A fragile ceasefire between the United States and Iran has paused a rapidly escalating conflict, but it has not clarified what comes next.
Does the ceasefire reduce Iran’s grip on the Strait of Hormuz, or entrench it further? Can Washington and Tehran narrow their differences over uranium enrichment and sanctions? And is this the start of a real de-escalation, or simply a pause driven by political necessity on both sides?
The two-week truce has pulled the region back from the brink after days of escalating strikes and threats to energy infrastructure. But much about the deal remains uncertain, with both sides offering different accounts of what has been agreed and what may come next.
What has actually been agreed
At its core, the ceasefire establishes a two-week halt in hostilities between the United States and Iran, following weeks of escalating strikes that had pushed the region towards a wider war. The truce, brokered by Pakistan, includes a pause in attacks and a commitment to reopen the Strait of Hormuz.
Beyond that, the details of the agreement remain unclear.
US officials have described a deal centred on reopening the Strait and halting military operations, but Iranian statements suggest shipping will resume under coordination with its armed forces, suggesting Tehran retains oversight. As reported by the Associated Press (AP), the two sides have offered differing accounts of even the basic terms, including the scope of the ceasefire and control over the Strait.
Key issues remain unresolved. According to Al Jazeera, proposals linked to the deal include uranium enrichment, sanctions relief and broader security guarantees, all of which remain contested. These are among the most difficult issues and are unlikely to be resolved quickly.
There is also uncertainty over the scope of the truce. Israel has indicated its operations in Lebanon will continue, highlighting its limits, while early reports of violations underline its fragility.
The announcement has been welcomed as a moment of relief, but reactions remain cautious. In a post on X, Spanish Prime Minister Pedro Sánchez warned that the temporary pause should not obscure the destruction caused by the conflict, adding that governments should not “applaud those who set the world on fire just because they show up with a bucket”.
Taken together, the ceasefire appears less like a detailed settlement and more like a temporary framework, leaving core disputes to be tested in negotiations expected to begin in the coming days.
Hormuz and the question of control
At the centre of the ceasefire is the Strait of Hormuz, a critical chokepoint for global energy flows. While the agreement includes a commitment to reopen it, what that means in practice remains contested.
US officials have insisted the Strait must be fully reopened. But Iranian statements suggest shipping will resume under the oversight of its armed forces, indicating continued control. According to Reuters, any arrangements are provisional and tied to the progress of negotiations.
There are also indications that Iran could seek to monetise its position. AP and Al Jazeera report that proposals linked to the deal include potential fees on vessels transiting the Strait, reinforcing Tehran’s leverage over global energy flows.
This points to a broader shift. Rather than resolving control over Hormuz, the ceasefire may simply redefine it, moving from disruption to managed access under Iranian influence.
Nuclear red lines remain unresolved
The ceasefire has done little to bridge one of the central disputes between the two sides: Iran’s nuclear programme.
Proposals linked to the deal include recognition of Iran’s right to enrich uranium, alongside sanctions relief. But US officials have continued to insist that enrichment remains a red line, highlighting a fundamental gap in positions.
As reported by CNN, the lack of clarity over what has been agreed has also raised concerns within Washington about potential concessions, particularly on nuclear issues. At the same time, Iran has shown little indication it is willing to abandon enrichment, a point that has derailed past negotiations.
A lasting deal will depend on both sides making compromises on the nuclear issue, but there is no sign of that yet. For now, the ceasefire leaves the problem unaddressed.
A ceasefire that may not extend across the region
The ceasefire applies to direct hostilities between the United States and Iran, but its reach beyond that remains uncertain.
Israel has made clear that its operations in Lebanon will continue, signalling that the truce does not cover all fronts linked to the conflict. That raises the risk that fighting elsewhere could undermine the pause.
There are also conflicting accounts over whether the ceasefire was ever meant to extend to Lebanon, underscoring the lack of clarity surrounding the agreement.
This points to a broader problem. While the ceasefire may stabilise the immediate crisis, it leaves wider regional tensions largely untouched.
Negotiations under pressure and a fragile outlook
The ceasefire has opened a path to negotiations, but both sides enter talks with deep mistrust and competing expectations.
Iran has made clear it will approach discussions cautiously, signalling that any arrangements, including those related to the Strait of Hormuz, remain temporary and tied to progress at the negotiating table. Iran’s ambassador to the United Nations in Geneva told Reuters that Tehran does not trust Washington and will test its intentions through talks.
Washington, meanwhile, has continued to signal firm positions on key issues, particularly the nuclear file, suggesting limited room for compromise at this stage.
That leaves both sides heading into talks with unresolved core disputes and little sign of convergence. Analysts at Chatham House note that the most difficult issues, including sanctions, nuclear constraints and regional security, are unlikely to be resolved quickly, making a breakthrough in the coming weeks unlikely.
Talks expected to begin in Islamabad will test whether the current pause can be turned into something more durable. For now, the ceasefire appears less like the start of a settlement and more like a temporary step in a longer, uncertain negotiation process rather than the beginning of a lasting settlement.
