Trump Issues Ultimatum to Iran Over Nuclear Deal, Warns of Military Action

President Donald Trump has given Iran a final 10 to 15 days to reach a deal regarding its nuclear program, threatening unspecified but severe consequences if an agreement is not reached. The escalating rhetoric comes amid a significant U.S. Military buildup in the Middle East, raising fears of a potential conflict.

Trump’s Deadline and Potential Action

Speaking at the inaugural meeting of his Board of Peace on February 19, 2026, Trump repeatedly hinted at a willingness to grab action against Iran beyond ongoing peace talks. He stated, “We may have to take it a step further or we may not,” adding, “Maybe we’re going to produce a deal. You’re going to be finding out over the next probably 10 days.” USAToday

During a flight to Georgia later the same day, Trump declined to discuss specific military plans but reaffirmed the 10-15 day timeline for a decision. He emphasized that this was a “maximum” timeframe. USAToday

Iran’s Response and Warnings

Iran responded to Trump’s ultimatum with a letter to the United Nations Secretary-General Antonio Guterres, warning of retaliation against U.S. Bases and assets in the region should military action be taken. The letter, from Iran’s permanent ambassador to the UN, Amir Saeid Iravani, stated that all “bases, facilities, and assets of the hostile force in the region would constitute legitimate targets.” USAToday, The Independent

The Iranian letter also asserted that Iran does not seek tension and would not initiate war, but would respond “decisively and proportionately” to any attack. USAToday
