Antisemitism in the twenty-first century remains a major threat to Jewish communities around the world, and a potent challenge to the liberal international order. But it can so often be a more hidden form of racism, relying on codes, images, cues, and ciphers embedded in the cultural mythology of prejudice against Jews. It is about the invocation of the blood libel, attacks on so-called “cosmopolitans,” accusations of “dual loyalty,” and conspiratorial notions of malign “Jewish power.” It is also a highly protean prejudice, ever adaptable to a multitude of changes in political and social circumstances, always ready to mutate and shape-shift to fit a new environment. That is why it has so easily become a feature of the modern anti-Israel movement. In this short volume, Jeremy Havardi explores how anti-Israelism has reproduced many of the canards, tropes, and ciphers of historic Jew-hatred and regurgitated them as attacks on Zionism and Israel. Today, the “Jewish question” has been replaced by the “Israel question,” with a similarly obsessive and ritualistic form of demonization and delegitimization. Anyone concerned about the future of liberal democracy should take note.
