In January 1957, National Review, then less than a year old, published a letter by Leo Strauss denouncing what he saw as the magazine’s anti-Israel stance and arguing that conservatives ought to support the Jewish state. Steven B. Smith extracts some important lessons for dealing with present-day assaults on Israel’s legitimacy:

Revealingly, Strauss never invokes the Holocaust as the reason for Israel’s existence. He refuses to treat causes that either highlight Jewish weakness or appeal to European guilt. If Israel is to stand, it must stand on its own two feet, that is, from sources within its own tradition.

The best reply to the deniers and delegitimizers is a serious engagement with the founding texts of Zionism—Theodor Herzl, Max Nordau, Aḥad Ha’am, Vladimir Jabotinsky. These are to Israel’s lifeblood what the Declaration of Independence and the Federalist Papers are to American self-understanding. Strauss points to the conditions of human dignity that can be attained only by a self-governing people capable of determining their fate while remaining loyal to their heritage. Israelis and, just as important, Americans trying to defend Israel must never shrink from this task.

Israel will likely respond directly against Iran after yesterday’s attack, and has made known that it will calibrate its retaliation based not on the extent of the damage, but on the scale of the attack. The specifics are anyone’s guess, but Edward Luttwak has a suggestion, put forth in an article published just hours before the missile barrage: cut off Tehran’s ability to send money and arms to Shiite Arab militias.

In practice, most of this cash comes from a single source: oil. . . . In other words, the flow of dollars that sustains Israel’s enemies, and which has caused so much trouble to Western interests from the Syrian desert to the Red Sea, emanates almost entirely from the oil loaded onto tankers at the export terminal on Khark Island, a speck of land about 25 kilometers off Iran’s southern coast. Benjamin Netanyahu warned in his recent speech to the UN General Assembly that Israel’s “long arm” can reach them too. Indeed, Khark’s location in the Persian Gulf is relatively close. At 1,516 kilometers from Israel’s main airbase, it’s far closer than the Houthis’ main oil import terminal at Hodeida in Yemen—a place that was destroyed by Israeli jets in July, and attacked again [on Sunday].
