Earlier this month, Kiev made headlines by banning “Stalingrad,” an award-winning book by Antony Beevor, an acclaimed British historian, on account of a single paragraphthat mentions a Ukrainian unit killing Jewish children. Poland’s ruling far-right Law and Justice Party proposed legislation making it illegal to accuse Poles of participating in the Holocaust, and targeted authors and journalists for daring to say otherwise. Once again, the Jews of Eastern Europe may face persecution and censorship for honoring their slain.
