Earlier this month, terrorists in Gaza resumed firing rockets and mortars at Israel and met with swift, if limited, counterattacks from the Israel Air Force. While Israel’s response seems to have stopped the attacks for the time being, critics are already murmuring about Jerusalem’s supposedly disproportionate response and alleged violation of international law. Louis René Beres explains that it is Hamas, not Israel, that has violated international law by committing the war crime known as “perfidy,” i.e., using its own civilians as human shields:

Hamas’s intent [is] to incriminate the Israelis as murderers of Gaza’s civilians. Legally, however, the net effect of Arab perfidy in Gaza is to free Israel of all responsibility for Arab harm, even if it is Israeli retaliatory fire that actually injures or kills the Gazan victims. Under law, those Arab residents who suffer from Israeli retaliations are incurring the consequences of their own government’s war crimes. Palestinian suffering, which we are surely about to see again in stepped-up, choreographed Arab propaganda videos, remains the direct result of a relentlessly cruel, insensitive, and criminal Hamas leadership.

Significant, too, although never really mentioned, is that this Hamas leadership . . . often sits safely away from Gaza, tucked away inconspicuously in Qatar. For these markedly unheroic figures, “martyrdom” is allegedly always welcomed and revered, but only as long as that singular honor is actually conferred upon someone else.

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.
