Why is it in News ?
- From 16 March 2026: Israel launched a ground offensive in southern Lebanon against Hezbollah, alongside massive air strikes in Beirut suburbs, escalating regional instability.
- The conflict is linked to the broader Israel–Iran confrontation, especially after the killing of Ayatollah Ali Khamenei (28 Feb 2026), triggering retaliatory attacks by Hezbollah.
- The crisis marks a breakdown of the November 2024 ceasefire, raising concerns of a full-scale regional war in West Asia.

Practice Question
- Q. “The Israel–Hezbollah conflict reflects the changing nature of warfare from state-centric to proxy and hybrid conflicts.” Analyse its regional implications. (250 words)
Static background: Israel–Lebanon conflict
Historical roots
- 1978 & 1982 Israeli invasions of Lebanon aimed to push out Palestine Liberation Organisation (PLO) fighters from southern Lebanon beyond the Litani River.
- The 1982 invasion indirectly led to the rise of Hezbollah, backed by Iran after the 1979 Islamic Revolution, as a Shia resistance force.
Evolution of Hezbollah
- Hezbollah emerged as a militant + political organisation, often described as a “state within a state” in Lebanon, due to its independent military capability.
- Israel withdrew from southern Lebanon in 2000, marking Hezbollah’s first major success against Israel, strengthening its regional legitimacy.
2006 war
- The 2006 Israel–Hezbollah war ended in a ceasefire without decisive victory, but Hezbollah retained its military strength and expanded its arsenal significantly.
What is Hezbollah today ?
- Hezbollah possesses tens of thousands of rockets and missiles, making it one of the most powerful non-state armed groups globally.
- It is backed by Iran (funding, weapons, training) and historically connected through Syria as a land corridor for arms supply.
- It combines guerrilla warfare tactics with conventional capabilities, posing a hybrid threat to Israel’s northern borders.
Triggers of current conflict
- October 7, 2023 Hamas attack on Israel triggered regional escalation, with Hezbollah opening a northern front by firing rockets into Israeli territory.
- Israel retaliated with continuous air strikes, leading to displacement of civilians in northern Israel (Upper Galilee region).
- September 2024: Israel assassinated Hezbollah leader Hassan Nasrallah, weakening its command structure temporarily.
- February 2026: Killing of Iran’s Supreme Leader Khamenei by U.S.-Israel intensified conflict, prompting Hezbollah to launch hundreds of rockets into Israel.
Why ground offensive is concentrated in southern Lebanon ?
- Southern Lebanon is Hezbollah’s stronghold, especially in hilltop towns like Khiam, offering strategic advantage over Israeli territory (Hula Valley).
- The region lies south of the Litani River, historically seen by Israel as a buffer zone to prevent cross-border attacks.
- Control over this region disrupts Hezbollah’s logistics, supply routes, and missile launch capabilities, making it a primary military objective.
Why Israel wants to dismantle Hezbollah ?
- Israel considers Hezbollah an “Iranian proxy”, posing an existential threat due to its proximity and missile capabilities targeting northern Israeli cities.
- Hezbollah’s arsenal includes precision-guided missiles and drones, capable of overwhelming Israel’s Iron Dome defence system.
- Past attempts (2000, 2006) failed to neutralise Hezbollah, making current operations aimed at achieving long-term deterrence and security buffer.
What Israel aims to achieve ?
- Destroy Hezbollah’s military infrastructure and leadership, reducing its operational capability to launch attacks against Israel.
- Push Hezbollah forces north of the Litani River, creating a buffer zone inside Lebanese territory for strategic depth.
- Pressure the Lebanese government to disarm Hezbollah, aligning with UN resolutions like UNSCR 1701 (2006).
- Disrupt Iran–Hezbollah supply chain, especially after the collapse of Assad regime (Dec 2025) weakened the Syria corridor.
Hezbollah’s response and strategy
- Hezbollah claims it is defending Lebanese sovereignty against Israeli aggression and occupation attempts.
- It has launched over 1,000 rockets and drones (since March 2026), signalling continued offensive capability despite leadership losses.
- Uses asymmetric warfare tactics:
- Guerrilla attacks
- Terrain advantage in hill regions
- Decentralised command structure
Regional geopolitical context
- The fall of Bashar al-Assad regime (Dec 2025) broke the Iran–Syria–Hezbollah axis, weakening logistical connectivity.
- Russia’s distraction in Ukraine and limited Iranian manoeuvrability reduced support to Hezbollah.
- Rise of groups like Hayat Tahrir al-Sham (HTS) altered Syria’s power balance, indirectly benefiting Israel’s strategic position.
Humanitarian impact
- Over 1,000 people killed and nearly 1 million displaced in Lebanon due to Israeli air strikes and ground operations.
- Civilian infrastructure, including bridges across Litani River, targeted, worsening humanitarian crisis.
- Lebanese civilians remain caught between state weakness and militant–state conflict dynamics.
Challenges and risks
- High risk of regional escalation, potentially drawing in Iran, Syria, and other non-state actors into a wider war.
- Weak Lebanese state capacity limits ability to disarm Hezbollah, complicating conflict resolution.
- Urban warfare in southern Lebanon increases civilian casualties and humanitarian law violations concerns.
- Past failures (2000, 2006) show difficulty in eliminating entrenched non-state actors through military means alone.
Way forward
- Immediate ceasefire negotiations under UN or multilateral mediation to prevent further escalation and humanitarian catastrophe.
- Strengthening implementation of UNSCR 1701, ensuring Hezbollah withdrawal north of Litani River and deployment of Lebanese armed forces.
- Revival of regional diplomacy involving Iran, Israel, and global powers to address proxy conflicts and security dilemmas.
- Long-term solution requires political integration of Hezbollah within Lebanese state structures, reducing its independent military role.
Prelims pointers
- Litani River: strategic river in Lebanon, historically used as a reference line for buffer zones.
- UNSCR 1701 (2006): calls for ceasefire and Hezbollah withdrawal north of Litani River.
- Hezbollah: Shia militant and political organisation backed by Iran.
- 2006 Israel–Hezbollah war ended without decisive victory, leading to continued instability.
