The European Council on Foreign Relations assessed this week that the conflict between the US-Israeli Coalition and Iran has no viable exit on current terms. The formulation is precise: Iran cannot win a conventional military contest against the combined air and naval power arrayed against it, but it can sustain a dispersed campaign of strikes against Gulf infrastructure, shipping, and diplomatic targets long enough to raise the political and economic cost of continuing. The US can degrade Iranian military capacity indefinitely, but it has not articulated what success looks like or when operations would stop.
This is the attrition calculus that governed Hezbollah's operations in southern Lebanon from the mid-1990s to 2006 — a doctrine Iran itself helped design and fund. Israel withdrew from Lebanon in 2000 after eighteen years of occupation that the Israeli public concluded was not worth the cost in soldiers and resources. The 2006 war produced a stalemate that neither side describes as a victory. In both cases, the armed force could not defeat the Israeli military. In both cases, it did not need to. It needed only to outlast the political will sustaining the operation. The United States has encountered the same dynamic in Vietnam, Iraq, and Afghanistan — conflicts where military superiority could not be converted into a definable end state, and where domestic political tolerance eroded before strategic objectives were achieved. The civilian populations of Lebanon, Israel, and now Iran and The Gulf states bore the heaviest cost across years of fighting in each precedent.
Every diplomatic channel that might produce an alternative has stalled simultaneously. UN Secretary-General Guterres called for "a way out" on Sunday; none has materialised. Turkey's President Erdogan offered mediation — Ankara has relationships with all parties, NATO membership, and an 534-kilometre border with Iran — but no formal process has begun. The Omani backchannel, which produced the earliest contacts between Washington and Tehran that led to the 2015 nuclear agreement, remains active but without a framework or agreed terms. Iran's own signals are contradictory: Ali Larijani, a senior adviser to the Interim Leadership Council, stated Iran will not negotiate with the United States, while Iran's foreign minister told his Omani counterpart that Tehran is "open to serious de-escalation efforts" through intermediaries. The same foreign minister acknowledged that military units are operating outside central government direction — which raises the question of whether any Iranian interlocutor can deliver on commitments even if talks began.
The result is a conflict sustained by its own momentum. Iran's formal rejection of ceasefire talks, announced the same day as the ECFR assessment, closes the most direct path to a pause. The E3 statement from France, the UK, and Germany condemned Iranian attacks on Gulf states but did not condemn US-Israeli strikes on Iran — a framing that disqualifies the European powers as honest brokers in Tehran's assessment. Russia and China have positioned themselves rhetorically with Iran — Putin called the strikes "unprovoked aggression" — but neither has offered a concrete diplomatic framework. No actor with the influence to compel a ceasefire is willing to use it, and no actor willing to mediate has the leverage to succeed. The war continues because no institution or state can stop it.
