Missiles Fly, Talks Continue: The Four Biggest Sticking Points Blocking US-Iran Peace

Last Updated:July 10, 2026, 09:34 IST

If the nuclear issue has dominated negotiations for years, the Strait of Hormuz has emerged as the newest and perhaps most volatile sticking point.

Fresh US strikes on Iranian targets and Tehran’s retaliatory attacks on American military facilities have once again raised doubts over whether diplomacy between the two countries can survive. Yet, even as missiles continue to fly, Washington has maintained that technical-level talks with Iran remain on track, signalling that neither side has completely walked away from negotiations.

That may seem contradictory, but it reflects the current reality of US-Iran relations. Months of indirect negotiations have produced an interim understanding that halted some hostilities and reopened diplomatic channels, but they have failed to resolve the core disputes that have defined the relationship between Tehran and Washington for decades.

The latest military escalation has not created these disagreements, but it has merely exposed how unresolved they remain.

The Sticking Points Between US And Iran

Iran’s Nuclear Programme: Still A Hurdle

The nuclear issue continues to be the heart of the negotiations.

The United States wants Iran to permanently prevent the development of a nuclear weapon through strict limits on uranium enrichment, tighter international inspections and verifiable safeguards. Iran, meanwhile, insists it has the sovereign right to enrich uranium for civilian purposes under the Nuclear Non-Proliferation Treaty and argues that its nuclear programme is peaceful.

The interim understanding reached in June outlined broad commitments on reducing highly enriched uranium and expanding oversight, but several technical questions remain unresolved. These include how much uranium Iran can retain, where existing stockpiles would be stored, who would monitor compliance and what would happen if either side alleged violations.

With trust between Washington and Tehran at one of its lowest points, verification has become almost as contentious as enrichment itself.

Sanctions Relief: Iran Wants Guarantees, US Wants Compliance

Iran has repeatedly argued that any meaningful agreement must provide tangible economic benefits.

Years of US sanctions have restricted Iranian oil exports, frozen overseas assets and isolated much of the country’s financial system. Tehran wants sanctions lifted quickly and seeks guarantees that future US administrations cannot simply abandon another agreement, as happened after Washington withdrew from the 2015 nuclear deal.

The United States, however, favours a phased approach, linking sanctions relief to verified Iranian compliance. American officials have also indicated that some sanctions related to terrorism and human rights may remain even if a nuclear agreement is reached.

This sequencing – whether sanctions should be lifted before or after Iran fulfils its commitments – remains one of the toughest issues at the negotiating table.

Strait of Hormuz: The Biggest Flashpoint

If the nuclear issue has dominated negotiations for years, the Strait of Hormuz has emerged as the newest and perhaps most volatile sticking point.

The narrow waterway carries roughly one-fifth of the world’s seaborne oil trade, making it one of the most strategically important shipping routes on the planet.

Following months of conflict, Iran has increasingly portrayed control over Hormuz as a matter of national sovereignty and strategic leverage. Tehran argues that it should play a central role in regulating security in the strait, while the United States and Gulf allies insist that international shipping cannot be subject to unilateral Iranian control.

Disagreements over the wording of the interim agreement have only added to the tensions. Iran believes the deal acknowledges a greater role for it in managing the waterway, while Washington rejects that interpretation and maintains that freedom of navigation must remain non-negotiable.

The latest attacks around the Gulf underline how quickly this dispute can spill over into military confrontation.

Regional Proxies And Missile Capabilities

The negotiations are about far more than Iran’s nuclear programme.

The United States and its regional partners want Iran to curb support for armed groups across West Asia, including Hezbollah in Lebanon, the Houthis in Yemen and other Tehran-backed militias. Washington also wants restrictions on Iran’s ballistic missile programme, arguing that both issues are inseparable from regional security.

Iran rejects that premise. It says its missile programme is defensive and insists its relationships with regional allies are sovereign foreign policy decisions rather than bargaining chips in nuclear negotiations.

Because these issues extend well beyond the nuclear file, they have proven particularly difficult to resolve.

Talks Continue Despite The Fighting

The renewed exchange of strikes has undoubtedly complicated diplomacy, but it has not ended it. US officials have said technical negotiations are continuing despite the latest attacks, suggesting both sides still see value in preventing the conflict from expanding into a full-scale regional war.

Whether those talks ultimately succeed will depend not on the latest military exchange, but on whether US and Iran can bridge differences over four issues that have frustrated negotiators for years: Iran’s nuclear ambitions, sanctions relief, control of the Strait of Hormuz and Tehran’s regional military footprint.
