GENEVA / WASHINGTON / TEHRAN — After more than three months of war, economic disruption, and fears of a broader regional conflagration, the United States and Iran have reached a preliminary agreement that could halt hostilities and reopen one of the world’s most strategically important maritime corridors. Yet even as leaders celebrate the breakthrough, fundamental questions remain unanswered.
President Donald Trump announced that the deal is effectively complete and that a formal signing is expected in Geneva on June 19. Iranian officials have similarly confirmed that a memorandum of understanding has been finalized. The peace agreement establishes a 60-day ceasefire and creates a framework for subsequent negotiations on the most contentious issues dividing Washington and Tehran.
But analysts caution that this is not yet a comprehensive peace agreement. Instead, it is an agreement to continue negotiating while temporarily stopping the fighting.
Question 1: What Happens to Iran’s Nuclear Program?
The future of Iran’s nuclear program remains the single biggest unresolved issue.
The preliminary agreement reportedly postpones substantive negotiations over uranium enrichment, Iran’s stockpiles of enriched material, and long-term verification mechanisms. While there are indications that future arrangements could limit Tehran’s nuclear activities, no final framework has yet been agreed upon.
This ambiguity has fueled skepticism among security experts and lawmakers. Critics argue that a temporary ceasefire without clear nuclear commitments risks merely delaying a confrontation rather than preventing one.
Supporters counter that securing an immediate cessation of hostilities and creating diplomatic space may represent the best opportunity in years to address one of the world’s most dangerous nuclear flashpoints.
Question 2: Will the Strait of Hormuz Truly Reopen?
The agreement’s most immediate economic consequence involves the reopening of the Strait of Hormuz, through which roughly one-fifth of global oil supplies normally transit.
Iran has reportedly agreed to unblock shipping routes, while the United States would ease certain restrictions and suspend its naval blockade. Markets have responded positively to the prospect of renewed energy flows and reduced risks of supply disruptions.
Yet significant uncertainties remain.
Who will manage maritime traffic? Will Iran impose future transit fees? How long will unrestricted passage remain in place? None of these questions has been definitively resolved. Analysts warn that disagreements over shipping governance could quickly become new sources of tension.
Question 3: What Does Sanctions Relief Actually Mean?
Iran’s economy has been battered by war and sanctions, making economic relief one of Tehran’s top priorities.
Reports indicate that the peace agreement contemplates phased sanctions relief, possible unfreezing of assets, and discussions surrounding a potential $300 billion reconstruction and investment framework funded largely by Gulf capital. However, nearly all of these benefits appear to be contingent upon future Iranian actions and subsequent agreements.
Iranian hardliners have already questioned whether the arrangement provides sufficient guarantees that promised economic benefits will ever materialize.
Likewise, critics in Washington argue that granting significant economic concessions before securing firm nuclear commitments could undermine American leverage.
Question 4: Can Regional Stability Actually Last?
Perhaps the greatest uncertainty concerns the broader Middle East.
The memorandum reportedly does not resolve questions surrounding Iran’s ballistic missile program, its relationships with regional proxy groups, or Israel’s ongoing military operations in Lebanon and elsewhere. Israel, which was not directly involved in the negotiations, has signaled that it intends to maintain military pressure against perceived threats.
Meanwhile, Gulf Arab states are reassessing their security assumptions after emerging from the conflict with renewed doubts about the reliability of traditional deterrence arrangements. Some governments are increasingly pursuing diplomatic engagement with Tehran while simultaneously diversifying their strategic partnerships.
A Deal Built on Fragile Foundations
The peace agreement has unquestionably achieved something significant: it halted a war that threatened global energy supplies, destabilized markets, and raised fears of a wider regional conflict.
Yet nearly every issue that caused the crisis in the first place remains unresolved.
The nuclear file is unfinished. Sanctions relief is conditional. The future governance of the Strait of Hormuz is uncertain. Regional rivalries continue.
For now, the U.S.-Iran agreement appears less like a final peace settlement and more like a diplomatic bridge suspended over unresolved disputes. Whether it ultimately becomes the foundation for a lasting peace—or merely a pause before another crisis—may depend entirely on what happens during the next sixty days.
