Can a third party guarantee the peace between Lebanon and Israel?

Lebanese President Joseph Aoun met with US President Donald Trump in Washington last week to discuss a US-brokered framework for peace between Lebanon and Israel. The framework aims to end the state of hostility between the two nations, focusing on Hezbollah's disarmament, strengthening the Lebanese Armed Forces (LAF), and an Israeli withdrawal from Lebanese territory. Israeli forces have begun withdrawing from southern Lebanon, allowing LAF units to deploy in "pilot zones" to test the state's ability to assume exclusive security responsibility. Marwan Abdallah of the Lebanese Kataeb Party emphasized the need for continued external guarantees, stating, "You need a third entity, and I think the US army is the partner of the Lebanese armed forces and, of course, is the partner of the Israelis, so they can play a role in being the monitoring side and being the one that guarantees the agreement between both sides." The success of this phase depends on sustained LAF performance, Israeli confidence, and Hezbollah dismantling its military infrastructure. Additionally, President Trump announced the reversal of a 1985 restriction, allowing US airlines to operate direct flights to Lebanon, a move seen as symbolic of renewed trust and Lebanon's efforts to reposition itself internationally.
