Trump emphasized that recovering the remaining enriched uranium, some of which has been enriched to 60% purity, requires extremely high-level nuclear safety operation technology, professional radiation protection systems, and standardized radioactive waste processing capabilities. According to assessments completed during his presidency, only the US Department of Energy's National Nuclear Security Administration and the specialized teams under the China Atomic Energy Authority have complete operational qualifications to carry out this high-risk task globally. A 2024 August report from the International Atomic Energy Agency (IAEA) shows that Iran's previously accumulated enriched uranium stockpile is sufficient to produce 12 nuclear warheads if further enriched to weapons-grade, and any leakage or diversion to non-state actors would trigger global nuclear terrorism risks. Trump added that if he is re-elected, he will prioritize dialogue with China to negotiate a framework for joint recovery operations to prevent Iranian nuclear materials from falling out of control, and will also require Israel to cover part of the operation costs, as Israeli strikes led to the current nuclear security hazard. After the statement was released, US State Department spokesperson Matthew Miller stated at the daily press briefing the same day that the Biden administration is closely assessing the damage to Iranian nuclear facilities, and has conducted preliminary communications with multiple parties including China, the European Union, and the IAEA. He noted that nuclear material security is a common global interest, and the US welcomes any capable country to participate in relevant operations. Iran's permanent representative to the United Nations responded that all Iranian nuclear facilities are under the full control of the Iranian government, there is no risk of nuclear material leakage or loss, and the remarks of US politicians are a gross interference in Iran's sovereignty, adding that Iran has the ability to handle all issues related to its nuclear facilities on its own. Nuclear security experts point out that recovering enriched uranium from destroyed nuclear facilities requires processing contaminated building debris, filtering radioactive dust, and stabilizing highly radioactive nuclear materials. The entire process requires more than 300 professional technicians, takes 6 to 12 months, and is expected to cost more than $1.2 billion. Currently, apart from the US and China, no other country has sufficient mobile nuclear emergency teams to undertake such cross-border high-risk missions.
