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.

While the current Egyptian president, Abdel Fattah el-Sisi, has never been friendly to Hamas, his government has objected strenuously to the Israeli campaign in the southernmost part of the Gaza Strip. Haisam Hassanein explains why:

Cairo has long been playing a double game, holding Hamas terrorists near while simultaneously trying to appear helpful to the United States and Israel. Israel taking control of Rafah threatens Egypt’s ability to exploit the chaos in Gaza, both to generate profits for regime insiders and so Cairo can pose as an indispensable mediator and preserve access to U.S. money and arms.

Egyptian security officials have looked the other way while Hamas and other Palestinian militants dug tunnels on the Egyptian-Gaza border. That gave Cairo the ability to use the situation in Gaza as a tool for regional influence and to ensure Egypt’s role in the Palestinian-Israeli conflict would not be eclipsed by regional competitors such as Qatar and Turkey.

Some elements close to the Sisi regime have benefited from Hamas control over Gaza and the Rafah crossing. Media reports indicate an Egyptian company run by one of Sisi’s close allies is making hundreds of millions of dollars by taxing Gazans fleeing the current conflict.

Moreover, writes Judith Miller, the Gaza war has been a godsend to the entire Egyptian economy, which was in dire straits last fall. Since October 7, the International Monetary Fund has given the country a much-needed injection of cash, since the U.S. and other Western countries believe it is a necessary intermediary and stabilizing force. Cairo therefore sees the continuation of the war, rather than an Israeli victory, as most desirable. Hassanein concludes:

Adding to its financial incentive, the Sisi regime views the Rafah crossing as a crucial card in preserving Cairo’s regional standing. Holding it increases Egypt’s relevance to countries that want to send aid to the Palestinians and ensures Washington stays quiet about Egypt’s gross human-rights violations so it can maintain a stable flow of U.S. assistance and weaponry. . . . No serious effort to turn the page on Hamas will yield the desired results without cutting this umbilical cord between the Sisi regime and Hamas.
