Recent street violence in Amsterdam reveals profound changes in how the left and right deal with antisemitism. For European Jews, it’s a strange new world.

Some fans told the BBC that they were ordered to show their passports before being beaten. Two Jewish British men said they intervened in an assault to help an Israeli man to his feet, telling the attackers they were British, but they were still punched for “helping the Jew.”

Police in the Dutch capital are investigating how the assaults last week in Amsterdam against Israeli soccer fans were coordinated.
