In 1944, Rudolf Kastner, a prominent Hungarian Zionist, bribed the Nazis into allowing 1,686 Jews safe passage to Switzerland. After the war, he came under fierce criticism from survivors for cooperating with the Nazis and failing to warn the rest of Hungarian Jewry of the fate that awaited them at Auschwitz. A libel suit launched against one of his detractors led to one of the first major discussions of the Holocaust in Israel’s public sphere. In 1957, Kastner was assassinated. Recalling his motivations at the time, his now-elderly assailant expresses regret for what he did:

Today, at eighty-one, and with the publication of his book, Quilt Blanket, Ze’ev Eckstein takes stock of his life for the last time and says: “I wouldn’t do it today. I wouldn’t shoot. There’s no doubt about it. . . . In what way did I pay a price? I murdered someone. I did something that takes me back to the entire Bible, back to Cain and Abel.”

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.
