As Cathy Young explains in vivid detail over at Slate, numerous sci-fi novels published in the early 2000s — War 2010: The Ukrainian Front, War 2011: Against NATO, Omega, Battlefield Ukraine: The Broken Trident, among them — describe scenarios in which Ukraine becomes a battleground between Russian separatists and Ukraine nationalists backed by the US and NATO. Several authors of those books, most notably Fedor Berezin (of War 2010 and War 2011), have since gone on to play active roles in the conflict itself, with Berezin aggressively propagandizing on behalf of Russian separatists in Ukraine. How the conflict evolves remains to be seen, but some critics accuse the sci-fi writers of creating a fertile environment for the conflict to take root in the first place. In any case, it's a particularly worrisome example of life imitating art more than the other way around.
