Yes, it would help. It's been 70 years since WW2 ended and people are fast forgetting its lessons. Take an example, pretty much everyone agrees that ISIS uses the web as an online recruitment tool to radicalize young people and that they are very effective with it. This point is fairly non-controversial. Yet when the same point is made about extreme right-wing movements radicalizing young Americans, these concerns are largely not taken seriously. We expect our youth to be wise, discerning, able to think critically and immune to propaganda in a society that has steadily devalued education for decades.

"Hitler did nothing wrong" is a joke meme, until it isn't.
