In that case I would argue that one shouldn't use North Koreans either. Though I honestly do feel this way. Sci-fi and fantasy give you this escape mechanism where you can talk about these issues without making it about race (well at least race in humans). We know Ender's Game and Starship Troopers are Cold War era books about Russians without them saying Russians or depicting them. There's a requisite maturity needed to read between the lines that hopefully one is able to distinguish between countries and races, despite correlations, by that point.
