In his speech to the UN General Assembly on Tuesday, Joe Biden addressed a host of international issues, mentioning, inter alia, the “positive and practical impacts” resulting from “Israel’s greater normalization and economic connection with its neighbors.” He then added that the U.S. will “continue to work tirelessly to support a just and lasting peace between the Israelis and Palestinians—two states for two peoples.” Zach Kessel experiences some déjà vu:

Let’s take a stroll down memory lane and review how past U.S.-brokered talks between Jerusalem and [Palestinian leaders] have gone down, starting with 1991’s Madrid Conference, organized by then-President George H.W. Bush. . . . Though the talks, which continued through the next year, didn’t get anywhere concrete, many U.S. officials and observers across the world were heartened by the fact that Madrid was the first time representatives of both sides had met face to face. And then Palestinian militants carried out the first suicide bombing in the history of the conflict.

Then, in 1993, Bill Clinton tried his hand with the Oslo Accords:

In the period of time directly after the Oslo Accords . . . suicide bombings on buses and in crowded public spaces became par for the course. Clinton invited then-Palestinian Authority chairman Yasir Arafat and then-Israeli prime minister Ehud Barak to Camp David in 2000, hoping finally to put the conflict to rest. Arafat, who quite clearly aimed to extract as many concessions as possible from the Israelis without ever intending to agree to any deal—without even putting a counteroffer on the table—scuttled any possibility of peace. Of course, that’s not the most consequential event for the conflict that occurred in 2000. Soon after the Camp David Summit fell apart, the second intifada began.

Since Clinton, each U.S. president has entered office hoping to put together the puzzle that is an outcome acceptable to both sides, and each has failed. . . . Every time a deal has seemed to have legs, something happens—usually terrorist violence—and potential bargains are scrapped. What, then, makes Biden think this time will be any different?

When the IDF finally caught up with the late Hamas leader Yahya Sinwar, he wasn’t deep inside a subterranean lair, as many had expected, but moving around the streets the Rafah. Israeli forces had driven him out of whatever tunnel he had been hiding in and he could only get to another tunnel via the surface. Likewise, Israel hasn’t returned to fight in northern Gaza because its previous operations failed, but because of its success in forcing Hamas out of the tunnels and onto the surface, where the IDF can attack it more easily. Thus maps of the progress of the fighting show only half the story, not accounting for the simultaneous battle belowground.

At the beginning of the war, various options were floated in the press and by military and political leaders about how to deal with the problem posed by the tunnels: destroying them from the air, cutting off electricity and supplies so that they became uninhabitable, flooding them, and even creating offensive tunnels from which to burrow into them. These tactics proved impracticable or insufficient, but the IDF eventually developed methods that worked.

John Spencer, America’s leading expert on urban warfare, explains how. First, he notes the unprecedented size and complexity of the underground network, which served both a strategic and tactical purpose:

The Hamas underground network, often called the “Gaza metro,” includes between 350 and 450 miles of tunnels and bunkers at depths ranging from just beneath apartment complexes, mosques, schools, hospitals, and other civilian structures to over 200 feet underground. . . . The tunnels gave Hamas the ability to control the initiative of most battles in Gaza.

One elite unit, commanded by Brigadier-General Dan Goldfus, led the way in devising countermeasures:

General Goldfus developed a plan to enter Hamas’s tunnels without Hamas knowing his soldiers were there. . . . General Goldfus’s division headquarters refined the ability to control forces moving underground with the tempo of the surface forces. Incrementally, the division refined its tactics to the point its soldiers were conducting raids with separate brigades attacking on the surface while more than one subterranean force maneuvered on the same enemy underground. . . . They had turned tunnels from obstacles controlled by the defending enemy into maneuver corridors for the attacker.

This operational approach, Spencer explains, is “unlike that of any other military in modern history.” Later, Goldfus’s division was moved north to take on the hundreds of miles of tunnels built by Hizballah. The U.S. will have much to learn from these exploits, as China, Iran, and North Korea have all developed underground defenses of their own.
