Whenever Jews are killed or beaten, on 7 October or last night in Amsterdam, well-meaning sorts solemnly intone that this latest outrage must be a ‘wake-up call’ about the threat of anti-Semitism.

Ah, the Wake-Up Call. Much vaunted, long awaited, never heard. There have been no shortage of wake-up calls. Off the top of my head, there has been 7 October, Neve Yaakov, Monsey, the 2019 New York attacks, Poway, Jersey City, Pittsburgh, the stabbing intifada, Hypercache, Kehilat Yaakov, Merkaz HaRav, and the second intifada.
