Israel–Hezbollah

What it is

Israel–Hezbollah describes the armed confrontation between Israel and Hezbollah, a Lebanese Shia Islamist organisation that functions as a political party, a social services network, and a paramilitary force. Hezbollah holds 13 seats in Lebanon's 128-member parliament, has participated in Lebanese cabinets since 2005, and, before the 2024 war, maintained an arsenal estimated at 150,000 to 200,000 rockets and missiles, making it the world's most heavily armed non-state actor. Iran's Islamic Revolutionary Guard Corps provided founding training and financing worth hundreds of millions of US dollars annually. The United States designated Hezbollah a terrorist organisation in 1997; the European Union designated its military wing in 2013; the United Kingdom followed in 2019. The confrontation is a durable state of enmity, with major eruptions in 1993, 1996, 2006, and 2023 to 2026.

History

Hezbollah emerged in Lebanon in 1982 during Israel's invasion, supervised by Iran's IRGC in the Bekaa Valley. It formally announced itself in 1985. Israel occupied a security zone in southern Lebanon from 1985 until May 2000, when it withdrew unilaterally; Hezbollah declared victory and positioned itself as the first Arab force to achieve a military defeat of Israel. The 2006 Lebanon war began July 12, 2006, when Hezbollah captured two Israeli soldiers in a cross-border raid. Thirty-four days of fighting killed roughly 1,200 Lebanese and 160 Israelis. UN Security Council Resolution 1701, adopted unanimously on August 11, 2006, called for a ceasefire, UNIFIL expansion to 15,000 troops, and Hezbollah's disarmament south of the Litani River. None of the disarmament provisions were implemented. Hassan Nasrallah, secretary-general from 1992, oversaw Hezbollah's military build-up until his death in September 2024.

Current state

On October 8, 2023, one day after Hamas attacked Israel, Hezbollah opened a cross-border front citing solidarity with Palestinians. Attritional exchanges escalated in September 2024, when Israel launched a ground invasion of southern Lebanon and targeted strikes that killed most of Hezbollah's senior leadership. Nasrallah was killed September 27, 2024; Naim Qassem became secretary-general in October 2024. A US-brokered ceasefire took effect November 27, 2024, requiring Hezbollah to withdraw north of the Litani River and Israel to pull back within 60 days; both sides violated the terms, with Israel striking southern Lebanon almost daily. The ceasefire collapsed in March 2026 after Hezbollah launched missiles and drones into Israel following the killing of Iranian Supreme Leader Ali Khamenei. Israeli operations displaced more than 1.1 million Lebanese by month's end. As of July 2026, Qassem declared the Trilateral Framework signed June 26 null and void (see 헤즈볼라, 레바논-이스라엘 프레임워크 '무효' 선언, 서명 이틀 후 이스라엘 공격 재개).

Relationships

Hezbollah is Iran's most capable external partner. Tehran supplied founding training and weapons worth hundreds of millions of US dollars annually through the IRGC Quds Force. Syria under the Assad government provided the primary arms transit corridor; that route was significantly disrupted by Syria's political transition in late 2024 and 2025. Inside Lebanon, Hezbollah operates as a parliamentary party and social services provider, yet commands forces that the Lebanese Armed Forces cannot disarm or direct. The Lebanese state has failed to meet disarmament obligations under UN Security Council resolutions 1559, 1680, and 1701 (see 이스라엘-헤즈볼라 휴전 갱신, 그러나 무장 해제는 거부되고 공격은 계속된다). Israeli military doctrine treats Hezbollah's presence in southern Lebanon as existential. Israeli Prime Minister Benjamin Netanyahu stated in June 2026 that Israeli forces will remain there indefinitely (see 네타냐후, 레바논·시리아·가자 철수 거부).

What to watch

Whether the Trilateral Framework survives Hezbollah's formal rejection or collapses into renewed exchanges. Hezbollah's capacity to rearm after significant 2024 losses and whether Iran can restore the weapons pipeline through alternative routes. Lebanon's elections, postponed to 2028, and whether Hezbollah's political standing among Shia Lebanese holds after the 2026 displacement. The UNIFIL mandate south of the Litani River and whether Lebanese Armed Forces can deploy to the buffer zone in practice. The broader Iran-Israel ceasefire trajectory, which determines whether Hezbollah faces another Israeli military campaign or a negotiated standoff.
