Iran's Non-State Actor Network. Hezbollah, Hamas, Houthis, PMF as One System.

The framing of the Iran-sponsored network as a collection of separate groups pursuing separate agendas is what makes it hard to counter. Hezbollah is the Lebanese resistance. Hamas is the Palestinian resistance. The Houthis are the Yemeni resistance. The PMF is the Iraqi Shia militia coalition. Each has its own story, its own history, its own local grievances.

That framing is not wrong. Those local stories are real. But it is incomplete, because the same network that lets each proxy tell its own story also lets Iran run all four as arms of a single coordinated deterrent architecture. The Quds Force pays them, arms them, trains them, and coordinates their operational tempo. Treating them as separate for analytical purposes cedes the analytical ground that Iran has spent forty years shaping.

This is the pillar reference on how the network functions as a system. It covers the structure, the command architecture, the individual arms of the network, the coordination mechanisms, and what the network looks like in the wake of Operation Epic Fury.

The Axis of Resistance as an Operational Concept

The Iranian term is Mehvar-e Moqavemat, the axis of resistance. The concept dates to the early 1980s and the founding of Hezbollah, and it has been articulated most fully by the Supreme Leader in the last two decades. In its Iranian conception, the axis is a distributed regional deterrent architecture designed to raise the cost of hostile action against Iran to a level no adversary is willing to pay.

The architecture is asymmetric by design. Iran cannot match US or Israeli conventional capability directly. It has instead spent forty years building a network that lets it impose costs on adversaries in locations Iran does not have to defend, using forces Iran does not have to acknowledge, on timelines Iran can choose. That is a strategy of deterrence via distribution.

What the Axis Actually Does

The axis holds Israel at risk from the north through Hezbollah, from the south through Hamas and Palestinian Islamic Jihad, and from the southeast through the Houthis. It holds US forces in Iraq at risk through PMF and Kataib Hezbollah. It holds US forces in Syria at risk through Fatimiyoun and Zainabiyoun brigades. It holds Gulf states at risk through the Houthi cruise missile and drone inventory, plus deniable operations against energy infrastructure.

Every one of those pressure points is a distributed piece of Iranian deterrence. Every one can be activated independently. Every one carries an implicit threat of the full activation, which is what actually keeps the pressure on.

The Command Architecture

The formal command line runs through the Islamic Revolutionary Guard Corps and specifically the Quds Force, the external operations arm. The Quds Force reports directly to the Supreme Leader, bypassing the Iranian President and the Foreign Ministry. That is deliberate architecture. The Supreme Leader retains personal control over the axis, and the axis is not subject to civilian oversight or diplomatic constraint from other Iranian institutions.

The Quds Force Role

The Quds Force performs four functions across the network. It funds the proxies, either directly or through laundered channels. It arms them, primarily with Iranian-produced systems including drones, cruise missiles, and precision-guided munitions. It trains them, both at Iranian facilities and through in-theater advisors. It coordinates operations across theaters when Iran wants coordinated response.

The Quds Force is not the operational command of the proxies. The proxies retain autonomous command of their own operations. The Quds Force provides the strategic direction and the material capability, then lets local commanders decide operational tempo. That distributed model is what gives Iran plausible deniability while preserving strategic control.

The Soleimani Legacy

Qassem Soleimani built most of the current architecture during his 22 years as Quds Force commander. His personal relationships with Hezbollah, Hamas, PMF, and Houthi leadership were the connective tissue that made the network function. His January 2020 killing was expected in some Western analysis to disrupt the network permanently. In practice, the network survived because Soleimani had institutionalized the relationships and built successors specifically to preserve continuity.

His successor, Esmail Qaani, has run the Quds Force with less personal charisma and less operational visibility. The network has continued to function. The lesson is that individual leadership decapitation, even at the most senior level, does not by itself break a network with institutional depth.

The Four Arms

Hezbollah as the Anchor

Hezbollah is the network's oldest, most sophisticated, and most capable arm. Founded in Lebanon in 1982 with direct IRGC support, Hezbollah has evolved into a hybrid political-military organization that functions as a state within the Lebanese state. It has its own parliament bloc, its own social welfare system, its own communications network, and a military capability that outclasses the Lebanese Armed Forces on most metrics.

Hezbollah's military capability is anchored in a rocket and missile arsenal estimated at over 150,000 systems ranging from short-range Katyusha-style artillery rockets through precision-guided munitions with 300-kilometer range. The arsenal is dispersed throughout southern Lebanon, embedded in civilian infrastructure by design, and layered to survive Israeli strike campaigns.

The 2006 Lebanon War established Hezbollah's operational credibility. The current force posture is measurably more capable than the 2006 force, with precision-guided munitions, an air defense capability, an anti-ship missile inventory, and increased command-and-control sophistication. Israeli planning for a Hezbollah scenario is the most demanding conventional planning problem in Israel's threat portfolio.

Hamas as the Deniable Arm

Hamas relationship to Iran is more complicated than the Hezbollah case. Hamas is Sunni. Its ideological roots are in the Muslim Brotherhood, not Shia Islamism. It has periodically distanced itself from Iran over the Syrian civil war and other issues. Nonetheless, Iranian material support to Hamas has been continuous since the 2000s, and Hamas military capability has grown substantially through that support.

The October 7, 2023 attack demonstrated a capability level that surprised most Western analysis. The operational sophistication of the assault, the coordination between ground infiltration and rocket suppression, and the exploitation of Israeli intelligence gaps were consistent with training and doctrine derived from IRGC and Hezbollah models. Whether Iran had operational foreknowledge of the specific operation remains disputed. That Iran built the underlying capability is not disputed.

The Houthis as the Disruptive Arm

The Ansar Allah movement, commonly called the Houthis, took control of Sanaa in 2014 and has held it against a Saudi-led coalition intervention. Iranian support to the Houthis expanded dramatically after the intervention began. The Houthi missile and drone inventory now includes Iranian-derived cruise missiles capable of reaching Riyadh and Abu Dhabi, plus a maritime capability that threatens Red Sea and Bab el-Mandeb shipping.

Houthi strikes on Aramco facilities in September 2019, on Emirati targets throughout 2022, and on Red Sea shipping in 2023 and 2024 demonstrated that the disruptive capability is real and can be activated on Iranian timelines. The Houthi arm is the least controlled from Tehran because Houthi leadership retains ideological and operational autonomy, but it is also the most useful to Iran because the geographic distance provides deniability.

The PMF as the State-Adjacent Arm

The Popular Mobilization Forces, in Arabic Al-Hashd Al-Shaabi, is the coalition of primarily Shia militias that mobilized in 2014 to fight ISIS in Iraq. The PMF was formally integrated into the Iraqi state security architecture in 2016 but retains substantial autonomy, and the most powerful factions within it, including Kataib Hezbollah, Asaib Ahl al-Haq, and Harakat Hezbollah al-Nujaba, maintain close operational and financial ties to Iran.

The PMF's strategic value is that it operates inside the Iraqi state, making direct strikes against it politically complicated. It has been used repeatedly to harass US forces at Ain al-Asad and other bases, to conduct rocket fire on Green Zone in Baghdad, and to serve as a deniable escalation option that Iran can adjust without acknowledging.

Coordination Mechanisms

The network coordinates through three primary channels.

The Money Channel

Iranian financial support to the proxies has been estimated in the hundreds of millions of dollars annually for Hezbollah alone, with lesser but still substantial figures for the others. The money moves through hawala networks, front companies, sanctions-evading banks, and cryptocurrency in more recent years. The financial architecture has adapted continuously to sanctions and interdiction pressure. It has not been meaningfully disrupted despite decades of Treasury Department targeting.

The Weapons Channel

Iranian arms transfers to the proxies flow through several documented routes. To Hezbollah, historically through Syria and now through complicated overland and maritime routes given the post-Assad Syrian collapse. To the Houthis, through Iranian maritime shipments interdicted repeatedly by US and coalition navies but continuing at scale. To PMF, through direct overland transfer from Iranian territory. To Hamas, historically through the Sinai and Red Sea, with severe disruption after the 2023 conflict.

The pattern is that no single interdiction campaign has stopped weapons flows. The pattern reduces flows and imposes costs but the flows resume through adapted routes.

The Personnel Channel

Iranian trainers, advisors, and Quds Force personnel operate throughout the theaters. Hezbollah has hosted Iranian personnel continuously since the 1980s. The PMF trains at Iranian facilities inside Iran. Houthi personnel train in Iran and Lebanon. The personnel channel is what transmits doctrine and tactics across the network, which is why the operational patterns are so similar across the four arms.

What Coordination Looks Like in Practice

Coordinated network activation has happened multiple times in recent years. The pattern is consistent enough to be readable.

The Ring of Fire Concept

The Iranian articulated concept of a Ring of Fire around Israel involves simultaneous pressure from Hezbollah in the north, Hamas and PIJ in Gaza, occasionally the West Bank, and Houthi missile fire from Yemen. Coordinated activation of even two of those fronts imposes significant operational cost on Israel because it forces multi-front air defense operations, multi-front intelligence collection, and multi-front strike planning.

The Ring of Fire is not a doctrine that Iran has fully activated. Full activation has been threatened repeatedly but held in reserve, which is the actual deterrent posture. The threat of full activation is more useful to Iran than the reality of full activation, because the threat costs Israel resources continuously while the reality would cost Iran the network.

The Iraq Pressure Cycle

Iranian pressure on US forces in Iraq has cycled up and down repeatedly with escalation dynamics elsewhere. When Iran wants to demonstrate options without direct action, PMF rocket fire on Ain al-Asad increases. When Iran wants to signal de-escalation, that fire decreases. The signal is legible enough that US analysts read it continuously.

The Yemen-Red Sea Dimension

Houthi attacks on shipping in the Bab el-Mandeb during the current cycle demonstrated the network's ability to open new fronts at will. The attacks imposed real economic cost, disrupted global shipping, and required a US-led coalition maritime response. From the Iranian point of view, the Houthi front was a proof of concept for how the network can create pressure on Israeli and US positions that no direct Iranian action could achieve.

What Epic Fury Changed

Operation Epic Fury, the sustained strike campaign against Iranian nuclear and IRGC infrastructure in 2026, hit the network at its core rather than at its arms. That distinction matters.

Direct strikes on the Quds Force facilities, on Iranian arms production, and on the IRGC Aerospace Force degraded the resource base that supplies the proxies. It did not destroy the proxies themselves, which are geographically distributed and largely independent of any single Iranian facility. It did degrade the sustainment pipeline that keeps the proxies armed and functional over time.

The observed result in the months following Epic Fury has been a partial reduction in proxy operational tempo, particularly in the higher-end missile and drone strikes that depend on Iranian resupply. Local operations have continued at near-baseline levels. The larger-scale coordinated operations have decreased.

Whether that degradation is durable or whether Iran rebuilds capability through parallel channels is the question every subsequent brief tracks.

What Breaks the Network

Historical analysis of what has and has not disrupted the network gives a clear pattern.

What has not worked: Targeted killings of network leadership. Sanctions on individual commanders. Interdiction of individual weapons shipments. Direct strikes on proxy facilities. Each of these has imposed cost, but the network has adapted around each.

What has partially worked: Sustained pressure on the Iranian sustainment pipeline. Combined military and economic pressure. Coalition activity that shrinks the sanctuary space in which the proxies operate.

What might work: Regime change in Iran itself, or a Syrian-style collapse of one of the axis states in a way that Iran cannot substitute for. Neither has happened at scale. Neither is cheap.

Reading the Network Week to Week

Every MERIDIAN Iran brief that touches proxy activity reads the network as a system. Which arms are active. Which arms are quiet. Where the coordination signals are appearing. What the Quds Force is signaling through operational tempo rather than through statements. That systemic reading is the analytical value the briefs try to deliver.
