At the annual Pro Musica Hebraica concert last week, the Amernet String Quartert, along with the mezzo-soprano Rachel Calloway and the guitarist Adam Levin, performed a series of pieces based on traditional Jewish melodies with their roots in medieval Spain. Grace Jean writes in her review:

Because Spanish Jews preserved their culture through oral traditions, Sephardi music was rarely written down, but rather passed between generations through singing. The composer Alberto Hemsi (1898–1975) sought to capture the songs he heard in his travels, ultimately publishing ten volumes of melodies.

Inspired by Hemsi’s efforts, the composer Ljova (Lev Zhurbin) . . . arranged “Blanca Nina,” a suite of traditional songs and ballads. For this world premiere, Calloway sang with haunting presence while Amernet proved an equal partner in depicting a young woman’s life in Sephardi Spain.

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.
