The Lebanonization of Iran

In November 2024, after thirteen months of a war which broke Hezbollah's senior command, pulverised its missile stocks, and put Hassan Nasrallah in a grave he did not choose, a US-French ceasefire routed the enforcement of disarmament through the Lebanese state. The Lebanese Armed Forces - the national army, which is to say the army that is not Hezbollah - put ten thousand troops into the south. Washington committed $192.7 million in support to the LAF and a further $45 million to the Internal Security Forces, on the explicit understanding that further tranches would flow in proportion to disarmament. The Secretary of Defence and CENTCOM were instructed to file with Congress, by 30 June 2026, on the LAF's progress. The instruction had a date on it, which is the trade's way of saying that someone was going to be held accountable for the answer.

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, Salam, was saying in public that the first phase was close to complete. Hezbollah's stated line, for the cameras, was that it would not fully disarm until the Israelis withdrew from the five points still held inside southern Lebanon. The mechanism, however, ran around that insistence: the LAF kept operating, the aid kept disbursing, the weapons kept coming out of the ground. As ever in these matters, the public position and the operational position were on different schedules.

The shape of it is what one wants to fix in mind. External force does the degrading; an army inside the same country, newly funded and newly legitimate, does the rest. Western money is channelled exclusively through the state military, on conditions tied to the paramilitary's constraint. Lebanon disarms Hezbollah; the Israelis pay the difference in air power when the Lebanese pace is too slow. It is, for what is in essence a colonial problem dressed up as a security one, the cheapest strategy on the menu - and it is the template against which the next eighteen months of Iran policy will be judged, whether the men running the policy admit so or not.

Iran has two armies, and they do not love each other. Most Western commentary, including a great deal that should know better, collapses them into a single "Iranian military" which is then identified with the IRGC - an act of analytical convenience that flattens a distinction the regime 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 - and around four hundred and twenty thousand active personnel. Conventional doctrine, organised around border defence and inter-state warfare. The senior officers of the present generation were trained, in their formative years, by men whose own training came from American and British programmes of the 1960s and 1970s; the revolutionary government purged most of that first generation, but the institutional culture - the professional, non-revolutionary, regular-soldier culture - survived the purge. The Artesh's charter is the external defence of Iran, not the internal enforcement of revolution. That distinction was written into the constitution from the start.

The IRGC was created in 1979 to be the army the revolution kept against Iranians. Khomeini did not trust the Artesh; the generals had been selected for loyalty to a Shah who was now in exile, the equipment was American, the doctrine was a foreigner's doctrine. So a parallel revolutionary force was stood up alongside it. Five branches - ground, navy, aerospace (which is to say the missile and drone programmes), the Quds Force (external operations and proxy management), and the Basij (paramilitary, neighbourhood-level, ideological). Asymmetric doctrine, a parallel chain of command reporting to the Supreme Leader and to no one else, and, over forty-six years of patient institutional capture, an estimated half of Iran's gross domestic product flowing through entities the Guard owns or controls.

The two have been rivals from the start. The rivalry is structural - the constitution assigns overlapping responsibilities, and the regime has cultivated the rivalry on purpose, because a single unified force would have had a leverage neither Khomeini nor his successor wanted to allow. The Guard takes the larger budget despite being the smaller force; the Artesh takes the conventional-defence mission, which confers legitimacy but no political weight. The trade phrase for it is Eternal Rivals, and the rivalry is older than most Iranian voters.

The present war has made the rivalry louder, and someone - the trade is left to surmise who - has been acting on the distinction. Mohammad Pakpour, Ground Forces of the IRGC: killed Day One. Alireza Tangsiri, IRGC Navy: killed 27 March. Behnam Rezaei, IRGC Naval Intelligence: same day. Majid Khademi, IRGC Intelligence chief and effectively the Guard's number two: killed 6 April. Asghar Bagheri, Quds Force special operations: killed in the same strike. Ali Shamkhani, Defence Council: killed Day One. Every senior figure on the published kill list is Guard or Guard-adjacent; not one is Artesh command. The Artesh chief of staff is alive. So are the commanders of its four branches. Over eight weeks of what Western reporting was content to call a comprehensive decapitation campaign, one of Iran's two armies has had its command systematically beheaded, and the other has not. If the aim were to destroy the Iranian state, the gap is hard to explain. Under the Lebanon template, it explains itself: the army you intend, after the deal, to channel aid through is not an army whose officers you kill in advance.

What the campaign did not spare was the Artesh's hardware. The IRIN - the Artesh Navy - is in essence finished: the Moudge-class frigate IRIS Dena was torpedoed and sunk by an American submarine in the Indian Ocean, more than a hundred naval vessels have been written off, and Mr Trump has stood at a microphone and announced that the Iranian navy and air force have been destroyed. The Air Force and the air defences went the same way. What the kill list spared was the institutional carrier - the staff structure, the officer corps, the chain of command. The hulls and the airframes are a different question, and the answer to that question is the question a deal exists to answer.

A reconciliation, before going further. This War Destroys Everything Except the IRGC argued that the Guard is consolidating domestic power as the pragmatists, mediators, and moderates around it are killed off. The reading holds, and it composes with this one. R005 was tracking a domestic-political axis: the clerical, civilian, and diplomatic functions the Guard absorbs as their holders are eliminated. The Artesh is not on that axis. It is the professional military, neither a reformist faction nor a competitor for commercial turf, and the assassination campaign that hollowed out the civilian-political field had no occasion to touch it. A deal opens a different axis altogether: external legitimacy, foreign aid, and the military-to-military relationships the Guard cannot credibly occupy. The Guard goes on 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 the small print, is turn money and recognition back on. Foreign investment returns. Frozen assets are unfrozen. Western firms, hesitant at first, send their advance parties; Gulf capital starts routing through Iranian banks again, having declined to do so for a decade.

Very little of that capital enters through the IRGC. Foreign investors, Western banks, Gulf sovereign funds - none of them will touch the commercial Guard directly. The ownership structures are opaque, the sanctions exposure is a career-ending matter for the compliance officers who would have to sign off, 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 Guard's commercial arm will of course capture a share downstream, given how much of the economy it touches; but the point of entry, the institutional relationships, and the architecture of compliance that comes with them all sit on the civilian side.

Military aid is the rarer item on the menu, and the more consequential one. The Americans arm the Egyptian, Jordanian, and now Lebanese militaries - state forces, never revolutionary paramilitaries, this distinction having been observed in Washington for three quarters of a century with very few exceptions. An Artesh positioned as a partner in regional stability gets the same menu: staff-college exchanges, mine-clearance cooperation in the Gulf, counter-narcotics work along the Afghan frontier. None of it large in itself. Compounded over five to ten years, what it gives the Artesh officer corps is precisely the external peer relationships the Guard has spent forty-six years suppressing. The LAF is the standing demonstration of where that road leads.

And none of it has to be framed as arming one Iranian army against the other. A normalising state requires a normalising military. The framing is in the dictionary; one need only look it up.

Capacity transfer is slow. Confrontation is not - it arrives at specific moments at which doing the Artesh's lawful job means acting against the Guard. Two near-term triggers, in order of likelihood.

Nuclear inspection. Any deal that restores IAEA access to declared facilities will require someone, in the end, to walk to the gate and unlock it. The facilities are Guard-controlled. The inspectors arrive through civilian-government channels, under the seal of the foreign ministry. The enforcement force available to compel Guard compliance, should the Guard decline, is an Artesh unit - because no other Iranian institution can do it without precipitating exactly the civil conflict the regime has spent forty-six years engineering itself against. Civilian-government orders, in the name of a treaty signed in Geneva or Vienna, end with Iranian soldiers standing outside an Iranian nuclear facility guarded by other Iranian soldiers. That is the trigger.

Proxy constraint. The deal will contain language, in some form, on Iran's support for Hezbollah, the Houthis, and the Iraqi militias. Interdicting the shipments the Quds Force runs is work that falls to the Artesh, or to coordinated Artesh-civilian intelligence, because the Guard cannot be asked to police itself. Each interdiction weakens the proxy network the Guard has spent four decades building, and strengthens the Artesh in its position as enforcer of the state's treaty obligations. The pattern, once it begins, runs on its own.

Hormuz completes 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, the hulls required for escorting having been sent to the bottom during the war. The 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 aside, the third trigger has arrived.

None of these triggers requires the Artesh to want to confront the Guard. They require the Artesh to do its lawful, ordinary, professional job in circumstances under which doing that job means acting against the Guard. The LAF did not want to fight Hezbollah either. It had only to enter the villages Hezbollah had been operating in, take possession of the weapons Hezbollah had been storing there, and escalate at each instance of resistance. Eighteen months in, phase one is close to complete.

Five reasons, in the trade's spirit of holding theses loosely.

Artesh capacity. The Artesh is, at present, institutionally weaker than the LAF was at the equivalent stage of its arc. The war has put its conventional hardware off the board; the navy, the air force, and the air defences are largely gone, and the officer corps is now waiting on materiel that has to be rebuilt before it can be deployed. Decades of underfunding and political demoralisation do not reverse in months. The LAF was built up over fifteen years before the 2024 campaign made its disarmament role possible; Iran has not got fifteen years - the early triggers will arrive long before the capacity does, if the capacity ever reaches the scale the mechanism requires. Lebanon itself, for that matter, is not yet a settled case. Phase one at eighteen months is a stage, not an outcome.

Command unity from the top. Mojtaba Khamenei, who succeeded his father, formally commands both forces. He owes his office to the Guard, and he holds appointment authority over both chains of command. If he keeps the Artesh subordinated to Guard primacy, the mechanism does not start. There are signs his health and his political capital are both less than the Guard would prefer them to be; but signs are signs, and not yet a fact pattern.

The Basij offset. The Basij is the Guard's domestic counterweight. Should the Artesh begin to assert itself in the cities, the Basij's neighbourhood network is the force that materialises at Artesh barracks gates with crowds in tow. Professional conventional infantry does not engage paramilitary mobs lightly; the political cost is high enough to stop the engagement before it begins. The trade has seen this calculation made in other places, and it is rarely won by the regulars.

Kill list over-read. The Guard ran this war - the missiles, the proxies, the nuclear file, the public face of escalation. The Artesh had no operational role in it. A campaign that targets the force actually running the war will look identical, in its outputs, whether or not anyone in Tel Aviv or Washington was thinking about what comes after. The pattern admits an innocent reading.

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, in the trade's experience, gets exercised.

Specific indicators, over the six months following a signed agreement.

Confirming. An American security-assistance package that names the Artesh by institution as recipient. Any Artesh deployment to a Persian Gulf escort role. Defence cooperation announcements between a Gulf state and the Iranian civilian government in which the Guard is conspicuously not a party.

Refuting. Sanctions relief structured such that Guard-linked commercial entities capture the dividend. Mojtaba restructuring military command to unify the services under Guard primacy. Public statements from Artesh commanders deferring to Guard authority on the matters set out above.

Telling either way. A Gulf state - the obvious candidate is Saudi Arabia - publicly proposing cooperation with the Iranian civilian government on Gulf security, and naming the channel.

The war between states ends with a signature. What begins after it is a slower, quieter war - the war that runs through budget allocations, training programmes, and the question of which Iranian army answers the telephone when the civilian government in Tehran picks it up. Lebanon has been running this war for eighteen months, and the first phase has gone well enough that the United States Congress has put the next progress report on its calendar for the summer.

The pieces are in place. The kill list has systematically degraded one of Iran's two armies and largely spared the other. The deal under negotiation will, in the practical course of things, route resources to the army left intact. The rivalry between the two is older and deeper than any individual Iranian leader, and the Americans hold a working template for converting precisely this configuration into a sustained disarmament process.

This may be Israel's strategy, or an alignment that Israel will come to exploit, or a pattern that does not survive contact with whatever document is ultimately signed. But if a reader closes this tab, and over the year that follows watches American military aid begin to flow to an Iranian force called the Artesh, and sees headlines about Artesh-IRGC clashes at nuclear sites or over interdicted proxy shipments - this is what it was going to look like. The Israelis do not need to destroy the Guard. They need an Iranian army willing to try, and a deal that gives that army the money and the legitimacy to make the attempt.

They have spent eight weeks killing the men who could have stopped it. The deal is what the kill list was for.
