Two Israeli embassy staff were murdered in a shooting outside a Jewish museum in Washington. The murderer shouted “Free Palestine” before opening fire. Our hearts are with the families and with the Jewish community in the United States. *dansenor* just tweeted that they feel like they are in Paris. It’s time to update that comparison. Over the past week, in the Jewish communities I visited and in conversations with thought leaders, I said I feel like a resident of the Land of Israel visiting Germany in the 1920s or 1930s. The well-meaning hosts ask about the situation back home - about the riots, the Arab revolt, the pogroms - while they themselves are sitting on a powder keg of antisemitism and anti-Israel hatred. What happened today is horrific. It must prompt serious reflection and action from both the U.S. government and the Jewish community. Chants of “Free Palestine” are not expressions of opposition to the occupation or political protest. They are the modern-day equivalent of the 19th-century German pogromists’ “Hep Hep” cries - and they must be treated accordingly.
