The ongoing concerns regarding Iran’s nuclear capabilities emphasize the complexity of military and diplomatic strategies.
When War Secretary Pete Hegseth faced questions about securing enriched uranium at Iran’s Isfahan nuclear complex, he cited operational security, steering clear of specific answers. This exchange highlights a critical dilemma: Even if U.S. airstrikes degrade Iran’s nuclear infrastructure, a larger question looms—who will ensure the physical security of the potentially dangerous material?
Iran is believed to have a significant quantity of uranium enriched to 60%, which is dangerously close to the threshold for weapons-grade enrichment. While moving from 60% to 90% involves additional processing, the more pressing matter is the physical control of this uranium. Kelsey Davenport, a director at the Arms Control Association, points out that securing the uranium would necessitate a “massive ground operation.” Iran’s current stockpiles are reportedly well-hidden and stored in mobile canisters, suggesting that a simple airstrike won’t suffice.
Davenport raises an alarming possibility: “It’s not even clear the United States knows where all of the uranium is.” The mobility of these canisters complicates the situation further, as it raises the concern that some material may have been moved or dispersed, creating an even greater challenge for U.S. forces.
The administration’s Operation Epic Fury aims to prevent Iran from obtaining nuclear weapons. Hegseth reiterated President Trump’s assertion that the matter needs urgent resolution. However, despite these objectives, there is a distinct gap between significant airstrikes against missile systems and the more nuanced task of managing enriched uranium directly. Experts recognize that while airstrikes can damage infrastructure, they may not eliminate the threat posed by enriched materials stored underground.
Defense officials have acknowledged this disparity. Destroying centrifuges and related infrastructure will not necessarily secure the uranium itself. For instance, strikes could lead to safety risks if storage casks are compromised, potentially releasing harmful chemicals. Chuck DeVore, a former defense official, cautions against direct targeting of the uranium stockpile while emphasizing the risks of radioactive contamination.
DeVore also argues that the urgency of a nuclear breakout is overstated; further enriching uranium and assembling a deliverable weapon would likely be challenging under ongoing military pressure. Nonetheless, he contends that the long-term solutions for securing uranium will demand a political resolution within Iran and some level of external oversight.
Securing enriched uranium typically requires more than military intervention; it calls for verified tracking of the material, sustained access to storage sites, and potentially downblending the uranium for civilian use. Davenport advocates for internationally monitored downblending as the safest alternative, underscoring that it’s technically simpler than extracting highly enriched material in a contested environment. However, both options depend entirely on favorable political conditions that are currently lacking.
As the administration works to dismantle Iran’s missile capabilities to weaken its nuclear breakout potential, these challenges remain distinct and complicated. The destruction of missile infrastructure can have immediate benefits, yet effectively securing enriched uranium involves a different set of requirements. Reliable intelligence and sustained access to storage sites are essential, but these aspects can only move forward in a political climate that supports such actions.
As of now, while the stance remains firm that Iran will not be permitted to develop a nuclear weapon, the question of how the enriched uranium will be secured lingers—without a tangible resolution in sight.
