Weisman’s book never overcomes this foundational flaw: It is based on the wildly inaccurate claim that American Jews are not talking about, thinking about, and calling out anti-Semitism. Weisman, alarmed by swirling hatred and lack of Jewish communal cohesion, seems to have cast about for someone to blame and settled on Jews themselves; his facts are wobbly and his prescriptions are thin. Yet the urgency of his project—finding a unified Jewish identity in a time of fracture, assimilation, and recurring bigotry—marks a development that has been unimaginable to Jews for two or three generations: Once again, hate toward Jews is rising. Once again, Jews are distressingly divided. Once again, there is no easy solution to protect Jews’ moral, political, or physical future.
