Damn I am fucking ignorant as fuck on WWII I had no idea. I really don't remember them teaching it in school to even this extent.
And this is why they attack our schools and libraries and books. They want the voting public ignorant as possible so we are blind and easily manipulated. Those in power now (aka with wealth) won't have their kids and grandkids impacted, and that's about as far away from themselves they can care about.
If you're into physics or chemistry at all, The Making of the Atomic Bomb has a ton of WW1 and WW2 history in it and a surprising amount of info on Hitler. It's really long but it's on Audible as well.
