So I watched the BBC series called the Dark Charisma of Hitler. The Germans really were sons of bitches back then and they rolled over Europe without much resistance. No their biggest error was invading Russia, a lesson they could have taken from Napoleon.
So another suggested video was about how the Czechoslovakian people after the conclusion of World War II – they persecuted the Germans in the Sudetenland. Part of me says the Germans got what they deserved.
