Somehow you sound entirely right-wing and modestly left-wing at the same time. Not in a “let gay married couples buy guns to protect their trans-friendly pot farm” way, but more of a “abortion should be legal for child sex slaves” kind of way. I’m presuming this was not intentional.

“Civilization”.may not be the word you’re looking for. Every UN member is part of the same “civilization”.in general usage, even the ones who really dislike each other. Maybe “nation”?
