I'm making a story set in a Post-Apocalyptic future, and I wanted to have a a country as the antagonist of the story. At first I wanted it to be China (symbolic of the Rise of China), but I don't want to step on anyones toes. So I was thinking about using Nazi's (as they're generally disliked). I could also use fantasy counterpart cultures, but I wanted to set it in the real world. My gut feeling is telling me to go with China, but I'm not sure what to do here. I'd like some oppinions please. Thanks.
