Iran Update Special Report, June 4, 2026

Key Points:

• Hezbollah and Iranian leaders reject any ceasefire in Lebanon that does not demand total Israeli withdrawal, linking this stance to Iran's broader negotiations with the United States, especially over control of the Strait of Hormuz.
• The US, Israel, and Lebanon agreed on June 3 to implement a ceasefire contingent on Hezbollah halting attacks and withdrawing south of the Litani River, with Lebanese Armed Forces deploying to southern zones to exclude non-state actors.
• Iran uses the Lebanon conflict to deflect from critical US-Iran negotiation points on its nuclear program and control over the Strait of Hormuz, demanding immediate economic relief and asserting legal justifications for its actions in the strait.
• The Iraqi federal government is working to disarm and integrate Iranian-backed militias, including Saraya al Salam, into state security forces, though some militias like Kataib Hezbollah refuse disarmament until foreign troops withdraw.
• Without addressing militias' allegiance to Iran, efforts to integrate them into Iraqi security institutions risk deepening Iranian influence within Iraq’s state apparatus and compromising the effectiveness and integrity of Iraqi security forces.
