Just that most of those “powerful” countries who weren’t directly affected didn’t give a fuck until Pearl Harbor happened including the USA and Canada who both knew damn well what was happening in Germany because tourists brought back stories and videos. And then they only declared war against Germany because Japan had a pact with Germany that said if someone declares war on you, they also declare war on me. I’m pretty damn sure they would have continued to look the other way otherwise but I guess North America still believes the we won the war story… however Germany lost. Minor important difference.
Hitler went down for many reasons… and at the end of the day it took remind me again, how many countries to bring down one?
