In Nazi Germany, it was all the rage to make one’s town Judenfrei. Now a new fashion is sweeping Europe: to make one’s town or city what we might call “Zionistfrei”—free of the products and culture of the Jewish state. Across the Continent, cities and towns are declaring themselves “Israel-free zones,” insulating their citizens from Israeli produce and culture. It has ugly echoes of what happened 70 years ago.
