美国官员在前往巴基斯坦参加本周末的高风险会谈前表示，若要宣布会谈取得成功，需要在多个关键领域取得进展。
据知情人士透露，经过数小时持续至凌晨的谈判，美国和伊朗谈判团队在其中几个关键议题上陷入僵局。
对美国而言，伊朗拒绝开放霍尔木兹海峡以及放弃其高浓缩铀库存是不可妥协的红线。
若这些问题得不到解决，伊朗提出的解除美国制裁并解冻数十亿美元冻结资产的要求也陷入死局，导致双方均称这场马拉松式会谈以失败告终。
“我们已经明确表明了我们的红线，哪些事情我们愿意做出让步，哪些事情我们不会妥协，”副总统J·D·万斯在离开他待了18小时的豪华酒店、返回飞机并飞回国前说道。
他未提及后续行动，美国官员表示，他们将等待唐纳德·特朗普总统就当前战争的未来发出信号，因为谈判似乎陷入停滞。目前尚不清楚特朗普是否会在上周实施的为期两周的停火协议到期前允许开展更多轮外交磋商。
但特朗普周日上午在社交媒体上发文时，并未明确说明战争是否会重启。
“我本可以详细阐述，谈谈我们已经取得的诸多成果，但只有一件事至关重要——伊朗不愿放弃其核野心！”他写道。“在很多方面，双方达成的协议要点都比我们继续军事行动直至结束要好，但与让如此反复无常、难以捉摸、不可预测的国家掌握核力量相比，所有这些要点都毫无意义。”
他表示美国将开始动用本国海军在海峡巡逻，并誓言任何抵抗的伊朗船只都将被“炸成灰烬”。但目前尚不清楚特朗普是否会在上周实施的为期两周的停火协议到期前允许开展更多轮外交磋商。
一名美国官员透露，包括特使史蒂夫·威特科夫和贾里德·库什纳在内的美国谈判代表均未留在巴基斯坦伊斯兰堡恢复会谈，随美国代表团一同前往的技术专家也已撤离。
特朗普声称其团队与伊朗谈判代表建立了“非常友好和相互尊重”的关系。但他表示，人际联系并无多大意义，“因为他们在最重要的问题上极为强硬，而且正如我从一开始就一直说的那样，多年来一直如此——伊朗永远不会拥有核武器！”
一些官员指出，谈判风格的根本差异也是导致僵局的一个因素。伊朗过去曾愿意接受复杂漫长的谈判以达成协议。奥巴马时代的核协议谈判耗时约两年。
特朗普似乎并不愿意进行旷日持久的谈判。
但目前也不清楚总统是否愿意重启一场在美国民众中越来越不受欢迎的战争，而他声称美国已经赢得了这场战争。
伊朗方面的主要抵抗领域——其核计划和海峡问题——各自给美国带来了独特的挑战。
核分歧与战争爆发前相比并无变化。正是伊朗拒绝放弃铀浓缩活动并交出埋藏在地下的400公斤接近武器级的铀，导致此前由威特科夫牵头的一轮谈判陷入停滞。
官员们表示，双方在会谈期间都提出了解决核问题的方案。特朗普此前曾声称美国和伊朗将共同消除他所谓的“核尘埃”，但伊朗似乎并未为之所动。
目前尚不清楚美国此前提出的一项提案是否仍在谈判桌上：美国向伊朗提供十年期核燃料，以换取伊朗停止所有铀浓缩活动。
霍尔木兹海峡是一个新出现的问题。伊朗在之前的谈判中曾保持海峡畅通，仅在美国和以色列发动打击后才切断了油轮通航。如今，海峡封锁造成全球能源市场动荡，并让特朗普在国内面临政治压力。
特朗普要求伊朗立即重新开放这条航道，并威胁若伊朗不从命——甚至在万斯飞往巴基斯坦参加会谈之前就发出了威胁。但官员们表示，伊朗谈判代表意识到海峡封锁为他们带来了筹码，因此拒绝在最终协议达成前让步。
Deadlock on Strait of Hormuz and Iran’s nuclear stockpile led to impasse, officials say

Entering this weekend’s high-stakes talks in Pakistan, US officials identified a number of key areas where they would need to see progress in order to declare success.
After hours of talks stretching into the early morning, US and Iranian negotiating teams had reached an impasse on several of those critical points, according to people familiar with the discussions.
For the US, Tehran’s refusal to reopen the Strait of Hormuz and give up its stockpile of highly enriched uranium were nonstarters.
Without those issues resolved, Iran’s demands that the US lift sanctions and unfreeze billions of dollars in frozen assets also met a dead end, causing both sides to declare the marathon talks a bust.
“We’ve made very clear what our red lines are, what things we’re willing to accommodate them on, and what things we’re not willing to accommodate them on,” Vice President JD Vance said before leaving the luxury hotel where he’d spent the last 18 hours, returning to his airplane and flying home.
He did not say what would happen next, and US officials said they would wait to see what President Donald Trump signals about the future of the war now that negotiations appear stalled. It wasn’t clear whether Trump would allow more rounds of diplomacy before the two-week ceasefire put into place last week expires.
But writing on social media Sunday morning, Trump offered little clarity on whether the war would restart.
“I could go into great detail, and talk about much that has been gotten but, there is only one thing that matters — IRAN IS UNWILLING TO GIVE UP ITS NUCLEAR AMBITIONS!” he wrote. “In many ways, the points that were agreed to are better than us continuing our Military Operations to conclusion, but all of those points don’t matter compared to allowing Nuclear Power to be in the hands of such volatile, difficult, unpredictable people.”
He said the US would begin using its own navy to patrol the strait, vowing any Iranian ship that resists would be “BLOWN TO HELL.” But it wasn’t clear whether Trump would allow more rounds of diplomacy before the two week ceasefire put into place last week expires.
None of the American negotiators, including envoys Steve Witkoff and Jared Kushner, stayed behind in Islamabad, Pakistan to resume the conversations, a US official said. The technical experts who accompanied the American delegation also departed.
Trump claimed his team had developed “very friendly and respectful” relations with their Iranian interlocutors. But he said the interpersonal ties mattered little “because they were very unyielding as to the single most important issue and, as I have always said, right from the beginning, and many years ago, IRAN WILL NEVER HAVE A NUCLEAR WEAPON!”
Some officials pointed to a fundamental difference in negotiating styles as an element in the deadlock. Iran has been willing in the past to submit to complex, winding talks to strike a deal. The process to reach the Obama-era nuclear agreement took roughly two years.
Trump’s desire for prolonged negotiations seems minimal.
But it’s also not clear the president has much appetite for resuming a war that has become unpopular among Americans, and which he claims the US has already won.
The main areas of Iranian resistance — its nuclear program and the strait — each present unique challenges for the United States.
The nuclear disagreement appears unchanged from before the war began. It was Iran’s refusal to give up enrichment and hand over the 400 kilograms of near-bomb grade uranium buried underground that caused an earlier round of negotiations, led by Witkoff, to stall.
Both sides presented offers meant to resolve the nuclear issue during the talks, officials said. Trump has previously claimed the US and Iran would work together to remove what he calls the “nuclear dust,” though Iran appeared unmoved.
It wasn’t clear whether a previous proposal, where the US would provide Iran with nuclear fuel for a decade in exchange for Iran halting all enrichment, was still on the table.
The Strait of Hormuz presents a newer problem. Iran kept the channel open during earlier talks, only choking off tanker traffic after the US and Israel launched strikes. Now, the closure is causing turmoil in global energy markets and political pain for Trump at home.
Trump has demanded Iran immediately reopen the waterway and issued threats if they did not – even as Vance was flying toward Pakistan for the talks. But Iranian negotiators, aware the leverage the strait is providing them, refused to submit until a final deal was reached, officials said.
