What this actor is
Iran enters the Levant system as the principal external supporter of Hezbollah and, according to US government reporting, of Palestinian Islamic Jihad and Hamas. Its war with Israel and the United States is the Iran–Gulf module's record; what this record holds is how Iranian support reaches Lebanon and the Palestinian territories, and how that changed. The fall of the Assad government in December 2024 and Lebanon's ban on Iranian flights from February 2025 closed the land and air routes, after which funding was rerouted through Türkiye, Iraq, the sea and exchange houses, and more than $1bn reached Hezbollah after the November 2024 ceasefire, according to a UN report. The war also connected the fronts formally: the US–Iran memorandum announced on 14 June 2026 stipulated a cessation of hostilities on the Lebanese front, according to the UN. No primary evidence of Iranian funding routes to Hamas or PIJ after 2025 was found.

What this record covers
Iran's direct war with Israel and the United States, and its effects in the Gulf, are the Iran–Gulf module's; Iranian movement through Syria is the Syria module's. This record follows only what arrives — money, materiel and political cover — in Lebanon and the Palestinian territories, and the points at which Iranian decisions formally bind a Levant front, as the June 2026 memorandum, since lapsed, did for Lebanon.
Constraints
The routes that made Hezbollah's supply cheap no longer exist in their old form. Damascus is no longer a partner, Beirut's airport is closed to Iranian flights, and the Lebanese government has banned Hezbollah's military activity. Syria's interior ministry said in July 2026 that it seized Hezbollah-bound weapons at the Iraqi border, which Hezbollah denies — a claim the Syria module owns.

Position in the system
Iran is the patron whose support every Lebanon instrument aims to replace with the Lebanese state's monopoly of arms, and whose own war with Israel set the 2026 Levant fronts in motion. Its influence on Gaza is not established from evidence read for this module.

Objectives
What the actor says, kept apart from what Vigil assesses. Each stated entry cites where the position was made; Vigil records that it was made, not that it is true.
Stated by the actor
A cessation of hostilities on the Lebanese front as part of the US–Iran memorandum announced on 14 June 2026, as recorded by the UN.

Assessed by Vigil
Preserving Hezbollah as a capability rather than as a front: Iran's continued funding after the 2024 ceasefire, at a time when the land route had closed, points to an aim of keeping the organisation intact while its armed role in Lebanon is contested.
Confidence: Low Sources: UN Security Council resolutions, Secretary-General reports and meeting records (Levant)↗ · Washington Institute for Near East Policy↗
Linking the Lebanese front to its own negotiations with the United States, so that a cessation in Lebanon is something Iran helps deliver rather than something imposed on its partner without it.

Constraints
What limits this actor's options, with the kind of limit it is.
Loss of the Syrian land route after December 2024 and of air access to Beirut from February 2025.
External Confidence: Moderate Sources: UN Security Council resolutions, Secretary-General reports and meeting records (Levant)↗
The Lebanese state's 2 March 2026 ban on Hezbollah's military activity and its undertaking in the Trilateral Framework to block funds to non-state armed groups.
External Confidence: Moderate Sources: Lebanese government statements and decisions (Presidency, Council of Ministers, ministries)↗ · Treaty and agreement texts — Israel, Palestine, Lebanon and neighbours↗
Its own war with Israel and the United States — Iran–Gulf's record — which absorbs the resources and command attention support for the Levant depends on.

Sources of leverage
What this actor can bring to bear, and how firmly each is established.
