Learn From Gaza, Prepare For Hezbollah

By RICHARD NATONSKI and JONATHAN RUHE

With a ceasefire announced in Gaza, it’s crucial to apply the lessons-learned to a likely future conflict with Hezbollah, and likely Iran, in Lebanon and beyond.

As The Jewish Institute for National Security of America (JINSA) has laid out in a comprehensive report, this looming war will be unprecedentedly destructive. Hezbollah’s arsenals are an order of magnitude more potent than anything in Gaza, including at least 130,000 rockets and missiles that will do what Hamas conspicuously has yet to accomplish – namely, overpower Israel’s world-class multi-layered air defense network.

President Biden’s welcome decision last Thursday to replenish interceptor stocks for Israel’s short-range Iron Dome air defenses – which were called upon more than ever in the latest flareup – is only a small glimpse of what Israel will need to defend itself in the next war. In addition to Iron Dome, Washington must ensure adequate U.S.-Israel coproduction of David’s Sling and Arrow air defense systems that will be crucial for defending against Hezbollah’s and Iran’s much more sophisticated, powerful and longer-range projectiles, including precision munitions.

Since Hezbollah’s last war with Israel in 2006, Iran has assiduously rebuilt its primary terrorist proxy into a genuine juggernaut. Hezbollah now possesses more firepower than 95 percent of the world’s conventional militaries, and more rockets and missiles than all European NATO members combined. As is the case with terrorist groups in Gaza, the vast majority of these are unguided short-range rockets, though Hezbollah likely has several times more of these than the estimated 30,000 short-range rockets and mortars in Gaza at the start of the last round of conflict.

Hezbollah also has thousands of more powerful unguided medium- and long-range rockets, many of them ranging all of Israel, compared to several hundred at most in Gaza that can reach central Israel, including Tel Aviv, and only parts of the north. These longer ranges allow Hezbollah to disperse its arsenal throughout Lebanon, including Beirut and Beqaa Valley, covering much greater area than Gaza.

And unlike anything in the arsenals of Hamas or Palestinian Islamic Jihad, Hezbollah wields dozens or hundreds of precision missiles. Tehran also tries to proliferate technology to convert Hezbollah’s plentiful unguided rockets into precision weapons, and it assiduously attempts to make Syria, Iraq and Yemen into additional launchpads. Because Iron Dome focuses on projectiles threatening built-up areas, Israel’s challenges will grow proportionally with the precision munition stocks of Iran, Hezbollah and other proxies around the region.

This encircling “ring of fire” from Lebanon and elsewhere could overwhelm Israel’s multi-layered air defenses with barrages larger than anything yet seen. To be sure, Iron Dome held its own in recent Gaza conflicts. It did so even as the rate of incoming fire increased from 200 rockets daily in 2014 to as many as 400-500 per day in 2021, including 130-rocket barrages, and even as fully half of the recent rocket launches threatened populated areas (up from 20 percent in 2014).

But Hezbollah will launch as many as 3,000 rockets, missiles and drones daily at the outset of the next war – nearly as many as in the entire 2006 and 2014 wars – and at a sustained rate of around 1,000 per day, threatening to oversaturate not just Iron Dome but Israel’s other air defenses as well.

And finally, Hezbollah gained valuable battlefield experience since its last war with Israel. It learned brutal combined-arms warfare in Syria, including in dense urban cauldrons like Aleppo, and now boasts advanced UAV, air defense, anti-tank, subterranean and other capabilities. Unlike Gaza terrorist groups, whose threats of cross-border incursions were minimal in the last conflict, Hezbollah will deploy these assets not just defensively throughout Lebanon, but also offensively in concerted ground invasions against northern Israel.

TEL AVIV: Following the recent rocket attacks from Gaza, Israeli experts say the IDF needs more versions of ground-to-ground rockets to hit enemy rocket launchers. An Israeli defense source told BD that the use of Israeli ground-to-ground missiles in the recent Nagorno-Karabach war “increased the interest in these missiles, especially the Israel Aerospace Industries (IAI)…

The ensuing conflict will greatly strain Israel’s Defense Forces (IDF) and population. The IDF will have to prioritize countering launchers, suggesting more than 1,000 airstrikes daily in Lebanon, Syria, Gaza and perhaps farther afield, compared to roughly 200 daily in the latest bout of fighting. In all probability, the IDF also would conduct an immediate combined-arms ground operation into Lebanon on a much larger scale than in 2006 or in Gaza in 2014.

With air defenses shielding IDF installations, Israel’s critical infrastructure and cities will depend on passive defense measures and luck. Thousands of rockets and missiles will target industrial, electricity, water and transportation chokepoints, and Israel’s densely-populated coastal heartland. The result could be mass casualties, enormous physical destruction and severe disruptions to basic services.

Though damage to Israel likely will be unprecedented, this conflagration will resemble Gaza and Lebanon conflicts in one key respect. Like Hamas, Hezbollah illegally and intentionally puts civilians in harm’s way, emplacing its extensive military assets near and underneath apartments, schools, mosques and hospitals.

When IDF operations target these sites, Hezbollah will exploit the widespread misunderstanding of the law of armed conflict, disingenuously portraying Lebanese casualties and damage as the result of disproportionate and indiscriminate Israeli firepower – all while Hezbollah launches tens of thousands of unguided rockets indiscriminately at Israeli civilians. Unlike with Gaza, the war’s sheer intensity will undermine continued IDF precautions, like “knock on the roof” and telephone warnings, that exceed the law of armed conflict’s requirements.

Like Hamas, Hezbollah will try to delegitimize Israel because it knows it cannot prevail militarily. As in 2006 and 2014, its adversaries will try to generate political and popular pressure on Israel to terminate legitimate operations prematurely.

Both before, but especially during, this incredibly intense large-scale war, U.S. support for Israel’s freedom of action in legitimate self-defense against shared threats from Iran and its proxies will be more important than ever. This includes ensuring Israel has the necessary tools for its ongoing interdiction campaign against Tehran’s proliferation of precision missiles and other game-changing capabilities to Hezbollah and proxies in Syria, Iraq and elsewhere.

The United States and Israel also must ensure sufficient co-production of Iron Dome systems and interceptors to mitigate Hezbollah’s sheer mass of unguided and short-range rockets and artillery, as well as David’s Sling and Arrow air defense systems to counter Hezbollah’s and Iran’s longer-range and precision arsenals, including drones and ballistic and cruise missiles.

Because this next war will be fought in the court of public opinion as much as the battlefield, American leaders also should proactively educate media and international audiences – including the United Nations – on the law of armed conflict, the IDF’s adherence to it and its willful distortion by Hezbollah, Hamas and U.S. adversaries. This will be crucial to ensure ultimate Israeli success in a major conflict against shared Iranian threats, and to mitigate the appeal and effectiveness of similar strategies against legitimate U.S. military operations in the future.
