The “bunker busting” bombs dropped on Iranian nuclear sites last month by U.S. forces have degraded Tehran’s atomic program by up to two years, the Pentagon confirmed Wednesday.

“We have degraded their program by one to two years, at least intel assessments inside the Department [of Defense] assess that,” Defense Department spokesman Sean Parnell told reporters. 

“We believe that Iran’s nuclear capability has been severely degraded, perhaps even their ambition to build a bomb,” he added, though security experts have told Fox News Digital that Tehran is unlikely to be deterred in its ambition to build a nuclear weapon.

The U.S. has fervently denied that any intelligence suggests Iran was successful in moving its nuclear capabilities off site. Secretary of Defense Pete Hegseth became angry when asked about the possibility by reporters.

Fox News Digital has confirmed that Israel is continuing to monitor the security situation. 

Iranian Foreign Minister Abbas Aragchi this week acknowledged that there was severe damage to the Fordow facility, though he also insisted that “the technology and knowhow is still there.”

“No one exactly knows what has transpired in Fordow. That being said, what we know so far is that the facilities have been seriously and heavily damaged,” Aragchi said during a CBS interview this week.

Though according to Parnell on Wednesday, “All of the intelligence that we’ve seen (has) led us to believe that Iran’s – those facilities especially, have been completely obliterated.”
