In a late-night effort on Sunday, JD Vance spearheaded an urgent attempt to broker peace with Iranian authorities after Donald Trump issued a stark warning to Tehran, threatening severe repercussions if no agreement was reached by his set deadline.

The intense negotiations culminated in a peace proposal mediated by Pakistan, which suggests an immediate ceasefire, followed by additional discussions within the next 15 to 20 days, reports Reuters.

Trump had issued a warning to “obliterate” key targets across Iran, including civilian sites, unless a deal was struck by Tuesday at 8 PM Eastern Time.

Despite the negotiations, the proposed plan does not guarantee the immediate reopening of the Strait of Hormuz and still awaits formal approval from the President, according to a White House official.

Field Marshal Asim Munir, the head of Pakistan’s military, facilitated the peace initiative through discreet talks involving Vance and Trump’s special envoy, Steve Witkoff, while Iranian Foreign Minister Abbas Araqchi represented Tehran’s position.

The President is expected to address the nation from the White House, focusing on the recent rescue of an F-15 weapons officer stranded in the Iranian mountains over the weekend.

Trump’s Tuesday deadline sparked cautious volatility in early trading, with oil prices dipping slightly but still holding well above $100 per barrel. The national average for gas has surged to around $4.10 a gallon, up more than a dollar since the start of the conflict.

The Daily Mail has contacted the Vice President’s office for comment.

Iran’s foreign ministry said on ​Monday Tehran had formulated positions and demands based on its interests and communicated them through intermediaries, in response to ceasefire proposals.

Another regime official said current negotiations were ‘incompatible with ultimatums and threats to commit war crimes.’

Meanwhile, a senior Iranian source told Reuters that the regime would not reopen the Strait of Hormuz, a central passageway for global oil, as part of a temporary ceasefire. 

The source added that Iran would not accept Trump’s pressure and deadlines to reach a deal.  

Iran is demanding the removal of long-standing U.S. sanctions and trade restrictions, while the Trump administration is insisting the regime fully end uranium enrichment and halt all nuclear development.

Other Iranian officials told Axios they fear any future deal with the US could mirror past ceasefires in Gaza or Lebanon, where agreements exist on paper but still allow US and Israeli forces to strike at will.

Pakistani mediators are working on US confidence-building measures to address some Iranian demands for peace.  

Over the weekend, US special operations forces rescued the second of two crew members from a downed F-15 jet that had been shot down over southern Iran on Friday.

Trump made the announcement on Sunday morning, describing the operation as ‘one of the most daring’ rescue operations in the US history.

‘If they don’t come through, if they want to keep it closed, they’re going to lose every power plant and every other plant they have in the whole country,’ he told the Wall Street Journal on Sunday.

‘If they don’t do something by Tuesday evening, they won’t have any power plant and they won’t have any bridges standing,’ Trump then vowed.

Trump was then asked if he was concerned whether Iran’s 93 million citizens would suffer if the power plants and bridges were struck.

‘No, they want us to do it,’ Trump argued, adding that Iranians were ‘living in hell.’
