Trump and Iran Face Off: Hand Over 400 Kilograms of Enriched Uranium, or the US Military Won't Launch an Attack!
In early 2026, US-Iran relations once again slid to the brink of the cliff. This time, Trump issued a final ultimatum: Iran must hand over 400 kilograms of highly enriched uranium - otherwise, the US military will take military action.
According to internal White House information and Pentagon deployment records, the US Navy has mobilized multiple main warships, including the "Nimitz" aircraft carrier battle group, and gathered near the waters of the Persian Gulf and the Gulf of Oman. This naval force, called by Trump as "the largest and strongest in the world," is within less than 500 nautical miles from the Iranian coastline, capable of conducting precise strikes on multiple nuclear facilities inside Iran within a few hours.
So why 400 kilograms? This number is not arbitrarily set. According to previous reports from the International Atomic Energy Agency (IAEA), Iran has repeatedly approached or briefly exceeded the 300-kilogram limit of low-enriched uranium stipulated by the Joint Comprehensive Plan of Action (JCPoA), also known as the Iran nuclear deal.
The quantity of 400 kilograms is roughly equivalent to the threshold amount required for manufacturing a basic nuclear bomb. Even though Iran currently claims its enrichment level is only 60%, which is not yet weapon-grade (over 90%), once it possesses sufficient stockpiles, it could rapidly cross the critical point through further purification. Therefore, the US demand that Iran hand over this 400 kilograms of enriched uranium essentially aims to completely cut off its technical path for a "nuclear sprint" in the short term.
Since the end of 2025, the Israeli intelligence agency has frequently provided the US with so-called evidence of Iran secretly restarting the Fordow underground nuclear facility. Although these intelligence reports have not been independently verified by the IAEA, they have been sufficient to push Trump to make more radical decisions. A White House official privately revealed that the Trump team's internal assessment believes, "If the Iran nuclear issue is not resolved during his second term, there will be no opportunity in the future."
