In my US Classes, he was always a hero as well. We were taught that Neville Chamberlain kept concedingnthings to Hitler in hopesntht being nice would sway him, and when it didn’t, Brits got mad and voted in tough guy Churchill who really gave em the business. Stalin was a Nazi ally until the Nazis betrayed him, and that stopped the bleeding, then Roosevelt declared war after Pearl Harbor and the US won the war for the Allies.
