Israel and Lebanon signed a Trilateral Framework agreement with the United States on June 26, 2026, after four days of negotiations in Washington mediated by the Trump administration — the most structured diplomatic instrument to emerge from the Israel-Lebanon conflict since the November 2024 ceasefire.

The framework, published by the State Department, establishes a structured process for the Lebanese Armed Forces (LAF) to restore effective sovereign authority over all Lebanese territory and for Hezbollah's military infrastructure to be disarmed and dismantled. Critically, both Israel and Lebanon affirm, on the record, the right of each state to exist in peace and their mutual desire to live as neighboring sovereign states — language that, for Lebanon, carries domestic political weight given Hezbollah's long-standing veto over such formulations.

A trilateral Military Committee is created under the accord, per Secretary of State Rubio, to oversee implementation. The agreement also conditions Israeli withdrawal on the removal of threats to Israeli citizens — effectively tying the pace of any IDF pullback to verifiable LAF enforcement on the ground.

The road to June 26

This agreement did not arrive cleanly. The June 3 joint statement from the fourth high-level trilateral meeting, released by State, already outlined a ceasefire contingent on a complete cessation of Hezbollah fire — but within 24 hours, Hezbollah rejected those terms and Israel's Defence Minister stated publicly that operations in Lebanon would continue regardless. A U.S.-brokered ceasefire announced for June 19 — to begin at 4 p.m. local time — went forward according to a senior U.S. official cited by Reuters, but Hezbollah's posture remained a live variable throughout.

Hezbollah was excluded from the Washington negotiations entirely, per NBC News. The group has also rejected the ceasefire terms embedded in the framework. That is the central operational problem the agreement now faces.

Lebanese President Joseph Aoun, speaking after the signing, framed the deal in sovereign restoration terms: Lebanese should be able to return to fully liberated land and rebuild without restriction from any armed partner — a pointed formulation aimed at Hezbollah's historical claim to operate independently of the Lebanese state in the south. Reuters reported Aoun's remarks on the same day Israel was still dropping warning leaflets over at least one southern Lebanese town, illustrating the gap between the diplomatic document and conditions on the ground.

What the framework actually requires

The Trilateral Framework's disarmament provisions sit at the harder end of what Lebanon has ever formally committed to. UN Security Council Resolution 1701 — which ended the 2006 war — required Hezbollah's disarmament in principle; it was never implemented. This framework, by contrast, creates a named institutional mechanism (the Military Committee) and ties Israeli withdrawal explicitly to enforcement progress.

Whether the LAF can deliver is a separate question from whether Beirut has now legally committed to try. The LAF has historically lacked both the capacity and the political protection to confront Hezbollah directly. Under a post-October 7 regional environment, with Hezbollah's military wing significantly degraded after more than a year of Israeli strikes and its Iranian patron under its own pressures, the political calculus in Beirut has shifted — but the security calculus on the ground remains unresolved.

The background here is worth holding: an earlier IDF withdrawal framework set a 60-day implementation window, per a January 2025 statement from the Israeli Prime Minister's Office. That timeline elapsed without full withdrawal materializing, which is part of why a more structured trilateral mechanism was needed.

For Washington, this is an attempt to close the loop that the November 2024 ceasefire left open — that agreement halted active fighting but made no enforceable provision for Hezbollah's arms. The framework assigns accountability: the LAF must act, the Military Committee must verify, and Israel retains explicit justification to stay until the threat is removed.

Hezbollah's rejection is the clearest near-term stress test. The group retains armed capacity and political constituencies in Lebanon. If the LAF is unable or unwilling to move against Hezbollah's infrastructure, the Military Committee will face an immediate credibility problem, and the conditionality written into Israel's withdrawal commitment will become the framework's defining clause rather than a procedural footnote.
