See it on the Geopolitics map →The picture
Formed during Israel's 1982 invasion of Lebanon, its guerrilla war helped push Israel out of the south in 2000, and it fought Israel to a standstill in 2006. It also sits in Lebanon's parliament and runs social services. After October 2023 it fired on Israel to support Hamas; in 2024 Israeli pager attacks and an invasion battered it, and an airstrike killed leader Hassan Nasrallah. It joined the 2026 Iran war; Lebanon's government then banned its military activity, but leader Naim Qassem refuses to disarm.
Why it matters
Its arsenal, once estimated at 150,000 rockets, made it Iran's main deterrent against Israel; its weakening gives Lebanon's state its first real chance to monopolize arms.
Key facts and numbers
Israeli and Lebanese government statements, UN reports on Security Council Resolution 1701, the US terrorist designation (1997) and Hezbollah's own speeches. Arsenal and casualty figures are estimates.
What to watch
Open: whether Lebanon's army can disarm Hezbollah north of the Litani River without civil strife, and how much of its arsenal survived.

▸Iran's 'Axis of Resistance' (allied militias) includes Hezbollah (Lebanon)Fact
The relationship
Hezbollah is the axis's oldest and strongest member. Iran's Revolutionary Guards helped found it in 1982 and supplied hundreds of millions of dollars a year, plus rockets and missiles trucked through Syria. In return it trained other allied militias and served as Iran's front line against Israel.
Since when and why
Lebanon's Bekaa Valley, 1982, with Revolutionary Guards advisers; supply routes ran through Assad's Syria until December 2024.
How we know
Hezbollah leaders openly acknowledged Iranian funding and arms; US State Department estimates (about $700 million a year, 2018) and intercepted weapons shipments.
What to watch
With Syria lost and Iran at war, how Hezbollah rearms, and whether it now acts more as a Lebanese party than an Iranian arm, is debated.
▸Hezbollah (Lebanon) has repeatedly fought IsraelFact
The relationship
Hezbollah's guerrilla war helped end Israel's occupation of south Lebanon in 2000. They fought a 34-day war in 2006 and traded fire from October 2023; Israel's 2024 offensive killed Nasrallah before a November ceasefire. Hezbollah fired again on March 2, 2026; Israel invaded the south and has pressed for its disarmament through US-brokered talks with Lebanon.
Since when and why
Southern Lebanon and northern Israel: 1985–2000, July–August 2006, October 2023–November 2024, and since March 2026, with US-brokered ceasefire arrangements in April and June 2026.
How we know
Military statements from both sides, UN peacekeeping (UNIFIL) reports, Lebanese health ministry casualty counts and US State Department readouts of the 2026 talks.
What to watch
Unclear whether Israel will withdraw from south Lebanon and whether Hezbollah's weakening is permanent; casualty estimates vary by source.
