The Context of the US’s Nuclear Concerns and Iran’s Position
The United States has long sought to prevent Iran from acquiring nuclear weapons, a goal that has driven its diplomatic and military strategies. During negotiations with Iranian officials over the past year, the US has emphasized the need to ensure Iran cannot produce nuclear weapons using enriched uranium. This demand was a central justification for the US’s involvement in the 2023 conflict with Israel, despite ongoing talks with Tehran. Iran, however, insists its nuclear program is solely for civilian energy purposes, though it has enriched uranium far beyond the levels required for peaceful use. Iranian officials have expressed openness to reducing enrichment levels in past negotiations but have refused to dismantle their nuclear program entirely, citing national sovereignty as a key principle.
The 2015 Joint Comprehensive Plan of Action (JCPOA) aimed to curb Iran’s nuclear ambitions by limiting uranium enrichment and subjecting the program to inspections. However, President Donald Trump’s decision to withdraw the US from the agreement in 2018 left a power vacuum, prompting renewed tensions. Currently, Iran is believed to hold approximately 440 kilograms of uranium enriched to 60 percent, a level that can be rapidly upgraded to the 90 percent threshold needed for nuclear weapons. This stockpile, if left unchecked, could theoretically yield more than 10 warheads, according to International Atomic Energy Agency (IAEA) chief Rafael Grossi.
Experts warn that the US’s recent consideration of a military operation to seize Iran’s enriched uranium stockpile is fraught with complications. The operation would require overcoming chemical, logistical, and tactical challenges, as well as navigating the complex geopolitical landscape of the region. While the US has not confirmed any plans, the potential for such a move underscores the deepening crisis over Iran’s nuclear capabilities and the risks of escalation.
Logistical and Technical Hurdles of a Ground Operation
A military ground operation to extract Iran’s enriched uranium stockpile would face significant logistical and technical challenges, according to experts. The Isfahan nuclear facility, where half of the suspected stockpile is stored, is over 480 kilometers inland, far from the nearest US naval assets. Transporting troops and heavy equipment, including excavators, through an active warzone would be extremely difficult, given the proximity to Iranian forces and the risk of attacks. Additionally, the tunnels at Isfahan are believed to be buried under rubble following previous US-Israeli airstrikes, complicating access and requiring extensive preparation.
Securing the site would be another major obstacle. Ground forces would need to establish a perimeter around the facility and maintain control over the area while extracting the uranium, a process that could take an unpredictable amount of time. Jason Campbell, a senior fellow at the Middle East Institute, described the operation as “risky and not feasible” due to the constant threat of Iranian fire. He noted that senior military officials would likely avoid such a mission given the high stakes and the difficulty of ensuring safety.
The handling of the uranium itself presents further complications. Cheryl Rofer, a former radiochemist at Los Alamos National Laboratory, highlighted that the uranium is likely stored as hexafluoride gas, a substance that reacts violently with water to produce toxic and corrosive chemicals. This requires specialized storage in separate canisters to prevent radiation leaks, adding another layer of complexity to the operation. Francois Diaz-Maurin, an editor for nuclear affairs at the Bulletin of the Atomic Scientists, warned that any damage to the canisters during transport or an air strike could release harmful chemicals, creating a radiological hazard for personnel.
Alternatives to Military Action and Historical Precedents
Instead of pursuing a high-risk military operation, experts suggest that the US could explore diplomatic solutions to address Iran’s nuclear program. A negotiated deal could allow Iran to retain its stockpile under international supervision, reduce enrichment levels, or transfer the material to a neutral location with Iran’s consent. Ian Lesser, a distinguished fellow at the German Marshall Fund of the United States, emphasized that such an approach would avoid the dangers of a military strike and reduce the likelihood of further escalation. He noted that the US and Israel’s initial attacks in February 2023 were part of an effort to negotiate, underscoring the importance of dialogue over confrontation.
Historical precedents, such as the 1994 Project Sapphire operation, offer a model for safely removing nuclear materials. In that secret mission, US forces transported 600 kilograms of weapons-grade uranium from Kazakhstan to the US, working in coordination with Kazakh authorities and the IAEA. The operation required intense coordination, with teams working 12-hour shifts for weeks to move the material covertly. While the IAEA is currently considering a similar approach for Iran, Rafael Grossi cautioned that any such effort would be impossible while the region remains in conflict.
Experts agree that a military operation to seize Iran’s enriched uranium stockpile is not a viable option due to the immense risks involved. Destroying the stockpile, for example, could lead to chemical contamination and environmental hazards, as well as the risk of Iran retrieving enough material to resume its nuclear program. The complexity of such an operation, combined with the potential for unintended consequences, highlights the need for a diplomatic solution. As Lesser concluded, the US must prioritize securing a deal to prevent further escalation and avoid the dangers of a dangerous and uncertain military endeavor.
