Trump Sends Letter to Iran's Supreme Leader Seeking New Nuclear Deal, Warns of Military Action

President Donald Trump has sent a letter to Iran's Supreme Leader Ali Khamenei seeking negotiations for a new nuclear deal, while simultaneously warning of potential military action if diplomatic efforts fail [1][2].
The letter, sent on Thursday, March 6, 2025, aims to replace the 2015 nuclear agreement that Trump withdrew from during his first term. Iran's UN mission in New York has stated they have not received any letter [1].
Speaking to Fox Business News, Trump revealed: 'I've written them a letter saying, 'I hope you're going to negotiate because if we have to go in militarily, it's going to be a terrible thing'' [1].
The diplomatic outreach comes amid concerning developments in Iran's nuclear program. According to recent UN nuclear watchdog reports, Iran has significantly expanded its uranium stockpile to 8,294.4 kilograms, with some enriched to 60% purity - far exceeding the 2015 deal's limits of 300 kilograms at 3.67% purity [3].
U.S. intelligence agencies assess that while Iran has not begun a weapons program, it has 'undertaken activities that better position it to produce a nuclear device' [4].
The response from Tehran remains uncertain. While Iran's reformist President Masoud Pezeshkian campaigned on Western outreach, Supreme Leader Khamenei recently stated negotiations with America 'are not intelligent, wise or honorable' [1]. Khamenei previously rejected Trump's 2019 attempt at communication through then-Japanese Prime Minister Shinzo Abe [5].
The diplomatic initiative unfolds against a backdrop of regional tensions, including direct exchanges between Iran and Israel during the ongoing Israel-Hamas conflict, and Iran's deteriorating economic conditions under continued sanctions [3].
