The Obama administration’s ongoing pique over Netanyahu’s upcoming speech to Congress is not over protocol, argues Elliott Abrams. Rather, the White House has specific reasons for deliberately encouraging a spat with Israel. Most disturbingly, it wishes “to use the current tension to harm Israel’s support in the United States permanently.” Abrams writes:

All opinion polls in the last several years show a partisan edge in support: overall support for Israel is steady and high, but its composition is changing. More and more Republicans support Israel, and the gap between Democratic and Republican support levels is growing. President Obama acts as if he sees this as a terrific development, one that should be enlarged as much as possible before he leaves office. That way he would leave behind not just an Iran deal, but weakened support for Israel on Iran and everything else. Support for Israel would become less of a bipartisan matter and more a divisive issue between the two parties. It is not hard to envision Obama in retirement joining Jimmy Carter as a frequent critic of Israel, pushing the Democratic party to move away from its decades of very strong support for the Jewish state.

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.
