Hezbollah

Overview

Hezbollah, meaning Party of God, is a Shia political and military organization founded in Lebanon with support from the Islamic Republic of Iran. It operates a political party, social-service institutions, media outlets and an armed force outside the control of Lebanon’s state. Its military campaigns have targeted Israel, while its overseas operations have struck Jewish, Israeli and other targets. The United States designated Hezbollah a foreign terrorist organization in 1997. Its leaders have rejected Israel’s legitimacy and built Hezbollah into a central member of the Iran-aligned Axis of Resistance.

Hezbollah’s position in Lebanese politics does not erase the consequences of its independent arsenal. It has held parliamentary seats and participated in governments while retaining forces capable of initiating a war across Lebanon’s border. Iran has financed, trained and armed the organization, including with rockets and increasingly advanced missiles. The former Syrian government helped sustain its supply routes. These relationships made Hezbollah a principal actor in the wider Iran–Israel proxy conflict and gave Tehran a means to threaten Israeli population centers from Lebanese territory.

Hezbollah’s activities extend beyond fighting Israel. It intervened to preserve Bashar al-Assad’s rule during the Syrian civil war, developed networks abroad and exerted power within Lebanon’s security and political life. Its attacks beginning on October 8, 2023, opened a northern front during the war that followed the October 7 attacks. Israel’s 2024 campaign killed senior commanders, including Hassan Nasrallah, and severely damaged Hezbollah’s forces. The organization nevertheless retained weapons and sought to rebuild, leaving its disarmament a central question for Lebanon.

Founding and ideology

Hezbollah emerged in 1982 amid the Lebanese Civil War, Israel’s war against armed organizations operating from Lebanon and the political mobilization that followed Iran’s 1979 revolution. Members of Lebanon’s Shia community had already organized through the Amal Movement. Militants who favored a more explicitly revolutionary program diverged from Amal and joined other Shia groups under the influence of Iranian advisers. The Islamic Revolutionary Guard Corps sent personnel to Lebanon’s Bekaa Valley to train and organize the emerging movement. Baalbek became an important early center. Hezbollah developed over several years before setting out its political program publicly in 1985.

The movement adopted the Iranian revolution’s model of political Islam and recognized the authority of Iran’s revolutionary leadership. Its program combined Shia religious doctrine, an ambition to shape government and law, and a commitment to Israel’s destruction. This program concerns a specific organization and governing ideology; it does not describe Muslims or Shia believers as a whole. Hezbollah’s stated objectives and its continuing attacks also distinguish its armed campaign from a conventional border dispute between the states of Israel and Lebanon.

Hezbollah built support through religious institutions, schools, health services, charities, youth organizations and its al-Manar television station. These activities gave it influence in communities where state services were weak, but also provided channels for recruitment and political messaging. Educational material and ceremonies documented by the Anti-Defamation League promoted Hezbollah’s fighters and leaders and included antisemitic content. At one school ceremony, Mahdi Scouts played Hezbollah’s anthem beneath its flag while al-Manar was present. Such institutions help explain how the organization maintains a social base alongside its military structure.

History

Hezbollah’s early years were marked by attacks on Western personnel in Beirut. The 1983 bombing of the United States embassy killed 63 people. Later that year, truck bombs struck American and French barracks belonging to the multinational force, killing 241 American service members and 58 French personnel. The attacks made Lebanon a central concern for American and French counterterrorism policy. Iran-backed Hezbollah also held Western hostages during the 1980s; efforts by the Reagan administration to secure Americans’ release became part of the Iran–Contra affair.

Israel withdrew most of its forces from Lebanon in 1985 while retaining a southern security zone. Hezbollah expanded its recruitment and weapons stores and fought Israeli forces and the South Lebanon Army during the South Lebanon conflict. Hassan Nasrallah became secretary-general in 1992 after Israel killed his predecessor, Abbas al-Musawi. Under Nasrallah, Hezbollah entered Lebanon’s parliament, strengthened its military organization and sustained operations against Israel. Israel withdrew from southern Lebanon in 2000 to the internationally identified Blue Line. Hezbollah continued cross-border attacks rather than disarming. Prime Minister Rafic Hariri sought reconstruction and foreign investment, while Nasrallah insisted that Lebanon remain a front against Israel.

In 2004, Nasrallah helped negotiate an exchange in which Israel released hundreds of prisoners for the bodies of three Israeli soldiers and an abducted Israeli businessman. Hezbollah’s capture of Israeli soldiers in July 2006 then triggered the 2006 Lebanon War. It fired rockets into Israeli civilian areas throughout the conflict. United Nations Security Council Resolution 1701 called for an end to hostilities and required the area between the Blue Line and the Litani River to be free of armed personnel and weapons other than those of Lebanon’s government and the United Nations Interim Force in Lebanon, or UNIFIL. Hezbollah retained its arsenal and subsequently expanded it. Before October 2023, Israeli intelligence estimated that it held about 150,000 rockets and missiles, some capable of reaching major Israeli cities.

Hezbollah openly escalated its intervention in Syria in 2013. Its role in the battle of Qusayr showed an organization able to fight along established front lines, hold territory and coordinate with Syrian and Iranian forces. Hezbollah personnel later operated in campaigns near Damascus, Aleppo and Quneitra Governorate, including areas close to Israel’s Golan Heights. This experience expanded its battlefield capabilities, even as the war imposed substantial losses. Iran and Hezbollah helped keep Bashar al-Assad in power for years. After Israel severely weakened Hezbollah in 2024, a rebel offensive ended Assad’s rule, removing a longstanding ally and disrupting Hezbollah’s regional supply network.

Structure and leadership

Hezbollah combines political, military, security, media and social-service structures under a central leadership. Its representatives have served in Lebanon’s parliament and cabinet, while its armed force has retained its own command, weapons and foreign relationships. This arrangement gives Hezbollah substantial influence over national decisions without placing its military operations under the Lebanese Armed Forces. The organization’s ability to store and move weapons in southern Lebanon has repeatedly tested the authority of Lebanese institutions and UNIFIL.

Hassan Nasrallah led Hezbollah from 1992 until Israel killed him in a September 2024 strike on its headquarters. He was the organization’s most prominent public figure and oversaw its political expansion, rocket buildup, intervention in Syria and campaign against Israel. Imad Mughniyeh was a senior figure associated with its external operations until his death in 2008. Fuad Shukr became a senior military commander responsible for advanced weapons, including precision-guided missiles, cruise missiles, anti-ship missiles, long-range rockets and drones. Israel killed him in July 2024. Naim Qassem, a longstanding deputy, subsequently became secretary-general.

Hezbollah’s command also relies on local units and specialized forces. Its Radwan force was developed for offensive operations near Israel’s border, while its missile and drone capabilities allowed attacks across a much wider area. Its participation in Syria gave fighters experience with artillery, armored vehicles and coordination with larger formations. Yet the regional groups described collectively as Iran’s axis do not form a single military command. Hezbollah weighs its own losses, rebuilding needs and the prospect of Israeli retaliation when deciding how to act.

Funding and sponsors

Iran is Hezbollah’s principal external sponsor. The Islamic Republic and its Revolutionary Guard have supplied money, training, weapons and technical assistance since the organization’s formation. Their support helped transform Hezbollah from a collection of militants into a force with extensive rocket stocks and sophisticated missiles. Iran’s Quds Force managed important parts of this relationship. Iranian support has continued through changes in Hezbollah’s leadership; in July 2024, Iranian President Masoud Pezeshkian reaffirmed his government’s backing in a message to Nasrallah.

The former Assad government in Syria served as an ally and a route for Iranian weapons bound for Lebanon. Hezbollah in turn sent fighters to defend Assad during Syria’s civil war. Its access to territory around the Bekaa Valley and routes through Syria strengthened that relationship. Israeli strikes on Iranian and Hezbollah personnel and supply networks sought to obstruct transfers of advanced weapons. Assad’s fall later weakened the land corridor on which Hezbollah had relied.

Hezbollah also raises and moves funds through Lebanese institutions and overseas support networks. Its financial system includes charitable and commercial activities alongside organizations tied to its political and social presence. Investigations have traced illicit procurement, money laundering and other criminal activity associated with Hezbollah networks outside Lebanon. These activities matter because sanctions on Iranian transfers alone cannot account for every means by which the organization sustains personnel and operations. Lebanon’s economic crisis has sharpened debate over the cost of Hezbollah’s arsenal and wars, which have damaged infrastructure, displaced residents and discouraged investment.

Attacks and operations

Hezbollah has attacked Jewish and Israeli targets well beyond Lebanon. Its overseas record includes the 1992 bombing of Israel’s embassy in Buenos Aires and the 1994 AMIA bombing at a Jewish community center in the same city. The AMIA attack killed 85 people. Argentine prosecutors in 2006 accused senior Iranian officials of directing it and Hezbollah of carrying it out; an Argentine appeals court reaffirmed the roles of Iranian officials and Hezbollah operatives in 2024. Hezbollah operatives and cells have also been linked to plots or attacks in Cyprus, Bulgaria, Thailand and other countries. Its 2012 bombing of a bus in Burgas, Bulgaria, killed Israeli tourists and a Bulgarian driver.

Within Lebanon, the 2005 assassination of Rafic Hariri exposed the reach of clandestine networks operating against Hezbollah’s domestic opponents. A United Nations-backed tribunal convicted Hezbollah member Salim Ayyash for his role in the bombing. Prosecutors also presented telephone evidence involving Hezbollah security chief Wafiq Safa and other operatives during preparations for the attack. The tribunal’s findings should be distinguished from a judicial finding that Hezbollah’s leadership ordered the murder. Hariri’s death and subsequent attacks on investigators and anti-Syrian figures deepened Lebanon’s political crisis.

Hezbollah began attacking Israel on October 8, 2023, the day after Hamas’s massacre in southern Israel. Rocket, missile and drone fire continued through the Israel–Hezbollah conflict, killing civilians and soldiers and displacing approximately 68,500 Israelis from northern communities. In June 2024, Nasrallah threatened to draw Cyprus into a wider war if Israel used Cypriot territory or infrastructure. Hezbollah’s attacks also caused fires and damage in northern Israel, including the Golan Heights, part of the State of Israel and the historic region of Bashan, most of which lies in Syria and is today occupied by Syria.

On July 27, 2024, a Hezbollah rocket directed by Shukr struck a soccer field in Majdal Shams in the Golan Heights, killing 12 children and teenagers and injuring 44 others. The Majdal Shams attack became one of the deadliest strikes on Israeli civilians during the northern-front war. On August 21, Hezbollah fired more than 50 rockets in an initial barrage against Katzrin, also in the Golan Heights. Rockets damaged homes, started fires and wounded a resident. Both towns lie in Israel’s Golan Heights within historic Bashan, most of which lies in Syria and is today occupied by Syria.

Israel’s subsequent 2024 Lebanon war struck Hezbollah commanders, launch systems, weapons stores and infrastructure. A ground operation beginning in October exposed missiles, ammunition and combat equipment in southern Lebanese homes, public buildings and agricultural areas. Israeli forces also found a weapons-storage tunnel shaft within sight of a UNIFIL watchtower near Labouna. These discoveries intensified scrutiny of Hezbollah’s entrenchment in the area that Resolution 1701 was intended to keep free of independent armed forces.

Designations and international status

The United States has designated Hezbollah a foreign terrorist organization since October 1997. Other governments have imposed terrorist designations or sanctions, although their legal approaches differ: some have designated the entire organization, while others have distinguished its military component from its political activity. Hezbollah’s parliamentary representation and social-service network have been central to that debate. Neither changes the record of attacks on civilians, hostage-taking and overseas plots associated with its operatives.

International efforts to limit Hezbollah’s military role have centered on Lebanese sovereignty and Resolution 1701. After the 2006 war, the resolution required effective Lebanese state authority in the south and barred unauthorized armed personnel and weapons between the Litani River and the Blue Line. Implementation remained incomplete. A Hezbollah weapons cache exploded south of the Litani in 2009, after which its personnel obstructed access to the site. Local restrictions on UNIFIL patrols persisted in later years. By the 2024 war, UNIFIL had roughly 10,000 troops, yet Hezbollah had built extensive military infrastructure in its area of operations.

Hezbollah’s status also shapes Lebanon’s relations with Israel and other states. The November 2024 Israel–Lebanon ceasefire committed Lebanon’s government to confiscate unauthorized weapons and dismantle Hezbollah’s military infrastructure nationwide. Lebanese President Joseph Aoun subsequently called for arms to be held exclusively by the army and security forces. That position directly challenges Hezbollah’s claim to maintain an independent force. Lebanon’s responsibility to enforce its commitments remains consequential for the security of its own population and Israel’s northern communities.

Current status

Israel’s 2024 campaign killed Nasrallah and other senior commanders, damaged rocket systems and disrupted Hezbollah’s command. The organization nevertheless retained personnel, weapons and political influence. Reports of renewed recruitment, drone production and efforts to restore positions in southern Lebanon showed that military losses had not resolved the underlying question of its arsenal. Israeli operations continued to target Hezbollah operatives and assets involved in rebuilding on both sides of the Litani River, including in January 2026.

Lebanon’s government faces the task of asserting exclusive control over armed force while managing economic damage and competing political interests. Hezbollah’s supporters continue to regard its weapons as a source of influence; opponents argue that its independent wars have endangered the country and obstructed recovery. Joseph Aoun’s call for state control of weapons and renewed international demands to implement Resolution 1701 place disarmament at the center of Lebanon’s political future. Whether those commitments can be enforced will determine whether Hezbollah can again turn Lebanese territory into a launch point for attacks on Israel.
