In considering the Jewish legacy of the great philosopher, who was formally expelled by the Sephardi community of Amsterdam in 1656, Steven B. Smith urges that we focus less on his attempt to undermine the authority of Jewish scripture as on his fundamental, and highly costly, ideas about religion and politics:

Spinoza’s critical analysis of Judaism [that he puts forward in his Theologico-Political Treatise] did not grow out of self-hatred or anti-Judaism, but as a part of a project of liberalizing reform. His defense of the liberal state requires a religion that is itself quite liberal. He believed that the price of admission to this state entailed a radical secularization of Judaism both as a body of revealed law and as a distinctive way of life. His purpose was to strip all religions—both Judaism and Christianity—of their claims to exclusivity and reduce them to a handful of tenets that could provide the moral foundation of the modern state. Spinoza’s religion of reason would be stripped of all metaphysical claims that might give rise to controversy or could be used as a pretext for persecution.

Sound familiar?

The cost of admission to Spinoza’s state has been high. There is, as a famous economist once said, no such thing as a free lunch. The chief cost of Spinoza’s bargain has been the assimilation of Judaism, not to Christianity, but to liberalism. Indeed, for many Jews, Judaism has become virtually synonymous with support for liberal social causes. Even the expression “Jewish liberalism,” rather than a paradox, has become a commonplace. The result of this identification of Judaism with liberal values such as autonomy and emancipation has been the loss of both religious identity and fidelity to an ancient way of life. The Theologico-Political Treatise, it seems, may have eloquently defended freedom for Jews, but at the cost of what was specific to Judaism.

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.
