The Lebanonization of Iran

In November 2024, after thirteen months of war that broke Hezbollah's senior command, pulverised its missile stocks, and killed Hassan Nasrallah, a US-French ceasefire routed all enforcement through the Lebanese state. The Lebanese Armed Forces - the national military that is not Hezbollah - deployed ten thousand troops into the south. The United States committed $192.7 million to LAF support, plus $45 million to the Internal Security Forces, with the explicit condition that further aid would flow in proportion to disarmament progress. The US Secretary of Defence and CENTCOM were directed to report to Congress by June 30, 2026, on the LAF's progress.

Within ten months the LAF had physically removed an estimated ten thousand rockets and four hundred missiles from Hezbollah stockpiles. By December 2025 the Lebanese prime minister was announcing that the first phase of disarmament was close to complete. Hezbollah's public line was that it would not fully disarm until Israel withdrew from five points still held inside southern Lebanon - but the mechanism ran around that insistence. The LAF kept operating, the aid kept disbursing, and the weapons kept coming out of the ground.

The shape of the template matters. External force does the degradation; a state military inside the same country, newly funded and newly legitimate, does the rest. Western aid is channelled exclusively through the state military, on conditions tied to the paramilitary's constraint. Lebanon disarms Hezbollah; Israel pays the difference in air power when the Lebanese pace is too slow. It is the cheapest strategy for constraining an armed non-state actor whose host country cannot be occupied, and it is the template the next eighteen months of Iran policy will be measured against.

Iran has two militaries, and they dislike each other. Most Western discussion collapses them into a single "Iranian military" identified with the IRGC, flattening a distinction the Iranian state has spent forty-six years maintaining on purpose.

The Artesh is the regular armed forces, inherited institutionally from the Shah. Four branches - ground, navy, air force, air defence - around 420,000 active personnel. Classical conventional doctrine, structured around border defence and inter-state warfare. The senior officer corps trained under American and British programmes in the 1960s and 1970s, and although the revolutionary government purged most of that generation, the institutional culture of professional non-revolutionary service survived. The Artesh's charter is external defence of Iran, not internal revolutionary enforcement - that was built into the distinction from the start.

The IRGC was created in 1979 to be the army the revolution relied on to defend itself against Iranians. Khomeini did not trust the Artesh - the generals had been selected for loyalty to the Shah, the equipment was American, the doctrine was foreign - so a parallel revolutionary force was stood up alongside it. Five branches - ground, navy, aerospace (missiles and drones), the Quds Force (external operations and proxy coordination), and the Basij (paramilitary, neighbourhood-level, ideological enforcement). Asymmetric doctrine, a parallel chain of command reporting directly to the Supreme Leader, and, over forty-six years, an estimated half of Iran's GDP under IRGC-linked commercial entities.

The two have been rivals from the start. The rivalry is structural - the constitution assigns overlapping responsibilities, and the regime kept it alive on purpose, because a single unified force would have had leverage neither Khomeini nor Khamenei wanted it to have. The IRGC gets a bigger budget despite being smaller; the Artesh gets the conventional-defence mission that confers legitimacy but not political power. Eternal Rivals is the phrase the analytical literature uses, and the rivalry is older than most Iranian voters.

This war has made the rivalry louder, and the kill list suggests someone is already acting on the distinction. Mohammad Pakpour - IRGC Ground Forces, killed Day One. Alireza Tangsiri - IRGC Navy, killed March 27. Behnam Rezaei - IRGC Naval Intelligence, same day. Majid Khademi - IRGC Intelligence chief, effectively the Guard's #2, killed April 6. Asghar Bagheri - Quds Force special operations, same strike. Ali Shamkhani - Defence Council, killed Day One. Every senior command figure on the list is IRGC or IRGC-adjacent; none is Artesh command. The Artesh chief of staff is alive, as are the commanders of its four branches. Over eight weeks of what Western reporting called a comprehensive decapitation campaign, one of Iran's two militaries has had its command systematically beheaded and the other's command left intact. If the campaign aim were destroying the Iranian state, the gap is hard to explain. Under the Lebanon template it explains itself: the force you are going to channel aid through after the deal does not get its officers killed beforehand.

What was not spared is the Artesh's conventional hardware. The IRIN - the Artesh Navy - has been all but destroyed during the war: the Moudge-class frigate IRIS Dena was torpedoed and sunk by a US submarine in the Indian Ocean, over a hundred naval vessels have been written off, and President Trump has publicly declared the Iranian navy and air force destroyed. The Air Force and air defences went with them. What the kill list spared was the institutional carrier - the officer corps, the staff structure, the chain of command. The hulls and the airframes are another question, and the answer to that question is what a deal is for.

A reconciliation first. This War Destroys Everything Except the IRGC argued the IRGC is consolidating domestic power as the pragmatists, mediators, and moderates around it are killed. That reading holds, and it composes with this one. R005 tracked a domestic-political axis - the clerical, civilian, and diplomatic functions the IRGC absorbs when their holders are eliminated. The Artesh is not on that axis. It is the professional military, neither a reformist faction nor a competitor for economic turf, and the assassination campaign that hollowed out the civilian-political field had no reason to touch it. A deal opens a different axis entirely: external legitimacy, foreign aid, and military-to-military channels the IRGC cannot credibly occupy. The IRGC keeps absorbing every dead moderate's portfolio. That does not stop the Artesh from growing through the doors a deal opens.

What a deal does, regardless of its specific terms, is turn money and recognition back on. Foreign investment returns, frozen assets unfreeze, Western companies test the waters, and Gulf capital starts routing through Iranian banks again.

Very little of that enters through the IRGC. Foreign investors, Western banks, and Gulf sovereign funds refuse to touch the commercial Guard directly - ownership structures are opaque, sanctions exposure is a career risk, and forty years of making the institution radioactive have done their work. Money flowing back into Iran after a deal enters through the Central Bank, the ministries, the civilian economy. The commercial Guard will still capture a share downstream given how much of the economy it touches - but the point of entry, the institutional relationships, and the compliance architecture that comes attached all sit on the civilian side.

Military aid is the rarer case but the more consequential one. The United States arms the Egyptian, Jordanian, and now Lebanese militaries - state forces, never revolutionary paramilitaries. An Artesh positioned as a partner in regional stability gets the same menu: staff-college exchanges, mine-clearance cooperation in the Gulf, counter-narcotics programmes on the Afghan border. Each is small on its own. Cumulatively, over five to ten years, they give the Artesh officer corps exactly the external peer relationships the IRGC has suppressed for forty-six years. That is how the LAF got where it is.

And none of it has to be framed as arming one side against the other. A normalising state needs a normalising military.

Capacity transfer is slow. Confrontation is not - it arrives at specific moments when doing the Artesh's normal job means acting against the IRGC. Two plausible near-term triggers, ordered by likelihood:

Nuclear inspection. Any deal that restores IAEA access to declared facilities requires someone to physically open the gates. The facilities are IRGC-controlled, the inspectors arrive through civilian-government channels, and the enforcement force available to compel IRGC compliance - if the IRGC refuses - is an Artesh unit. Civilian-government orders, in the name of a treaty, put Iranian soldiers outside an Iranian nuclear facility guarded by other Iranian soldiers.

Proxy constraint. The deal will contain language about Iran's support for Hezbollah, the Houthis, and Iraqi militias. Interdicting the shipments the Quds Force organises falls to the Artesh or to coordinated Artesh-civilian intelligence operations. Each interdiction weakens the IRGC's proxy network - built over four decades - and strengthens the Artesh's position as enforcer of the state.

Hormuz would complete the set - freedom-of-navigation language in any deal puts escort duty with the Artesh Navy by doctrine. That trigger is on a longer clock than the other two, because the hulls to do the escorting were sunk during the war. A deal's capacity-transfer flow is what rebuilds them; when the first rebuilt Artesh frigate deploys to the Strait and the IRGC Navy has to be told to stand down, the third trigger arrives.

None of these triggers require the Artesh to want to confront the IRGC. They require the Artesh to do its normal legitimate job in circumstances where doing that job means acting against the IRGC. The LAF did not want to fight Hezbollah either. It only had to move into villages Hezbollah had been operating in, confiscate weapons Hezbollah had been storing, and escalate each time Hezbollah pushed back. Eighteen months in, the first phase is close to complete.

Five reasons to hold this reading loosely.

Artesh capacity. The Artesh is institutionally weaker than the LAF was at the equivalent stage, and the war has taken its conventional hardware off the board - the Navy, Air Force, and air defences are largely gone, so the officer corps now waits on materiel that has to be rebuilt before it can be used. Decades of underfunding and demoralisation do not reverse in months either. The LAF was built up for fifteen years before the 2024 campaign made its disarmament role possible, and Iran does not have fifteen years - the early triggers will arrive before the capacity does, if it ever reaches the scale the mechanism requires. Nor is Lebanon itself a settled case; phase one at 18 months is a stage rather than an outcome.

Command unity from the top. The Supreme Leader, Mojtaba Khamenei, who succeeded his father, formally commands both forces. He owes his office to the IRGC and has appointment authority over both chains of command. If he keeps the Artesh subordinated to IRGC primacy, the mechanism does not start.

The Basij offset. The Basij is the IRGC's domestic counterweight. If the Artesh asserts itself domestically, the Basij's neighbourhood network is the force that shows up at Artesh barracks with crowds. Professional conventional infantry does not engage paramilitary mobs lightly; the political cost is high enough to stop it.

Kill list over-read. The IRGC ran this war - the missiles, the proxies, the nuclear file. The Artesh had no operational role. A campaign that targets the force actually running the war will look identical whether or not anyone is thinking about what comes after.

No Israeli strategy at all. The Israeli-strategic-intent reading may simply be wrong. Israel may be stumbling into the configuration rather than building toward it. The narrower thesis survives either way: the configuration is in place, it enables the strategy, and it costs Israel nothing if the strategy turns out to be something else. A free option usually gets exercised.

Specific indicators over the six months after a signed deal:

Confirming. A US security assistance package that names the Artesh as recipient. Any Artesh deployment to a Persian Gulf escort role. Gulf-state defence cooperation announced with the Iranian civilian government.

Refuting. Sanctions relief structured so IRGC-linked commercial entities capture the dividend. Mojtaba restructuring military command to unify the services under IRGC primacy. Public Artesh statements deferring to IRGC authority.

Telling either way. A Gulf state - Saudi Arabia is the obvious candidate - publicly offering to cooperate with the Iranian civilian government on Gulf security.

The war between states ends with a signature. What begins after is a slower war that runs through budget allocations, training programmes, and the question of which Iranian army answers the phone when the civilian government calls. Lebanon has been running this war for eighteen months, and the first phase has gone well enough that the United States has scheduled a June 2026 progress report on it.

The pieces are in place. The kill list has systematically degraded one of Iran's two militaries while largely sparing the other. The deal under negotiation will, in practice, route resources to the one left intact. The rivalry between the two militaries is older and deeper than any individual Iranian leader. And the United States has a working template for converting exactly this configuration into a sustained disarmament process.

This may be Israel's strategy, or an accidental alignment Israel will exploit, or an analytical pattern that does not survive contact with whatever gets signed. But if a reader closes this tab and then, over the next year, watches American military aid start flowing to an Iranian force called the Artesh, and reads headlines about Artesh-IRGC clashes at nuclear sites or over proxy shipment interdictions - this was what it was going to look like. Israel does not need to destroy the IRGC. It needs an Iranian army willing to try, and a deal that gives that army the money and the legitimacy to make the attempt.

It has spent eight weeks killing the officers who could have stopped this. The deal is what the kill list was for.
