Charles Krauthammer notes the return of anti-semitism to Europe.

The hiatus is over. Jew-hatred is back, recapitulating the past with impressive zeal. Italians protesting Gaza handed out leaflets calling for a boycott of Jewish merchants. As in the 1930s. A widely popular French comedian has introduced a variant of the Nazi salute. In Berlin, Gaza brought out a mob chanting, "Jew, Jew, cowardly pig, come out and fight alone!" Berlin, mind you.

European anti-Semitism is not a Jewish problem, however. It's a European problem, a stain, a disease of which Europe is congenitally unable to rid itself.
