Last week—not long after Hamas and Fatah signed a reconciliation agreement in Egypt—Saleh Arouri, the deputy chairman of Hamas’s politburo, led a delegation to Tehran where they met with high-ranking politicians. Khaled Abu Toameh comments:

Hamas also sees the visit of its top officials to Tehran as a rejection of Israel’s demand that it cut off its ties with Iran. Hamas officials say they continue to see their relations with Iran as “strategic and significant,” especially in wake of Tehran’s financial and military aid to their movement in the Gaza Strip.

By aligning itself with Iran, Hamas is also seeking to resist any demand that it abandon its ideology and charter, which call for the destruction of Israel and oppose any peace process between Israelis and Palestinians.

Iranian officials apparently do not like Mahmoud Abbas and the Palestinian Authority and are not keen on seeing them return to the Gaza Strip. . . . Abbas, for his part, has always considered Iran a threat to his regime as well as to stability in the region. In the past, he has criticized Iran for “meddling” in the internal affairs of the Palestinians by supporting Hamas and Palestinian Islamic Jihad in the Gaza. . . .

The Egyptians, who played a major role in brokering the Hamas-Fatah deal, are also believed to be worried about Iran’s renewed meddling in the internal affairs of the Palestinians. Both the Palestinian Authority and Egypt see the visit of the Hamas delegation to Iran as a serious setback to the “reconciliation” agreement and as a sign that Hamas is not sincere about implementing the accord.

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.
