The future of the United Nations peacekeeping mission in southern Lebanon will be decided this week as the UN Security Council prepares to vote on whether to renew or begin winding down the long-standing operation.
The United States and Israel are said to be pushing for the gradual closure of the United Nations Interim Force in Lebanon (UNIFIL), with a complete withdrawal proposed by August 2026. A French-drafted compromise resolution would extend UNIFIL’s mandate for another year while laying the groundwork for a phased exit.
UNIFIL was first established in 1978 following Israel’s invasion of Lebanon, with the aim of maintaining calm along the so-called “blue line” separating the two countries. The force has grown into one of the UN’s longest-running peacekeeping missions, with troops deployed from dozens of contributing nations. Ireland, which has participated since UNIFIL’s creation, currently has more than 300 Defence Forces personnel serving in the mission — its largest overseas deployment.
Ireland’s Tánaiste, Simon Harris, is intensifying diplomatic efforts to secure the mandate’s renewal. He is due to meet French Foreign Minister Jean-Noël Barrot in Paris today as part of a coordinated campaign to build consensus among Security Council members.
“As the current mandate is set to expire on Sunday, I want to reaffirm Ireland’s strong support for its renewal,” Harris said ahead of the talks. “UNIFIL has played a vital role in maintaining peace and security in a volatile region, and winding down the mission now would be deeply problematic for Lebanon and for countries that have contributed troops.”
Harris noted that Ireland has been in active discussions with the United States, Italy, Lebanon, and UN officials in recent weeks. He said Ireland remained “deeply conscious” of the importance of the mission both to regional stability and to the credibility of international peacekeeping.
While Washington and Tel Aviv argue that the mission has outlived its purpose, other Security Council members are believed to support its continuation. France has led efforts at UN headquarters in New York to preserve the mandate, with diplomats warning that a premature withdrawal could destabilize the border and undermine Lebanon’s already fragile security situation.
A senior UN official cautioned that eliminating UNIFIL’s presence too quickly “would not serve anybody in the region.” The official pointed out that the mission had enabled the deployment of 8,300 Lebanese armed forces personnel to 120 locations, providing critical logistical, financial and training support.
UN spokesman Stephane Dujarric reinforced this view, calling UNIFIL’s assistance to Lebanon’s army “critical” and describing the peacekeepers as a “presence of stability along the blue line.”
The Security Council’s decision, expected later this week, will shape not only Lebanon’s security landscape but also the broader role of UN peacekeeping at a time when missions around the world are facing mounting political and financial pressures.
