The ceasefire between the United States, Iran and Israel was never a fully aligned agreement but rather a convergence of temporary interests. Each party entered the deal with different assumptions about its scope and conditions.
This divergence became immediately visible as Israeli airstrikes in Lebanon continued, killing hundreds and exposing a core dispute: Iran views Lebanon as integral to the ceasefire, while Israel explicitly excludes it.
Rather than halting conflict, the agreement has effectively frozen one layer of war while allowing another to continue.
Lebanon as the Strategic Fault Line
Lebanon is central not because it is formally part of the war, but because it is structurally embedded in Iran’s regional power projection.
Since the 1979 revolution, Iran has cultivated a network of allied armed groups across the region. The most significant of these is Hezbollah, which functions as both a military force and a political actor within Lebanon.
Alongside Hamas in Gaza and the Houthis, Hezbollah forms part of a broader deterrence architecture designed to project Iranian influence and constrain Israeli military freedom.
For Israel, these actors are not peripheral threats but immediate ones. Under Benjamin Netanyahu, Israeli strategy has prioritised degrading these groups and establishing buffer zones beyond its borders, including in southern Lebanon.
This makes Lebanon the geographic and strategic intersection where Iranian influence and Israeli security doctrine directly collide.
Contradictory War Aims
At the heart of the ceasefire’s fragility are incompatible objectives:
- The United States, under Donald Trump, seeks a controlled de escalation that allows it to disengage while claiming success
- Iran seeks to preserve its regional influence, particularly its proxy network
- Israel seeks to permanently weaken or eliminate proximate threats like Hezbollah
These goals cannot be simultaneously satisfied. Any concession to Iran on Lebanon undermines Israel’s security doctrine, while Israeli operations in Lebanon directly challenge Iran’s red lines.
The Proxy War Continuum
The current situation highlights a key reality: the US Iran war and the Iran Israel proxy conflict are not separate theatres but interconnected layers of a single regional struggle.
Even as direct confrontation pauses, the proxy war continues unabated. Hezbollah’s rocket fire and Israeli retaliation demonstrate that the underlying conflict dynamics remain active.
For Iran, abandoning Hezbollah would mean dismantling a core pillar of its regional strategy. For Israel, tolerating Hezbollah’s presence near its border is strategically unacceptable.
This ensures that Lebanon remains a live battlefield regardless of diplomatic developments elsewhere.
Limits of US Leverage
A critical question is whether the United States can enforce alignment within its own camp. Historically, Washington has had influence over Israeli decision making, but that influence is not absolute.
There is little indication that Trump is willing to exert sustained pressure on Netanyahu to halt operations in Lebanon. More importantly, it is unclear whether he views doing so as strategically necessary.
This weakens the credibility of the ceasefire framework, as one party to the agreement is effectively continuing military operations that another party considers central to the deal.
The Iran Position and Identity Factor
Iran’s stance on Lebanon is not purely strategic but ideological. Opposition to Israel and support for allied movements like Hezbollah are deeply embedded in the identity of the Iranian regime.
This limits Tehran’s flexibility in negotiations. Even if its military capabilities have been degraded, its political commitment to resisting Israel remains intact.
As a result, Iran is unlikely to accept any agreement that allows Israel to freely operate against Hezbollah.
Implications for the Ceasefire
The ceasefire is unlikely to hold in its current form. At best, it may function as a temporary pause in direct US Iran confrontation while proxy conflicts intensify.
At worst, continued violence in Lebanon could trigger a full collapse of negotiations, drawing the United States back into escalation or forcing a premature withdrawal.
The most probable outcome lies in between: a gradual erosion of the agreement as violations accumulate and trust diminishes.
A Flawed Exit Strategy
Trump’s approach suggests a focus on short term political gains rather than long term conflict resolution. With domestic pressure rising, the incentive is to declare success and disengage, even if underlying tensions remain unresolved.
This is reflected in the sudden acceptance of negotiation frameworks that previously seemed unacceptable, including aspects of Iran’s proposed terms.
However, these proposals include conditions fundamentally at odds with US and Israeli positions, such as Iranian control over key strategic areas like the Strait of Hormuz and the right to continue uranium enrichment.
This indicates that the ceasefire is less a product of changing realities on the ground and more a reflection of shifting political priorities in Washington.
Long Term Regional Outlook
Even if the United States exits the conflict, the underlying drivers of instability will persist:
- Iran will continue to rely on proxy networks to project influence
- Israel will continue preemptive and retaliatory operations against those networks
- Regional flashpoints like Lebanon will remain active zones of confrontation
This suggests a return to a familiar pattern of cyclical escalation rather than a transition to lasting peace.
Analysis
The ceasefire is not failing because of Lebanon. It is failing because Lebanon exposes what was always true: the agreement does not reconcile the core strategic and ideological conflicts in the region.
Lebanon is the pressure point where these contradictions surface most clearly. It is where Iran’s regional ambitions and Israel’s security imperatives directly clash, and where US diplomacy appears least capable of imposing coherence.
Without addressing these foundational tensions, the ceasefire is unlikely to evolve into a durable settlement. Instead, it risks becoming another temporary pause in a conflict defined by persistence rather than resolution.
