U.S. Intelligence: Military Operations Haven't Degraded Iran's Nuclear Capabilities

The bombing campaign that began in late February has not slowed Iran's march toward a nuclear weapon, according to assessments now circulating through U.S. intelligence agencies. Operation Epic Fury, as it has been named, has targeted Iranian military infrastructure across the country—but the nuclear program itself has continued on largely uninterrupted.

This represents a sharp reversal from what happened last June. Then, in an operation called Midnight Hammer, American and Israeli forces struck three of Iran's most critical nuclear sites: Natanz, Fordow, and Isfahan. Those attacks caused significant damage and, by intelligence estimates, pushed back Iran's timeline to weaponization by several months—from nine months to roughly a year. It was a surgical blow, precisely aimed at the infrastructure that mattered most.

But the intervening months have changed the calculus. The ongoing military campaign has been broader and less focused. The U.S. has concentrated its strikes on Iran's conventional military forces and the industrial base that supports them—the armor, the air defenses, the supply chains. Israel has hit some nuclear targets, but not with the intensity or coordination of last year's operation. The result, according to intelligence officials, is that Iran's nuclear program has recovered much of the ground it lost. The delay that Midnight Hammer achieved appears to be eroding.

The fundamental problem is one of knowledge and access. To truly cripple Iran's nuclear ambitions would require destroying or removing its stockpile of highly enriched uranium—the material that can be weaponized. But nobody outside Iran's government knows exactly where that stockpile is kept. The UN's nuclear watchdog agency believes it is stored in an underground complex somewhere near Isfahan, but belief is not certainty, and underground facilities are notoriously difficult to target with precision.

The White House has pushed back against the intelligence assessment. Spokeswoman Olivia Wales argued that Operation Epic Fury succeeded in a different way—by dismantling the conventional military apparatus that Iran had built as a shield around its nuclear program. She invoked President Trump's long-standing position that Iran will never be permitted to develop a nuclear weapon. "He does not bluff," she said.

Yet the diplomatic track has stalled. Negotiations between Washington and Tehran have made no meaningful progress, with the nuclear question remaining the central obstacle neither side can move past. And in the absence of diplomacy, the military situation has grown more volatile. On Monday, tensions spiked again over the Strait of Hormuz, the narrow waterway through which roughly a third of the world's seaborne oil passes. Trump told Fox News that if Iranian forces attempt to block that passage, Iran will be "blown off the face of the Earth." He emphasized that American military strength in the region continues to grow—more weapons, more ammunition, more bases stocked with equipment ready for deployment.

Central Command reported that its forces had already sunk six Iranian small boats that were moving toward civilian vessels in the strait. The message was clear: the U.S. military is prepared to enforce freedom of navigation by force if necessary. What remains unclear is whether that military readiness can accomplish what the bombing campaign has not—whether it can actually stop Iran's nuclear program, or whether it will simply manage the confrontation indefinitely.
