Comparing current U.S. negotiations with Iran to American dealings with the Soviet Union from the 1950s through the 1980s, Natan Sharansky notes a key difference: during the cold war, the U.S. was willing to walk away from the table in response to Soviet aggression, demanded substantive concessions from Moscow, and took a stand for the human rights of Soviet citizens. When it comes to Iran, not so:

While negotiating with the Soviet Union, U.S. administrations of all stripes felt certain of the moral superiority of their political system over the Soviet one. They felt they were speaking in the name of their people and the free world as a whole, while the leaders of the Soviet regime could speak for no one but themselves and the declining number of true believers still loyal to their ideology.

But in today’s postmodern world, when asserting the superiority of liberal democracy over other regimes seems like the quaint relic of a colonialist past, even the United States appears to have lost the courage of its convictions.

We have yet to see the full consequences of this moral diffidence, but one thing is clear: the loss of America’s self-assured global leadership threatens not only the United States and Israel but also the people of Iran and a growing number of others living under Tehran’s increasingly emboldened rule. Although the hour is growing late, there is still time to change course—before the effects grow more catastrophic still.

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.
