... But you started it, ironically enough.
Anyway, the true point of this thread still stands: If the UN had been founded as a fascist or communist organization instead of a liberal one, wouldn't it want to enforce a different set of civics? Or do we view the idea of all the nations of the world coming together to vote on things as inherently liberal? While it seems unlikely that a successful Nazi Germany would have come up with a similar idea, a communist alt-history UN could easily be imagined.
Imo banning specific civics instead of enforcing them would be more realistic at least.
