People were not having intellectual debates about Hitler’s motivations in the middle of World War II while he was roasting millions of Jews for dinner. The time for intellectual debate is a luxury reserved for after the conflict is over. You think slaves and freedom fighters like John Brown and Harriet Tubman were thinking about the rationale of the Confederates? Hell nah.
Of course people fighting on the ground in any conflict wont be having those debates, let alone while fukking war is going on around them. They will have very strong reasons to, years later, argue that "you had to be there to understand" as a discussion ender to any explanation or nuance being given in those luxury intellectual debates (which, again, makes total sense).
If people had internet connection and could talk to each other as easily as we can today, then you for sure would've had germans talking about what happened to them after WW1 and how a scenario were someone like Hitler could take control and open the door for the coming atrocities could happen.
HL has a bunch of threads about war and the only time I see people putting their hands up when nuanced discussions happen is when US interests are involved. As someone that's from south america, I'm all for reading and having a better understanding of these fukked up situations we are seeing
