A trilateral framework agreement signed over the weekend by representatives of Israel, Lebanon and the United States marks a critical test of whether Lebanon's government can finally assert sovereignty over its own territory and confront Hezbollah, the Iranian-backed militia that has operated as a state within a state for decades. The deal, unexpectedly signed in Washington on Friday, drew immediate fury from Hezbollah — a reaction that Israeli security analysts view as confirmation that the agreement threatens the group's entrenched power.
The willingness of Lebanon to take full responsibility and to exercise its government's sovereignty in the country's south is extremely important, according to observers tracking the implementation of past agreements. But the proof of the pudding lies, as usual, in the implementation. The previous agreement, which created even more favorable conditions for Israel and was signed in November 2024, was never fully implemented and eventually collapsed. Now, much depends on the ability of Lebanon's government and army to impose their authority on Hezbollah.
The Hezbollah Challenge
Hezbollah's furious reaction to the Israel-Lebanon deal is enough to indicate good news for Israel, according to analysts familiar with the group's operations. The Iran-backed organization has long resisted any effort by the Lebanese state to assert control over southern Lebanon, where Hezbollah maintains military infrastructure and launch sites for attacks on Israeli territory. The new agreement includes provisions preventing the transfer of funds to non-state armed groups — a direct challenge to Hezbollah's financial networks and operational independence.
The Iran Factor
An official source at the U.S. State Department responded to a Haaretz inquiry on the relationship between the trilateral framework agreement and the U.S.-Iran memorandum of understanding. One of the terms of the memorandum is that the war must end on all fronts and that the parties will guarantee Lebanon's territorial integrity and sovereignty amid ongoing Israeli strikes and incursions. The contrast between Friday's Lebanon deal, which prevents the transfer of funds to non-state armed groups, and the U.S.-Iran truce, which is set to inject billions of dollars into Iran's proxy groups, makes it difficult to predict whether Beirut will manage to disarm Hezbollah.
Implementation Track Record
The agreement signed in November 2024 offers a sobering precedent. That deal, now in its second year since signing, was never fully implemented and eventually collapsed despite creating even more favorable conditions for Israel. Lebanese state institutions have repeatedly proven unable or unwilling to challenge Hezbollah's military presence in the south, leaving Israel to conduct periodic strikes and incursions to counter threats along its northern border.
Regional Strategic Picture
The trilateral framework represents an attempt to address Lebanon's sovereignty crisis within the broader context of U.S. efforts to reach a truce with Iran. The memorandum of understanding with Tehran includes guarantees of Lebanon's territorial integrity — guarantees that ring hollow as long as Hezbollah, an Iranian proxy force, maintains operational control over Lebanese territory. The fundamental contradiction between empowering the Lebanese state and simultaneously channeling billions of dollars to Iran, which funds the very militia undermining that state, raises questions about whether Washington's diplomatic strategy can succeed.
Why This Matters:
The Lebanon deal's success or failure will determine whether diplomatic agreements can compel state actors to confront Iranian proxy forces operating on their soil. If Lebanon's government and army prove unable to impose authority on Hezbollah — as they failed to do under the November 2024 agreement — Israel will face a continued security dilemma along its northern border, with a heavily armed militia answerable to Tehran rather than Beirut. The simultaneous U.S. effort to inject billions into Iran through the truce memorandum while expecting Lebanon to defund Hezbollah creates a strategic contradiction that may doom both agreements. The regional security architecture depends on whether states can reassert sovereignty over non-state armed groups, or whether Iran's proxy network will continue expanding regardless of diplomatic frameworks. For Israel, the answer determines whether its northern communities can live without the constant threat of cross-border attacks from an organization that has amassed an arsenal estimated at over 100,000 rockets and missiles.
