Fragile quiet in Lebanon as US-Iran truce leaves unanswered questions

What Happened

On Monday, a ceasefire agreement between the United States and Iran—mediated by Pakistan—took effect, including a halt to hostilities in Lebanon. Hours later, displaced families began returning to southern villages like Jebchit in Nabatieh and Aadshit near Marjayoun despite government warnings, with social-media video showing an Israeli armored vehicle blocking a street. A fragile quiet holds, though both Israel and Hezbollah launched attacks over the past day. The round of conflict ignited in March when Hezbollah fired rockets into Israel after the killing of Iranian Supreme Leader Ayatollah Ali Khamenei; Israel responded with an extensive bombing campaign and invasion of southern Lebanon. According to the Lebanese health ministry, which does not separate combatants from civilians, more than 3,800 people have been killed; the IDF claims over 2,500 Hezbollah operatives killed, while Israeli authorities report 30 soldiers and four civilians dead. One million people remain displaced, mostly Shia Muslims. Unresolved questions persist: around 5% of Lebanese territory is under Israeli occupation with no withdrawal in sight; Israeli Defence Minister Israel Katz stated Israel would stay indefinitely in seized land to create a Hezbollah-free security zone. Hezbollah refuses to discuss its arsenal, and the Lebanese government says disarmament can only come through diplomacy, a distant prospect.

Key Actors

Why It Matters

The truce has the potential to end the most catastrophic Lebanon conflict since the 2024 war, but the unresolved issues of permanent Israeli occupation, Hezbollah's weapons, and reconstruction funding cast doubt on its durability. The US-Iran understanding may either curb or cement Tehran's sway in Lebanon, while Israel's insistence on a Hezbollah-free security zone risks prolonging the occupation. The fragile quiet tests whether diplomacy can supplant military action and shape the future of Israeli-Lebanese borders and Iranian proxies.

Watch For

Monitor whether the ceasefire holds amid continuing tit-for-tat attacks, and watch Israeli troop movements regarding the occupied zone and any withdrawal timeline. Hezbollah's stance on its arsenal and response to potential disarmament pressure will be critical. Track reconstruction funding pledges and the release of the full US-Iran agreement details. A resurgence of fighting could occur if Hezbollah acts on its rejection of Israeli 'freedom of action.' Also observe Lebanese government efforts to separate the Lebanon file from the Iran conflict.
