Pakistan races against time to get Iran back to US talks as truce end nears

Rising tensions at sea

These public statements follow the latest flashpoint between the two rivals, who have been at war since the US-Israeli attacks on Iran on February 28.

On Sunday, US naval forces fired on the Iranian-flagged cargo ship Touska in the Gulf of Oman and boarded it after it attempted to pass through a naval blockade that the US has enforced against Iran-linked ships trying to pass through the Strait of Hormuz since April 13. Tehran called the incident a ceasefire violation and demanded the immediate release of the ship, its crew members and their families.

Iran’s Foreign Ministry described the seizure as “extremely dangerous” and “criminal”, warning that Tehran “will use all its capacities” to defend its national interests.

On Tuesday, the US announced that its forces had also boarded a second ship, this time in the Asia Pacific. The ship, cargo vessel M/T Tifani, was already under US sanctions for carrying Iranian oil.

For Javad Heiran-Nia, a researcher specialising in Iranian affairs, the Touska incident may nonetheless offer a narrow opening.

“The release of the ship’s crew could be a green light for Iran to soften its position on returning to talks,” he told Al Jazeera.

Umer Karim, an associate fellow at the Riyadh-based King Faisal Center for Research and Islamic Studies, said the principal signal Iran was seeking was an end to the US blockade, or at least a clear intent to relax it.

He pointed to Iran’s conduct during the first round. Tehran had initially conditioned its participation on a ceasefire in Lebanon, before entering talks without one.

“That shows they are pragmatic,” Karim told Al Jazeera.

Muhammad Khatibi, a political analyst based in Tehran, said Iran’s position had been consistent throughout, as Iran believes that as long as it cannot export its oil, it will not allow others in the region to do so either.

A tangible easing of the blockade, he said, did not need to be publicly announced, as it could take the form of reciprocal steps, “such as the US permitting a number of Iranian oil shipments to proceed, with Tehran responding in kind”.

“Iran does not seek to re-engage in renewed conflict,” he told Al Jazeera. “But from Tehran’s perspective, this is a war of survival, and it is prepared to fight with all available means until the very end.”

The IRGC factor

The statements from Tehran also reflect a domestic political dynamic underpinning Iran’s public posture, said analysts.

The Islamic Revolutionary Guard Corps (IRGC) has been pushing Iran’s negotiating team to adopt a firmer line, they said, conditioning any return to talks on a full end to the US naval blockade.

Heiran-Nia said the divide between the IRGC and the diplomatic team was evident. He cited instances over the weekend when ships attempting to pass through the strait were allegedly fired on by Iran. India summoned Iran’s ambassador in New Delhi to raise concerns about firing on two of its ships.

“The attack on tankers during the ceasefire demonstrates the IRGC’s dominance over the diplomatic team and its disregard for their positions,” he told Al Jazeera.

Yet Heiran-Nia said if a deal were reached, it would likely override internal opposition.

“If a deal is reached, it will likely have a sovereign character,” he said. “The establishment will impose its own narrative, and the IRGC will accept it.”

What Pakistan is working with

Trump has set firm public red lines. He has demanded Iran end uranium enrichment and surrender its existing stockpile of enriched uranium. He has said the US will not lift the Hormuz blockade until Tehran agrees to negotiate.

“They’re going to negotiate, and if they don’t, they’re going to see problems like they’ve never seen before,” he said in an interview on Monday.

The enrichment question remains the central fault line. During the first round of talks, US negotiators proposed a 20-year pause on Iranian enrichment. Iran countered with five years. Trump has publicly said he wants no enrichment and has refused to set a timeframe for this moratorium.

For Iran, Karim said, the Strait of Hormuz is not simply a bargaining chip.

Tehran is seeking to extract maximum advantage from that leverage before any deal is concluded, he said, because once an agreement is reached, “those cards could no longer be played”.

“Iran understands that it still has leverage,” Karim added, “and that it needs to be utilised to the maximum level in any negotiations.”

Heiran-Nia said Washington’s position on Hormuz was equally entrenched.

“The US wants to remove the Strait of Hormuz card from Iran’s hand,” he said. “Iran, on the other hand, wants not only to preserve it as a negotiating card but also to maintain it as a strategic asset.”

Trump’s messaging problem

Complicating Pakistan’s efforts is Trump’s public messaging around the talks.

His posts on Truth Social and remarks to reporters, in which he claimed Iran had agreed to provisions that sources said had not been finalised, including the handover of enriched uranium, caused visible strain in diplomatic efforts during the first round.

Iranian officials publicly rejected the assertions, while US media reported that some Trump administration officials privately acknowledged his comments had been detrimental, given Tehran’s deep mistrust of Washington.

Karim, however, said Trump’s messaging was “more a form of posturing than a structural obstacle to the talks”.

Heiran-Nia said how Islamabad frames the process will be critical, regardless of the outcome.

“Pakistan is the only actor that has military and security ties with both Washington and Tehran,” he said, adding that its role in shaping the narrative around any agreement, allowing both sides to claim success, would be “of critical importance”.

What comes next

A second round of talks, if they take place, is expected to begin on Wednesday.

Trump has extended the original deadline by 24 hours, saying the truce now ends “Wednesday evening Washington time”, which would be early morning Thursday in Islamabad, and described a further extension as “highly unlikely”. It was initially supposed to end on Tuesday evening in the US, or Wednesday morning in the Middle East.

Whether Iran’s delegation attends remains the central question.

State broadcaster Islamic Republic of Iran Broadcasting said on Tuesday that no Iranian diplomatic delegation, “be it a primary or secondary team, or an initial or follow-up mission”, had travelled to Islamabad.

An Iranian source, however, said there were strong indications that a delegation would still travel to Pakistan, adding that security considerations remained central to any decision.

Heiran-Nia said the consequences of failure in the planned talks would be stark.

“The alternative, return to war, while unable to establish any sustainable balance, promises devastating destruction,” he said.
