The war in Gaza has been accompanied by an increase in anti-Semitism in Europe. In July mobs attacked two different synagogues in Paris, and in the same month anti-Semitic incidents doubled in Britain. The attacks on Jews and Jewish establishments came largely from Muslims upset about what is happening in Gaza. Even before this conflict, anti-Semitism has been on the rise, with the worst expressions of it in France, Hungary, and Belgium. A hopeful sign is that in some places moderate Muslim leaders are working with Jewish leaders to stop campaigns to ban circumcision and ritual slaughter (Newsweek, July 29).
