On Tuesday, President Donald Trump issued a fresh ultimatum to Iran, giving them a "two or three-day" window to agree to a nuclear deal. His statement, made from the White House, ramps up the diplomatic pressure on Tehran amid what the president describes as a "remarkably fragile" ceasefire.
"I'm saying two or three days. Maybe by Friday, Saturday, or Sunday. Perhaps early next week. It's a limited timeframe," Trump stated, according to EFE news agency.
This ultimatum comes a day after Trump halted a planned strike on Iran, citing "serious negotiations underway," as reported by CBS News.
The Standoff Over Nuclear Terms
The divide between both nations remains vast. The United States demands the complete dismantling of Iran's nuclear program, a 20-year halt on uranium enrichment, and the transfer of 440 kilograms of uranium enriched to 60%.
Conversely, Iran proposed a three-phase plan with a 15-year pause on enrichment, which Trump dismissed on May 11 as "totally unacceptable."
Furthermore, Tehran insists they will not discuss nuclear details while armed conflict continues, asserting their right to enrichment as recognized under the Nuclear Non-Proliferation Treaty.
Rising Military Tensions
The International Atomic Energy Agency confirmed in March 2026 that Iran had amassed 5,500 kilograms of uranium enriched to 60%, enough to produce several nuclear weapons if further processed.
The military backdrop is equally tense. The U.S. and Israel launched Operation Epic Fury on February 28, 2026, targeting over 2,000 sites within Iranian territory.
Iran retaliated on April 28 with Operation True Promise 4, deploying over 500 missiles and 2,000 drones against Israel and 27 American bases.
Fragile Ceasefire and Diplomatic Efforts
A shaky ceasefire took effect on April 8, 2026, but Trump warned on May 17 that without an agreement, "there will be nothing left of them."
Secretary of State Marco Rubio defended the administration's stance, asserting that Trump is "the first U.S. president to take concrete action" to prevent Iran from acquiring a nuclear weapon.
After 44 hours of talks, Trump described the negotiations as "very good" and saw a "very possible" understanding, although the gap between Washington's demands and Tehran's conditions remains the main hurdle to reaching any deal before the White House's deadline expires.
