Washington increasingly treats Hezbollah as a Lebanese sovereignty challenge, making future U.S. support conditional on meaningful state action and reform.
Washington redefines the Hezbollah file
As certain contours of the emerging U.S.-Iran understanding become clearer, Lebanon does not appear to be among the beneficiaries of de-escalation. Instead, it stands out as one of the most fragile and vulnerable flashpoints. Although the agreement promises a 60-day ceasefire and a broader regional easing of tensions, it leaves the most significant issue unresolved: Hezbollah's armed presence.
In this context, U.S. President Donald Trump said yesterday that “peace in Lebanon is something we need to work on a little,” describing the Lebanese file as one that “generates a lot of noise.” According to Trump, the Hezbollah issue remains part of the broader regional equation, while emphasizing that any approach must also take into account Lebanon's own position regarding how to move forward.
Against this backdrop, the National Defense Authorization Act (NDAA) for Fiscal Year 2027, submitted by Senate Armed Services Committee Chairman Roger Wicker to the Senate on June 15, can be read as a document revealing how Washington is reshaping its security priorities in the Levant. In Lebanon’s case, U.S. sources say the message is clear: Hezbollah is no longer being treated primarily as a traditional extension of negotiations with Tehran, but rather as a direct test of Beirut’s ability to monopolize the use of force and enforce state sovereignty. From this perspective, Lebanon occupies a place in U.S. strategic calculations not as the natural beneficiary of any U.S.-Iran de-escalation, but as the arena that may ultimately expose both the limits and the fragility of that de-escalation.
This shift is reflected not only in diplomatic statements. The language contained in the draft legislation goes far beyond the traditional rhetoric of supporting the Lebanese Armed Forces or strengthening state institutions. Instead, Washington explicitly links military assistance to a specific objective: preventing Hezbollah and other organizations designated as terrorist groups from using Lebanese territory to threaten U.S. interests and regional partners, while simultaneously enhancing the state’s capacity to ultimately eliminate illicit weapons. This is not merely technical language; it represents a redefinition of the mission itself.
More importantly, this support is neither open-ended nor unconditional. The proposed U.S. approach establishes a financial ceiling, prioritizes vetted military units within the Lebanese Armed Forces, and ties the release of most funding to highly sensitive political and security conditions. The underlying logic is that continued assistance depends on the Lebanese government demonstrating, both in words and in deeds, that it no longer treats Hezbollah’s military structure as a permanent reality or a domestic issue to be indefinitely postponed, but rather as a sovereignty challenge that must be addressed through state institutions. In this sense, assistance becomes less a tool of support than a tool of measurement: Does the Lebanese state genuinely intend to change the rules of the game, and does it possess the political and security capacity to begin doing so?
The proposed oversight mechanisms further demonstrate that Washington does not view this as a symbolic gesture or a short-term pressure tactic. Under this approach, periodic reports would be required assessing the extent to which Hezbollah’s capabilities have been degraded. Even details concerning the structure and deployment of elite Lebanese Army units would become subject to review. The implication is clear: the United States seeks measurable benchmarks to determine whether Lebanon is genuinely acting against Hezbollah’s military infrastructure or merely managing the political balance surrounding it. Should Washington conclude that Lebanon possesses the capability but lacks the political will, military assistance itself could be suspended. In this regard, the NDAA represents far more than a provision within the U.S. defense budget. For Lebanon, it constitutes a comprehensive political and security framework for testing both intentions and capabilities.
Against this backdrop, Lebanon does not occupy a particularly prominent place within the U.S.-Iran memorandum of understanding. According to the leaked provisions that have been made public, the memorandum is primarily concerned with ending the broader conflict, ensuring freedom of navigation through the Strait of Hormuz, and opening a subsequent negotiating track addressing the nuclear file, sanctions, and broader regional arrangements. The Lebanese front appears within this framework merely as an extension of the cessation of hostilities, rather than as an issue that has been independently or definitively resolved.
It is here that the outlines of the U.S. strategy become particularly evident, emphasizing a clear separation between the Lebanese-Israeli conflict and the broader U.S.-Iran understanding. White House sources stressed that Israel is not a direct party to the agreement, that its withdrawal from Lebanon is not stipulated as one of its conditions, and that Israel’s right to respond, or to act in “self-defense,” remains intact should threats continue to emanate from Hezbollah or Lebanese territory. In practical terms, Lebanon could therefore find itself under a nominal ceasefire that reduces the intensity of open warfare while still allowing targeted Israeli strikes or military operations justified as preemptive or deterrent measures. Consequently, Lebanon becomes less an arena of settlement than one of ongoing risk management.
This paradox explains why Lebanon is not viewed in Washington as an automatic beneficiary of de-escalation with Iran. As political leaks suggest, the U.S. administration is separating two distinct tracks: one involving understandings with Tehran over the nuclear issue, maritime security, and preventing a broader regional war; and another dealing with Hezbollah as an armed force operating outside the authority of the Lebanese state. Embedded within this distinction is perhaps the harshest message for Beirut: even if U.S.-Iran tensions subside, the Hezbollah issue will not disappear within a broader regional bargain. Instead, it will be reclassified as a Lebanese problem to be managed, contained, and ultimately dismantled domestically, with only conditional external support.
Politically, this means that the long-standing narrative portraying Hezbollah’s weapons as an integral component of a regional deterrence balance no longer resonates in Washington as it once did. The recent war, with its destruction, displacement, and reciprocal strikes, has revived an old question in even starker terms: Who truly protects Lebanon, and who determines the costs of war and peace on its behalf? From the current U.S. perspective, the existence of an armed force operating outside state authority is no longer viewed as a guarantee of Lebanon’s security but rather as one of the country’s greatest vulnerabilities, because it enables a non-state actor to tie Lebanon to regional calculations beyond the state’s ability to endure or control.
For this reason, Washington is no longer speaking in vague terms about extending state authority without practical substance. What is now emerging is a more operational vision based on gradual, verifiable steps: expanding the Lebanese Army’s deployment, strengthening intelligence capabilities, disrupting weapons supply routes, and providing tangible evidence on the ground that the state is capable of asserting authority in areas long considered beyond its full control.
Within this context, discussions in Washington have increasingly focused on “pilot zones” serving as testing grounds for state sovereignty, beginning with Greater Beirut and its surrounding areas as the primary benchmark of seriousness. A state unable to enforce its authority in the capital will find it difficult to convince Washington, or anyone else, that it can do so in the south or along the country’s most sensitive frontlines.
Yet this approach runs into a circular dilemma that encapsulates the broader crisis. Beirut argues that continued Israeli strikes and Israel’s retention of positions inside Lebanese territory undermine the state’s ability to establish stable authority while fueling further internal tensions. Israel, in turn, argues that any withdrawal absent credible Lebanese measures to control illicit weapons would merely provide Hezbollah with the opportunity to regroup. Between these competing positions, a form of conditional stalemate has emerged: no complete Israeli withdrawal without credible Lebanese action, and no comprehensive Lebanese action while facing ongoing military pressure and the constant threat of escalation.
Ultimately, what both the Fiscal Year 2027 National Defense Authorization Act and Lebanon’s place within the U.S.-Iran memorandum of understanding reveal is that Washington is not offering Beirut a ready-made settlement. Instead, it is presenting a difficult equation: continued support, but under strict conditions; regional de-escalation, but without an umbrella that automatically resolves the Hezbollah issue; and an opportunity to rebuild the state, but only if that state demonstrates that it is prepared to seize the moment.
