The figures cited in the claim align closely with official White House records and contemporary reporting from 2015 and 2016. According to archived White House documents, the Iran nuclear deal required Tehran to reduce its uranium stockpile by 98%, keeping only 300 kilograms (roughly 660 pounds) of uranium enriched to 3.67%. Before the deal, Iran held a stockpile of approximately 25,000 pounds of enriched uranium, which was enough to create multiple nuclear bombs.
Reports from The Guardian and Deutsche Welle at the time confirm that on December 28, 2015, a ship carrying more than 25,000 pounds of low-enriched uranium departed Iran for Russia. This shipment represented the bulk of Iran's enriched material. Secretary of State John Kerry described this as a significant step that increased Iran's 'breakout time'—the time needed to produce enough material for a weapon—from two or three months to at least one year.
Recent reporting from 2026 by The New York Times provides additional historical context, noting that while the 2015 deal successfully reduced the stockpile to under 660 pounds, the situation changed significantly after the U.S. withdrawal from the pact in 2018. By 2026, Iran's stockpile had reportedly grown back to 22,000 pounds following years of renewed enrichment. Therefore, while the claim accurately reflects the success of the Obama-era diplomacy at the time it was implemented, it describes a historical status that has since been overtaken by more recent geopolitical developments.
Source quality: The evidence includes archived White House documents, contemporary reporting from The Guardian and DW, and a detailed retrospective from The New York Times. These sources consistently confirm the 97-98% reduction figure and the shipment of 25,000 pounds of uranium.
