It’s not naive. I’ve served in the military. You don’t constantly have a massive army behind you telling you to push forward. You’re sent out in squads. Patriotism and brotherhood is how this has always been overcome, because war is scary and hard. I don’t see the people of NK feeling much of either if they aren’t taken care of and are finding out how much they were lied to.
Also the fact you gotta hide that you’re filming your own army and allies should maybe be a clue you’re on the wrong side.
