Nazi America is obviously a much bigger problem, it's like Germany but worse.
Germany is small enough that if America was actually good, we could have overpowered and controlled the German population after world war 2.
But America isn't small. No country has any guaranteed chance of overpowering and controlling us.
It will probably be a long time before Nazi-style genocidal fascism is defeated. The biggest populations weren't good enough to deal with a Nazi Germany sized population before; today's biggest populations seem like they'll struggle to handle a tiny Israel sized population, let alone the bigger America sized population.
Feels like we're a long way from the dream of an overwhelming majority population "waking up" and reorganizing society into a stable, civilized system worldwide.
Kinda weird how we even keep instinctively seeing that as a possibility. But we do, so these are the areas we have to work hard on to make it happen
