Wars, hot or cold, are also missing from standard science fiction versions of the future. Interplanetary wars don’t count, and neither do wars with robots or zombies. I mean wars among nation-states or global alliances or regional blocs. George Orwell’s 1984, inspired in part by James Burnham’s The Managerial Revolution, imagined a world divided among three totalitarian blocs: Oceania, Eurasia, and Eastasia. I can’t think of any other well-known examples of geopolitics in science fiction.
— Michael Lind. Everything that Lind says is missing from SF may be found in, to cite just one example among many possible ones, the work of Ursula K. LeGuin. Given that LeGuin is one of the most famous SF writers in the world, and Lind appears not to be familiar with her work, then perhaps his declarations about what SF does and does not do should be taken with a truckload of salt.
