That stuff would be like a kid's show referencing ISIS, North Korea or Putin-not gonna happen. It's too controversial and heavy a topic for a children's show.
ISIS, definitely not, Putin, I guess more Russian villains, but North Korea seems like they might make for good children's villains, since a greedy loudmouthed fat guy who makes everyone worship him ("or else") and has everyone praise him despite his obvious lack of any redeeming traits seems like it'd make a good villain in a kids' show.
