US President Donald Trump has repeatedly mentioned 'nuclear dust' in discussions about the conflict with Iran, a term he uses to describe Iran's stockpile of highly enriched uranium. This uranium, enriched to approximately 60% purity, is seen as dangerously close to the 90% purity needed for nuclear weapons. Although not a weapon itself, it exists in a precarious grey zone, making it a focal point in the ongoing tensions. Experts have criticized the term for oversimplifying a complex issue, as this uranium is typically stored as a gas in specialized containers rather than as loose powder. Much of it is believed to be located at key nuclear sites in Iran, some of which have been targeted by US strikes. There are concerns about the material's current status, with indications that it may be buried under rubble. Trump has suggested that securing this uranium could be crucial for resolving the conflict, claiming that Iran had agreed to hand it over. However, Iranian officials have denied any such agreement, and experts highlight that extracting the uranium amid ongoing hostilities would be technically challenging and fraught with risks.
