What it is
Hezbollah ("Party of God") is a Lebanese Shia political and military organisation founded in the early 1980s during the Lebanese civil war. It is both a parliamentary party with elected representation and an armed organisation with capabilities approaching those of a small state military. The political and military wings are integrated in the movement's own framing; some external designations distinguish them.
Capabilities
- Precision-guided missile arsenal of substantial size (numbers contested across sources).
- Anti-ship cruise missile capability.
- Drone fleets including loitering munitions.
- A deep network of fortified positions in southern Lebanon.
- Cyber and information-operations capability.
Iran relationship
Hezbollah's relationship with Iran — and specifically with the IRGC-Quds Force — is the closest of any non-state actor. Material, training, and operational coordination are continuous rather than episodic. The movement operates as part of Iran's regional deterrent architecture without being an extension of Iranian command.
Why Israel watches it closely
Hezbollah is the principal vector by which Iran can credibly threaten northern Israel. Israeli security planning has for two decades incorporated the Hezbollah northern-front scenario as a baseline threat. Periodic exchanges across the Lebanon-Israel border, Israeli targeting of senior Hezbollah leadership, and Israeli operations against Hezbollah resupply routes in Syria are all instances of the longer deterrence dispute.
