Us,Iran most anticipated diplomatic negotiation on Iran nuclear deal has ended in failure. After 21 gruelling hours of face-to-face negotiations in Islamabad, Pakistan the first direct talks between the United States and Iran since 1979 at this level in which Vice President JD Vance boarded Air Force Two and left without a deal. The two-week ceasefire that Pakistan brokered just days ago is now hanging by a huge fear. The Strait of Hormuz remains under Iranian control. And the war that began on February 28 could be about to enter it's most dangerous phase yet. Vance's parting words were blunt and ominous the US has made it's "final and best offer." The next move belongs to Iran.
The talks began on Saturday morning at the Serena Hotel in Islamabad's Red Zone the heavily fortified diplomatic district of Pakistan's capital that houses key government buildings and embassies. The entire hotel had been reserved from Wednesday through Sunday. Pakistan's security presence was intensified across the city. Pavements were freshly painted. The world was watching.
The American delegation was led by Vice President JD Vance, joined by special envoy Steve Witkoff, Jared Kushner the president's son-in-law — Deputy National Security Advisor Andrew Baker and other senior officials. The Iranian delegation was led by Parliament Speaker Mohammad Bagher Qalibaf. They arrived dressed in black in mourning for Supreme Leader Ali Khamenei and others killed in the war. They carried shoes and bags belonging to students killed when a US bomb struck a school near a military compound. It was a powerful statement of where Iran stood before a single word of negotiation had been exchanged.
The talks lasted through Saturday and into the early hours of Sunday morning 21 hours in total. Multiple rounds were held in different formats. Vance said he and his team were in constant communication with President Trump throughout, speaking with him at least half a dozen times. They also consulted with Secretary of State Marco Rubio, Defense Secretary Pete Hegseth, Treasury Secretary Scott Bessent and CENTCOM commander Admiral Brad Cooper. The full weight of the US national security apparatus was engaged in real time, and yet when the sun came up on Sunday, Vance walked out with no agreement reached.
Vance's words in a press conference in Islamabad, his statement was brief and devastating. "We have been at it now for 21 hours, and we've had a number of substantive discussions with the Iranians. That's the good news," he said. "The bad news is that we haven't reached an agreement. And I think that's bad news for Iran much more than it's for US."
He identified the core sticking point with precision Iran's refusal to commit to giving up nuclear weapons. "The simple fact is that we need to see an affirmative commitment that they will not seek a nuclear weapon, and they will not seek the tools that would enable them to quickly achieve one," Vance said. He insisted the US had been "quite flexible" and "quite accommodating" in it's approach. "The US president Donald told us, 'You need to come here in good faith and make your best effort to get a deal.' We did as he said but unfortunately, we weren't able to make any headway."
His closing statement was carefully constructed leaving a door open while making it clear that US had reached it's limit. "We leave here with a very simple proposal a method of understanding that is our final and best offer. We'll see if the Iranians accept it." He didn't say what would happen if Iran rejected the offer. He didn't announce a resumption of bombing. But the phrase "final and best offer" in diplomatic language has a clear meaning take it or leave it no more option than this and we will not be coming back to negotiate any further.
Iran's Foreign Ministry spokesperson Esmaeil Baqaei offered a different framing of the same outcome in the past 24 hours of the negotiation, discussions were held on various dimensions of the main topics, including the Strait of Hormuz, the nuclear issue, war reparations, lifting of sanctions, and the complete end to the war against Iran and in the region," he said, noting that some areas of agreement had been reached while there remained "a gap in viewpoints" on two or three key issues.
Baqaei pushed back on the suggestion that the talks had been a failure. "Naturally from the beginning, we should not have expected to reach an agreement in a single session. No one had such an expectation." Iran's state media went further saying the US was "looking for an excuse to leave the talks" and that "the ball is in America's court." Iranian media characterised the US demands as "excessive" and said those demands had "prevented a common framework and agreement."
The gap between the two sides on the nuclear issue was fundamental. Iran's demand to retain enriched uranium stockpiles and its refusal to commit to never pursuing a nuclear weapon was the wall that the talks could not scale through. The US position and stated by Trump himself before Vance flew to Pakistan was simple: "No nuclear weapon, that's 99% percent of the negotiation plan."
In one of the most audacious diplomatic and military moves of the entire war, two US Navy guided-missile destroyers crossed the Strait of Hormuz on Saturday while the peace talks were still happening the first transit of American warships since the war began six weeks ago. Iran's Revolutionary Guard Corps immediately warned that any military vessels attempting to cross the strait would face "a strong response." Iran's state media initially claimed they had forced a US ship to turn back, though those reports were disputed by Pentagon.
The move was simultaneously a show of force and a diplomatic calculation demonstrating that the US wasn't prepared to accept Iranian sovereignty over the strait while negotiations were ongoing it also carried enormous risk. Had Iran fired on those warships while Vance was sitting across the table from Iranian negotiators, the talks would have collapsed instantly and the war would have escalated dramatically.
The failure to reach a deal throws the two-week ceasefire that Pakistan initiated last Tuesday into serious doubt. The ceasefire was always fragile based on Iran agreeing to allow some passage through the Strait of Hormuz and the US agreeing to pause bombing, with two weeks for negotiations to produce a permanent settlement, those negotiations now stalled, the ceasefire's legal and political basis has weakened significantly.
Pakistan's Foreign Minister Ishaq Dar called on both sides to uphold the ceasefire despite the failed talks, characterising the 21-hour session as "intense and constructive" and urging both parties to maintain the "positive spirit" of the engagement. Israel's continued bombardment of Lebanon more than 200 Hezbollah targets struck in the past 24 hours is adding further strain to a ceasefire that was never comprehensive. Iran has consistently demanded that any ceasefire apply to Lebanon, Iraq and Palestine as well as Iran itself. That demand remains unmet.
One of the most confusing aspects of the entire diplomatic process has been the contradiction between Trump's public statements and the serious diplomatic engagement his administration has pursued. On Saturday, as the talks were ongoing in Islamabad, Trump told journalists: "Whether we make a deal or not makes no difference to me" He claimed the US had already defeated Iran militarily. He boasted in his words: "We're sweeping the strait." Hours later his vice president was presenting Iran with America's "final and best offer" suggesting that the deal mattered very much indeed.
Trump's stated goals for the war have also shifted multiple times. He initially described the objectives as destroying Iran's nuclear and military capabilities and potentially achieving regime change in Tehran. None of those goals have been fully achieved. Iran's nuclear facilities have been damaged but not destroyed. Iran's military has absorbed enormous punishment but remains functional. The regime remains in place. And the Strait of Hormuz the most critical strategic leverage point in the entire conflict remains under Iranian control.
With Vance on a plane back to Washington and Iran's delegation also leaving Islamabad, the world is now in a dangerous period of what next? question that no one knows the answer but my thoughts are, three possible scenarios in the coming days.
Firstly the Iran reviews the US "final and best offer," makes some movement on the nuclear commitment question and a new round of talks is scheduled. This would keep the ceasefire alive and the diplomatic process moving the best outcome for global energy markets and regional stability.
Secondly Iran rejects the offer entirely, the ceasefire expires with no extension, and Trump resumes bombing. This was always the risk that the two-week ceasefire was designed to prevent. If this happens, oil prices will spike immediately and the war will enter it's most destructive phase.
Thirdly and perhaps the most likely and the short term this period of ambiguity neither side formally announces a breakdown. The ceasefire holds informally. Back-channel contacts continue through Pakistan. And a second round of talks is arranged for the coming weeks without either side having to publicly back down from their stated positions.
Every oil-dependent economy watching from the sidelines, the failure of the Islamabad talks is deeply concerning. Oil prices had begun to ease after the ceasefire announcement. The prospect of the Strait of Hormuz reopening fully had given global markets hope,but that hope is now significantly dimmer. If the ceasefire collapses and bombing resumes, oil prices will spike again directly hitting Nigerian fuel costs, transport prices and the cost of every imported good in the country.
21 hours. Two delegations. The first direct US-Iran talks since 1979. And Vance leaves empty-handed.
The nuclear question was always going to be the hardest thing. Iran no fit tell it's people say dem give up the one thing wey dey make America and Israel think twice before going further. America no fit go home without something on nuclear otherwise wetin be the point of the whole war?
That deadlock na the story of this entire conflict in one sentence. Both sides need something the other side cannot give without losing face at home. Until that changes, the bombs may fly again. Watch the next 72 hours — that is when we will know whether this ceasefire survives or not.
