Opinion | The Left’s Anti-Semitism Crisis Is the Right’s Opportunity

Wars have a way of scrambling politics near and far, and so it may become with the war Hamas has launched against Israel. One topsy-turvy outcome in Europe is that ostensibly anti-Semitic parties on the further reaches of the political right have embraced Israel—likely because they’ve realized that doing so emphasizes the left’s embarrassing anti-Semitic hypocrisies.

In France, representatives of the two main right-wing political movements—those led by Marine Le Pen and Eric Zemmour—participated in a pro-Israel rally days after the attack. Ms. Le Pen in the National Assembly last week expressed solidarity with Israel, describing Hamas’s attack as a “pogrom,” and reminding lawmakers of the need to “protect French Jews.”
