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].

Examining the effects of Iran’s decision to launch nearly 200 ballistic missiles at Israel on October 1, Benny Morris takes stock of the Jewish state’s strategic situation:

The massive Iranian attack has turned what began as a local war in and around the Gaza Strip and then expanded into a Hamas–Hizballah–Houthi–Israeli war [into] a regional war with wide and possibly calamitous international repercussions.

Before the Iranians launched their attack, Washington warned Tehran to desist (“don’t,” in President Biden’s phrase), and Israel itself had reportedly cautioned the Iranians secretly that such an attack would trigger a devastating Israeli counterstrike. But a much-humiliated Iran went ahead, nonetheless.

For Israel, the way forward seems to lie in an expansion of the war—in the north or south or both—until the country attains some sort of victory, or a diplomatic settlement is reached. A “victory” would mean forcing Hizballah to cease fire in exchange, say, for a cessation of the IDF bombing campaign and withdrawal to the international border, or forcing Iran, after suffering real pain from IDF attacks, to cease its attacks and rein in its proxies: Hizballah, Hamas, and the Houthis.

At the same time, writes Morris, a victory along such lines would still have its limits:

An IDF withdrawal from southern Lebanon and a cessation of Israeli air-force bombing would result in Hizballah’s resurgence and its re-investment of southern Lebanon down to the border. Neither the Americans nor the French nor the UN nor the Lebanese army—many of whose troops are Shiites who support Hizballah—would fight them.
