It really seems like the living memory is the only reall window in which one can hope for a lesson humanity learns to persist. It's not lost on me the very last few people who remember WW2 are approaching zero by the day, and the closer to 0 living that number gets, the more violently capable fascism seems to be at re-asserting itself.

Shame the cold war is so much further than that from exiting living memory - every generation that grew up under duck and cover drills can't be redeemed.
