There is little doubt that if Hizballah had participated more intensively in Saturday’s attack, Israeli air defenses would have been pushed past their limits, and far more damage would have been done. Daniel Byman and Kenneth Pollack, trying to look at things from Tehran’s perspective, see this as an important sign of caution—but caution that shouldn’t be exaggerated:

Iran is well aware of the extent and capability of Israel’s air defenses. The scale of the strike was almost certainly designed to enable at least some of the attacking munitions to penetrate those defenses and cause some degree of damage. Their inability to do so was doubtless a disappointment to Tehran, but the Iranians can probably still console themselves that the attack was frightening for the Israeli people and alarming to their government. Iran probably hopes that it was unpleasant enough to give Israeli leaders pause the next time they consider an operation like the embassy strike.

Hizballah is Iran’s ace in the hole. With more than 150,000 rockets and missiles, the Lebanese militant group could overwhelm Israeli air defenses. . . . All of this reinforces the strategic assessment that Iran is not looking to escalate with Israel and is, in fact, working very hard to avoid escalation. . . . Still, Iran has crossed a Rubicon, although it may not recognize it. Iran had never struck Israel directly from its own territory before Saturday.

Byman and Pollack see here an important lesson for America:

What Saturday’s fireworks hopefully also illustrated is the danger of U.S. disengagement from the Middle East. . . . The latest round of violence shows why it is important for the United States to take the lead on pushing back on Iran and its proxies and bolstering U.S. allies.

For some time, opponents of U.S support for Israel have been urging the White House to end the war in Gaza, or simply calling for a ceasefire. Douglas Feith and Lewis Libby consider what such a result would actually entail:

Ending the war immediately would allow Hamas to survive and retain military and governing power. Leaving it in the area containing the Sinai-Gaza smuggling routes would ensure that Hamas can rearm. This is why Hamas leaders now plead for a ceasefire. A ceasefire will provide some relief for Gazans today, but a prolonged ceasefire will preserve Hamas’s bloody oppression of Gaza and make future wars with Israel inevitable.

For most Gazans, even when there is no hot war, Hamas’s dictatorship is a nightmarish tyranny. Hamas rule features the torture and murder of regime opponents, official corruption, extremist indoctrination of children, and misery for the population in general. Hamas diverts foreign aid and other resources from proper uses; instead of improving life for the mass of the people, it uses the funds to fight against Palestinians and Israelis.

Moreover, a Hamas-affiliated website warned Gazans last month against cooperating with Israel in securing and delivering the truckloads of aid flowing into the Strip. It promised to deal with those who do with “an iron fist.” In other words, if Hamas remains in power, it will begin torturing, imprisoning, or murdering those it deems collaborators the moment the war ends. Thereafter, Hamas will begin planning its next attack on Israel:

Hamas’s goals are to overshadow the Palestinian Authority, win control of the West Bank, and establish Hamas leadership over the Palestinian revolution. Hamas’s ultimate aim is to spark a regional war to obliterate Israel and, as Hamas leaders steadfastly maintain, fulfill a Quranic vision of killing all Jews.

Hamas planned for corpses of Palestinian babies and mothers to serve as the mainspring of its October 7 war plan. Hamas calculated it could survive a war against a superior Israeli force and energize enemies of Israel around the world. The key to both aims was arranging for grievous Palestinian civilian losses. . . . That element of Hamas’s war plan is working impressively.
