On Saturday, a group of “yellow-vest” protestors in Paris recognized the philosopher and public intellectual Alain Finkielkraut and turned on him, yelling anti-Semitic epithets. Finkielkraut, who has never hesitated to identify himself as a Jew and a Zionist, has from its inception supported the yellow-vest movement’s criticism of Emmanuel Macron’s economic policies. But this was not the first or only instance of anti-Semitism in the movement—and elsewhere in Europe. Daniel Johnson comments:

As many as 44 percent of self-identified “yellow vests” believe that the world is ruled by Zionists. They see Macron as a puppet of his former employer, the Rothschild bank. Some 22 percent of the French public as a whole agrees with them. . . .

[A]ll over Europe, Jews repeatedly tell pollsters that they are experiencing anti-Semitism as a fact of everyday life. Many are considering emigration to Israel or the United States. None feels safe on a continent with a fast-growing Muslim population, many of whom have imported hostile attitudes toward Jews from their countries of origin. The problem, though, goes wider and deeper. Finkielkraut is among those to have criticized the European establishment for its craven attitude toward Islamists and its betrayal of Israel.

What is to be done? Clearly, Europe has done a lousy job of educating young people, whatever their origins. But we are also confused about how to go about this task. A distinguished Jewish academic in America recently told me that the constant reiteration of images of the Holocaust, reinforced by school visits to camps, museums, and memorials, might be counterproductive. “I don’t want people to be indoctrinated with the idea that the Jews can all be killed,” she said. “I want them to see that we are normal people, that Israel is a normal country, that Jews are neither victims nor manipulators, but just like everyone else.”

She has a point. It is essential that Europeans learn about the Holocaust, yet it is not enough. They also need to learn how Jews have survived and flourished since. And that means accepting and, yes, embracing the state of Israel as the Jewish homeland promised by the Balfour Declaration a century ago. A specter is haunting Europe—the specter of anti-Semitism. Unless it is exorcised, it will destroy us.

On Tuesday, a Hizballah drone attack injured three people in northern Israel. The next day, another attack, targeting an IDF base, injured eighteen people, six of them seriously, in Arab al-Amshe, also in the north. This second attack involved the simultaneous use of drones carrying explosives and guided antitank missiles. In both cases, the defensive systems that performed so successfully last weekend failed to stop the drones and missiles. Ron Ben-Yishai has a straightforward explanation as to why: the Lebanon-backed terrorist group is getting better at evading Israel defenses. He explains the three basis systems used to pilot these unmanned aircraft, and their practical effects:

These systems allow drones to act similarly to fighter jets, using “dead zones”—areas not visible to radar or other optical detection—to approach targets. They fly low initially, then ascend just before crashing and detonating on the target. The terrain of southern Lebanon is particularly conducive to such attacks.

But this requires skills that the terror group has honed over months of fighting against Israel. The latest attacks involved a large drone capable of carrying over 50 kg (110 lbs.) of explosives. The terrorists have likely analyzed Israel’s alert and interception systems, recognizing that shooting down their drones requires early detection to allow sufficient time for launching interceptors.

The IDF tries to detect any incoming drones on its radar, as it had done prior to the war. Despite Hizballah’s learning curve, the IDF’s technological edge offers an advantage. However, the military must recognize that any measure it takes is quickly observed and analyzed, and even the most effective defenses can be incomplete. The terrain near the Lebanon-Israel border continues to pose a challenge, necessitating technological solutions and significant financial investment.
