You’re right they don’t learn from their mistakes or learn from the past, which is why every time fascists like them rear their ugly heads in any society, they engage in the exact same tactics they engaged in last time. They might last for a little while but eventually people get tired of their crap and they always lose(especially when we fight back). They’ve lost every single time we’ve fought them. But like you said, they don’t learn and keep trying the same thing over and over throughout the decades and expecting a different result.
