US President Donald Trump on Tuesday, 22 September 2026, issued a stark ultimatum to Iran from the floor of the United Nations General Assembly in New York — strike a deal with Washington that enables Iran to become a 'greater country', or face complete annihilation. The warning, delivered during a high-level UNGA session, marks one of Trump's most direct public threats against Tehran since the US military conducted Operation Midnight Hammer.

The Ultimatum in Trump's Own Words

'I have a big decision to make: Will a deal be made with Iran that lets them rebuild and create a far greater country than it ever was before, maybe one of the greatest in the Middle East or even the world? — Or do I annihilate the Islamic Republic and do it quickly,' Trump said before assembled world leaders.

The US President also reiterated his longstanding red line: 'I will never allow Iran to have a nuclear weapon.' He claimed that Operation Midnight Hammer, carried out the previous year, had 'obliterated' Iran's nuclear programme, leaving it 'under mountains of rubble' — though independent verification of that claim was not available at the time of writing.

Iran's Presence at the UN and the Absent Response

Iranian President Masoud Pezeshkian was permitted by Washington to attend the UN proceedings, but it was not confirmed whether he was present in the hall during Trump's address. Earlier, Trump had reportedly offered to hold direct talks with Pezeshkian in New York; as of Tuesday, Tehran had not publicly responded to that offer.

Midterm Elections as the Diplomatic Pivot Point

Trump indicated that a deal could materialise shortly after the upcoming US midterm elections in November. 'Iran's leaders were looking for a possible change in Congress, but that won't make a difference,' he said. 'I believe we'll make a deal right after the election because it doesn't make sense for them not to.' He also pushed back against any notion that Iranian leaders could leverage his electoral ambitions, noting: 'They're waiting to see how I do in the midterm election. What they don't realise is that I'm not running.'

A UNGA Speech That Sounded Like a Campaign Rally

Trump's 38-minute address drew comparisons to a domestic campaign speech rather than a conventional diplomatic statement. The bulk of his remarks covered what he described as domestic achievements — lowering the US poverty rate and securing a deal with Denmark granting the US unlimited military access — alongside criticism of the media and government leakers. The Iran ultimatum, while brief, dominated international headlines.

What Comes Next

The diplomatic window Trump described is narrow but explicit — November's midterms as a potential inflection point. Analysts and regional observers will closely watch whether Tehran signals any openness to negotiations, or whether the rhetoric hardens further. This comes amid broader tensions in the Middle East, where any US–Iran rapprochement — or escalation — carries consequences well beyond the two countries.
