History of Europe WWII

After learning about some history that lays in the past of Europe, I'd say I've learned enough about the whole WWII. It's really scary to think about the fact that once almost the whole of the European continent was invaded by Hitler and his Nazis. The idea of concentration camps are terrifying, and it's hard to grasp the realness of the whole situation, that real people had to go through all of that trauma. I'm glad that right now there is nothing currently going on like that, because I don't think I would know what to do at all.
