Last week, Israeli Prime Minister Netanyahu took a pasting from pundits and even some Jewish leaders when he reacted to the attack on Copenhagen synagogue by repeating his call for European Jews to “come home” to Israel. Many people were uncomfortable with the prime minister’s open advocacy for Zionism. But the problem goes deeper than that. Despite the recent violence against Jews in Paris and Copenhagen, denial about what even the U.S. State Department has termed a “rising tide” of anti-Semitism still exists. But yesterday’s comments by a German Jewish leader advising fellow Jews not to identify themselves by wearing yarmulkes while walking in certain sections of the country is yet more confirmation that what Europe is experiencing is a revival of Jew hatred that can’t be ignored. If Jews must live in fear even in a country that supposedly has learned the lessons of the Holocaust, then what hope is there for Jews on the Continent other than to seek protection elsewhere.

A new Pew Research Center study shows that Jews were harassed or oppressed by their governments in 77 of the 198 countries covered by the survey. That includes a frightening total of 34 out of 45 countries in Europe. Yet the problem with accepting the reality of European anti-Semitism arises from a reluctance to place the blame for this prejudice on the haters rather than the victims.

One example came this week from “Science Guy” Bill Nye, the popular science educator and television star. On Bill Maher’s HBO show Real TimeNye said that the problems of European Jews stem from their reluctance to make friends with those who hated them. Attacking Netanyahu’s Zionist stand, Nye said the answer was that Jews should do more “to get to know their neighbors,” as if the roots of centuries of European anti-Semitism was the unwillingness of the victims to undertake outreach to anti-Semites.

That was offensive enough, but an even better example of the mentality that tolerates this new wave of anti-Semitism came from a British Jews. Harry Potter Actress Miriam Margolyes told the Guardian, “I don’t think people like Jews” but blamed the current outbreak on Israel since it gave Britons an excuse to vent their true feelings because of anger about the Gaza war. Like most British artists Margolyes blamed Israel for defending itself against Hamas terrorism and said the backlash against Jews was therefore somehow understandable, if deplorable. Her stance was both uninformed and illogical but it reflects the attitudes of English and other European elites who have, in a strange confluence of opinion, come to share the prejudices of Muslim immigrants who have helped revive traditional Jew hatred on the continent.

Blaming the Jews for being clannish (the conceit of Nye’s bizarre comments) sounds more like 19th century anti-Semitism, but even if we only focus on the way anti-Zionism has allowed traditional hatred to undergo a revival, there is no longer much doubt about the fact that it is becoming open season on Jews on the streets of Europe. A viral video of a Jewish journalist strolling through Paris wearing a kippah being abused by passersby is one more confirmation of a trend that can only be denied by those with ulterior motives.

European Jews may still prefer to think of themselves as safe, free, and prosperous and the political leaders of their countries may often say the right thing about anti-Semitism. But if Jews can no longer walk the streets of Europe’s capitals while identifying themselves with their faith or fear to speak out in defense of Israel lest they face opprobrium, then they cannot pretend to be truly free. The choice whether to stay or to go is personal, and it is difficult for anyone to pick up and leave their homes even under duress. But, as it did throughout the 20th century, history continues to vindicate the cause of Zionism. The Jews of Europe cannot pretend to be secure or to be confident that worse is not in store for them. Netanyahu was right to speak up about them having a haven where they will be able to defend themselves. Those inclined to denigrate his remarks should stroll about Europe’s streets while identifying themselves as Jews before they speak.
