The University of California, Los Angeles has invited BDS-supporter Cornel West to be the keynote speaker at an event in honor of Abraham Joshua Heschel. In an open letter to West, Judea Pearl, a professor of computer science at UCLA, urges him to decline the invitation:

No matter how eloquent your speech and how crafty your words, the audience you will face at UCLA will not be able to take them too seriously in light of your recent decision to become a leading propagandist for the Boycott, Divestment, and Sanctions (BDS) movement. You have to forgive us for being pedantic in these matters, and perhaps not as flexible and nuanced as one might hope, but our history has taught us the importance of devising crisp and visible litmus tests to distinguish friends from foes. It so happens, and you know it as well as we do, that the term BDS has become our most reliable litmus test. In other words, we have come to equate promoters of BDS ideology with those who seek the destruction of Israel, hence the demise of the Jewish people.

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.
