Shtetl Days by Harry Turtledove is a fascinating short story set in an alternative future where the Nazis have won WW2 and conquered the world. They succeeded in exterminating the Jews but have set up recreated shtetls as tourist destinations. Actors play at living the daily lives of the long destroyed Jews to the delight of on-lookers snapping photos. They even re-enact pogroms! Nevertheless, the law of unintended consequences kicks in and some of the actors begin to wonder which part of their life is just a role being played.
