The Iran Nuke Danger – is it growing instead of decreasing? As the conflict between the U.S. and Iran enters its fourth week, the focus of the international community has shifted from naval blockades to a far more existential threat. Ian Stewart, a preeminent nuclear security analyst and director at the Washingtoner Bureau of the James Martin Center for Nonproliferation Studies (CNS), has issued a detailed assessment of the Iran nuke danger, warning that the path to a peaceful resolution is currently blocked by a stockpile of 440kg of Highly Enriched Uranium (HEU).
Despite the massive bombardment of Iranian military assets during Operation Epic Fury, Stewart points out that the core of the Iran nuke danger remains intact. This material, enriched to 60% purity, is only a “short technical step” away from weapons-grade level. Stewart argues that the U.S. cannot simply declare victory and withdraw while this stockpile exists, as it provides Tehran with a rapid “breakout” capability that could lead to a functional nuclear weapon in a matter of weeks.
The Highly Enriched Uranium (HEU) Crisis
The Iran nuke danger identified by Stewart centers on the persistence of nuclear materials despite the destruction of known enrichment facilities.
-
Strategic Stalemate: Stewart believes the U.S. has no clear path to end the war without addressing the 440kg of 60%-enriched uranium.
-
The “Hiding” Risk: There is a substantial risk that Iran could use the chaos of the war to hide its HEU in secret, hardened locations, pursuing a bomb with even greater motivation following U.S. airstrikes.
-
The Ground Force Dilemma: In the absence of a mediated deal, Stewart suggests the only alternative to neutralize the Iran nuke danger would be a high-risk deployment of U.S. ground forces to secure the material.
Why Air Superiority Isn’t Enough
While President Trump has threatened to continue bombing Iran power plants, Stewart’s analysis suggests that conventional strikes do not solve the underlying Iran nuke danger. In fact, military action may have inadvertently increased the threat by driving the Iranian program further underground. Without a “mediated deal” to eliminate the HEU—which Stewart currently sees no signs of—the conflict risks becoming an endless cycle of escalation with no verifiable way to ensure Iran remains non-nuclear.
The Iran nuke danger is compounded by the fact that the International Atomic Energy Agency (IAEA) has lost critical monitoring access since the onset of the 2026 hostilities. Stewart warns that “walking away” now would leave a radicalized Iranian leadership with the components for a nuclear deterrent and the ultimate motive to use them as a shield against future Western intervention.
A Conflict with No Clear Exit
Ultimately, the Iran nuke danger serves as the ultimate “poison pill” for any peace negotiations. Stewart’s assessment at RUSI highlights a grim reality: as long as the HEU exists, the U.S. victory remains hollow. The alternative—a full-scale ground invasion to seize the material—would fulfill the most dire predictions of a “long, painful war.”
As the 48-hour ultimatum on Iran’s energy grid looms, the world is realizing that the lights going out in Tehran is only half the story. The real Iran nuke danger is what happens in the dark.
