The holiday of Purim, which began last night and continues today, is one of the most joyous days of the Jewish calendar, traditionally celebrated with carnival-like merriment. Yet, notes Meir Soloveichik, the story behind the holiday—recorded in the book of Esther—is an ominous one, in which a king cavalierly assents to a proposal of genocide on the part of his chief adviser and then, on the turn of a dime, changes his mind and has the adviser hanged:

The disquieting conclusion of Esther’s tale was eloquently described by my great-uncle, Rabbi Joseph B. Soloveitchik. “If a prime minister who just yesterday enjoyed the full confidence and trust of the king was suddenly convicted and executed,” he reflected, “then who is wise and clairvoyant enough to assure us that the same unreasonable, absurd, neurotic change of mood and mind will not repeat itself?” The Purim tale reminds us that a government, and the society it oversees, can turn against its most vulnerable in a matter of moments. This is why, he argued, Esther’s story is no triumphal tale; on the contrary, it is “the book of the vulnerability of man in general and specifically of the vulnerability of the Jew.”

Why, then, all the joy?

Here we must understand how different the book of Esther is from every other book in the Hebrew Bible. In this tale no mention is made of the divine; the Jews inhabit a world devoid of revelation. Whereas in every other scriptural tale political engagements take place under prophetic instruction, in the Persian court God gives no guidance to the Jews facing a terrible danger. Esther, Rabbi Soloveitchik wrote, faced an unprecedented question: “How can the Jew triumph over his adversaries and enemies if God has stopped speaking to him, if the cryptic messages he receives remain unintelligible and incomprehensible?”

In this sense, Esther is the first biblical figure, male or female, to engage in statesmanship. Previous heroes—Moses and Elijah, Samuel and Deborah—are prophets who are guided and guarded by the Divine, but Esther operates on instinct, reflecting a mastery of realpolitik.

Purim thus marks the fragility of Jewish security, but also the possibility of heroism in the face of this vulnerability. It is therefore a holiday for our time. Around the world, and especially in a Europe that should know better, anti-Semitism has made itself manifest once again. As Esther’s example is celebrated, and Jews gather in synagogue to study her terrifying tale, we are reminded why, in the face of hate, we remain vigilant—and why we continue to celebrate joyously all the same.

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.
