Trump says he has “had enough” of Iran conflict in the Middle East

Less than 24 hours after warning that an entire civilisation could be destroyed before sunrise, Donald Trump was celebrating world peace.

The extraordinary whiplash that played out across social media and the world's news wires on Wednesday marked what may be the most volatile stretch of presidential communication in modern American history.

And it ended, for now, with a two-week ceasefire between the United States and Iran, and the Strait of Hormuz re-opened to global shipping.

"A big day for World Peace!" the US President declared on his Truth Social platform.

Trump added that Iran had "had enough" of conflict and predicted a "Golden Age of the Middle East."

It was a striking departure from the tone he had struck just hours earlier, when he posted a profanity-laced ultimatum to Tehran demanding the Strait be opened immediately or face annihilation.

"A whole civilisation will die tonight, never to be brought back again," Mr Trump wrote as his self-imposed deadline approached with no deal in sight.

The ceasefire was struck with just over an hour to spare.

Pakistan played a pivotal behind-the-scenes role, with Mr Trump crediting Prime Minister Shehbaz Sharif and Field Marshal Asim Munir for urging him to hold back the military force he said was already positioned and ready to strike.

Pentagon allies had publicly backed that claim.

Under the 10-point framework agreed to by both sides, the Strait of Hormuz — the narrow chokepoint through which roughly a fifth of the world's oil supply passes, would re-open under new conditions.

Iran's security council indicated Tehran would collect fees for use of the waterway, sharing revenue arrangements with Oman, on the other end of the passage.

What remains unclear is whether the United States has agreed to pay those fees.

Mr Trump was bullish about what comes next, pledging American involvement in Iran's reconstruction and describing a future of investment and goodwill.

"Big money will be made. Iran can start the reconstruction process," Trump wrote.

He added that the US would be "loading up with supplies of all kinds" and sticking around the region to ensure stability, including helping manage what he described as a traffic build-up in the Strait.

The agreement has bought negotiators a fortnight to finalise what Mr Trump described as a longer-term peace framework. The President claimed that almost all major points of contention had already been resolved between the two nations.

Ceasefire agreements in the Middle East have a fraught history, and analysts have noted the deal remains fragile — contingent on goodwill from both sides.

For now, oil is flowing, military strikes have been suspended, and a US President who threatened to reduce a nation to rubble is talking about golden ages and reconstruction funds.
