For years, Iran was the chief sponsor of Hamas, supplying it with cash and arms. But when the terrorist group chose to oppose Bashar al-Assad, Tehran’s client, in the Syrian civil war, the ayatollahs shifted their support to Islamic Jihad, with which they soon had a similar falling-out. After trying to cultivate an alternative to both, the Islamic Republic is now reconciling with Islamic Jihad, as Khaled Abu Toameh explains:

For now, Iran is not prepared fully to bring Hamas back under its wing. Hamas, for the Iranians, is a “treacherous” movement, thanks to its periodic temporary ceasefires with Israel. The Iranian leaders want to see Hamas killing Jews every day, with no break. Ironically, it has become too “moderate” for the Iranian leadership. . . .

Whatever Iran’s intentions may be, one thing is clear: the Iranians are taking advantage of the nuclear deal to move forward with their efforts to increase their influence over some Arab and Islamic countries. Iran is also showing that it remains very keen on playing a role in the Israel-Palestinian conflict—one that emboldens radical groups that are bent on the destruction of Israel and that share the same values as Islamic State.

Iran’s latest courtship of Islamic Jihad is yet another attempt by the mullahs to deepen their infiltration of the Palestinian arena by supporting and arming any terror group that strives to smash Israel. For now, it seems that [the] scheme is working, largely thanks to the apathy of the international community, where many believe that Iran has been declawed by the nuclear deal.

But more Palestinian terrorist leaders may soon perform the “pilgrimage” to their masters in Tehran. If this keeps up, the Iranians themselves will make any Palestinian state that is created in the region their puppet. Their ultimate task, after all, is to use that state as a launching pad to destroy Israel. And the Iranians are prepared to fund and arm any Palestinian group that is willing to help achieve this goal.

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.
