Last week, Nikki Haley announced that she will be stepping down as the U.S. ambassador to the United Nations at the end of the year. When President Trump appointed her to the position, she had behind her a successful tenure as governor of South Carolina, but no prior experience in foreign policy. This, writes Seth Lispky, turned out to have been her greatest asset:

What a contrast [Haley provided] to the string of ambassadors who fell on their faces in the swamp of Turtle Bay. That’s particularly true of the two envoys under President Barack Obama. [The] “experienced” hands who came before her proceeded to fail. Their key misconception was the notion that the United Nations is part of the solution to the world’s thorniest problems. Its charter was a vast treaty designed by diplomats to achieve “peace,” “security,” and “harmony.”

What hogwash.

Haley, by contrast, may have come in without experience—but that meant she also lacked for illusions. What a difference when someone knows that they’re in a viper pit—that the UN is itself the problem. And has the gumption to say so.

This became apparent the instant Haley opened her first press conference, [in which she said of the UN’s obsessive fixation on condemning the Jewish state]: “I am here to say the United States will not turn a blind eye to this anymore. I am here to underscore the ironclad support of the United States for Israel. . . . I am here to emphasize that the United States is determined to stand up to the UN’s anti-Israel bias.”

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.
