape it to greener pastures, is very shortsighted and more than a little naive. It was not destiny that Germany became fascistic, Hitler didn’t even win the popular vote. The knock on effects of the fascists being allowed to win was absolutely devastating the world over. Why would the US becoming full blown fascist be any different?
