A final nuclear agreement between the United States and Iran hinges on the physical transfer of the country’s enriched uranium stockpile to international custody. According to a senior U.S. official, Washington maintains that securing this material is a mandatory requirement for any deal, warning that if Iran refuses, the U.S. will rely on continued military, economic, and diplomatic pressure to limit the program.
The Dispute Over Enriched Uranium Stockpiles
The U.S. demand for the removal of enriched uranium stands as a primary obstacle in ongoing negotiations. A senior American official stated on May 10 that “if we don’t get the material, we won’t have a deal with Iran.”

However, the strategy regarding this material has faced internal discrepancies. President Donald Trump previously downplayed the necessity of removing the uranium during a NATO summit in Turkey. Trump argued that the material is already effectively neutralized, stating, “We already have the nuclear material, because it’s way below the surface.” He added that “nobody will be able to get it, except us.”
IAEA Oversight and the Memorandum of Understanding
While the demand for the removal of the stockpile remains a flashpoint, current diplomatic efforts include a memorandum of understanding (MOU) between the two nations. This framework outlines a “minimum methodology” for Iran to reduce the concentration of its enriched uranium. Under the terms of the MOU, this process would occur on-site while under the direct supervision of the International Atomic Energy Agency (IAEA).
Although the MOU includes a formal reaffirmation from Tehran that it will not acquire or develop nuclear weapons, specific technical details regarding enrichment limits and nuclear transparency remain subject to further negotiation. These finer points are expected to be the focus of discussions leading toward a comprehensive final agreement.
Future Pressures and Diplomatic Options
Should negotiations stall or Iran refuse to relinquish its stockpile, U.S. officials have signaled that the status quo will be met with active containment measures. The senior official clarified that the U.S. has “many options if they resist handing over the material.” These options include maintaining existing economic sanctions, continuing diplomatic isolation, and keeping military pressure as a viable deterrent.

The tension between the goal of total material removal and the reality of on-site processing under IAEA supervision continues to define the strategic landscape of the talks.
Frequently Asked Questions
- Why does the U.S. want Iran to hand over its uranium?
The U.S. government views the physical removal of enriched uranium as a necessary step to ensure that Iran cannot use the material to develop nuclear weapons. - What is the alternative to removing the uranium?
The MOU proposes a “minimum methodology” where Iran reduces the concentration of its uranium on-site, provided it remains under the supervision of the IAEA. - What happens if Iran refuses the U.S. demands?
A senior U.S. official stated that the U.S. would respond with continued military, economic, and diplomatic pressure. - Has the U.S. position on the uranium stockpile been consistent?
No. While administration officials have emphasized the need to secure the material, President Trump has previously suggested that the location of the material—deep underground—makes it inaccessible to others, effectively neutralizing it.
