US and Iran Fail to Reach Deal in Marathon Talks Since 1979, as US Demands Iran Commit to Nuclear Non-Proliferation

US and Iran failed to reach a deal after marathon talks in Islamabad, marking the highest-level dialogue between the two nations since the 1979 Islamic revolution. Vice President JD Vance, leading the American delegation, declared that Iran refused to accept US terms, calling the lack of agreement "bad news for Iran much more than it's bad news for the United States." The 21-hour negotiations, held in Pakistan's capital, ended without resolution, leaving both sides to issue starkly different interpretations of the outcome. Vance emphasized that the US demands a "fundamental commitment" from Tehran to forgo nuclear weapons, including a pledge not to pursue the tools that could enable rapid weaponization. "We need to see an affirmative commitment," he said, underscoring the US stance that Iran must not only halt nuclear development but also eliminate pathways to achieve it.

Al Jazeera's John Hendren noted the significance of Trump sending Vance to the talks, highlighting the administration's seriousness about engaging with Iran despite the fraught history. He suggested the failure to agree might not signal the end of negotiations, pointing to unresolved issues like Iran's control of the Strait of Hormuz and gaps in nuclear assurances. "The US has been negotiating with Iran over time; those talks can continue remotely," Hendren said, adding that the current impasse reflects the complexity of addressing both nuclear and regional security concerns simultaneously. The US has long sought to prevent Iran from acquiring nuclear capabilities, but the latest round of talks revealed deep mistrust, with Tehran insisting on broader security guarantees and economic concessions before agreeing to any restrictions.

Iran's Foreign Ministry dismissed expectations of a breakthrough in a single session, with spokesperson Esmaeil Baghaei stating, "Naturally, from the beginning, we should not have expected to reach an agreement in a single session." The Iranian delegation emphasized confidence that dialogue with Pakistan and regional allies would continue, though it offered no specifics on the contentious issues discussed. Al Jazeera's Tohid Asadi reported that the talks this time addressed a "comprehensive approach," expanding beyond the nuclear dossier to include control of the Strait of Hormuz, war reparations, and a regional ceasefire. Tehran's demands, however, face resistance from US allies like Israel, which has refused to halt its military campaign against Hezbollah in Lebanon. The ceasefire deal announced by Pakistani Prime Minister Shahbaz Sharif, which included Lebanon, was rejected by both the US and Israel, complicating efforts to address regional tensions.

As the talks concluded, Israeli Prime Minister Benjamin Netanyahu reiterated Israel's commitment to confronting Iran and its proxies. "Israel under my leadership will continue to fight Iran's terror regime and its proxies," he said on X, signaling no immediate intent to ease hostilities. Netanyahu also mentioned ongoing efforts to broker a deal with Lebanon, though progress remains unclear. Meanwhile, Iran's state media highlighted its insistence on a ceasefire across the region, including in Lebanon, but the lack of consensus on this front has left the talks in limbo. The failure to reach an agreement underscores the deep divides between the US and Iran, with neither side willing to make concessions that could be perceived as capitulation. As the geopolitical stakes rise, the next steps—whether through renewed negotiations or escalation—remain uncertain, but one thing is clear: the path to reconciliation is far from straightforward.

Israel will not accept a ceasefire with Hezbollah," declared Yechiel Leiter, Israel's ambassador to the United States, after an unprecedented meeting with Lebanon's envoy in Washington, DC. The encounter, marked by tense exchanges, underscored the deepening rift between Tel Aviv and Beirut as violence in southern Lebanon escalates. Leiter's statement came amid renewed Israeli airstrikes that left six dead in Tyre, a city already scarred by weeks of relentless bombardment. "The only path forward is total disarmament of Hezbollah," he insisted, his voice firm as he addressed reporters in the embassy's marble-floored hall.

Meanwhile, Pakistan's Foreign Minister Ishaq Dar urged the US and Iran to "continue with a positive spirit" to achieve peace. Speaking from Islamabad, Dar praised both nations for recognizing Pakistan's role as a mediator but warned that "ultimatums and mistrust will not bridge divides." His remarks followed reports that the US is demanding Iran abandon all nuclear programs, including those for medical purposes—a stance Iran has rejected in talks mediated by Oman. "The US is asking Iran to give up its right to any nuclear programme, even for medical purposes," Al Jazeera's Osama Bin Javaid noted from Islamabad. "This is a sea of mistrust they're trying to build bridges over."

The war that erupted on February 28 between the US-Israeli coalition and Iran has left more than 2,000 dead and vast swaths of the Middle East in ruins. Tehran's retaliatory strikes on Israel and Gulf nations hosting US military assets have turned the region into a cauldron of destruction. Experts warn that the conflict violates international law, with its roots tracing back to the 2015 nuclear deal scrapped during Trump's first term. That agreement, which curbed Iran's nuclear ambitions in exchange for sanctions relief, was undone by Trump's insistence on "maximum pressure," a policy that left Iran isolated and emboldened.

Now, as the war grinds on, the Strait of Hormuz has become a flashpoint. Iran's blockade of the waterway, through which 20% of global oil and gas exports pass, has triggered a new energy crisis. Tankers sit idle in the Gulf, their crews stranded as shipping routes grow perilous. "This isn't just about politics," said one Gulf analyst in Dubai. "It's about survival—for nations, economies, and millions of people who depend on these lifelines."

Back at the negotiating table, US envoy Jake Sullivan and Iranian Parliament Speaker Mohammad Bagher Ghalibaf have clashed over ceasefire terms. Israel's continued attacks on Hezbollah, however, threaten to derail any progress. "The talks are already fragile," said a Western diplomat in Geneva. "Without a pause in violence, there's no hope for a deal." As the region teeters on the edge of further chaos, one truth remains: the war's legacy will be measured not in treaties signed, but in lives lost and futures shattered.
