Deep Look
CIA Chief Tells Lawmakers Iran Nuclear Program Delayed Years By Devastating Strikes On Metal Conversion Facility
WASHINGTON — CIA Director John Ratcliffe told skeptical U.S. lawmakers last week that recent American military strikes have severely crippled Iran’s nuclear ambitions, setting the country’s program back by years, according to a U.S. official familiar with the classified briefing.
The official, who spoke anonymously due to the sensitivity of intelligence details, said Ratcliffe highlighted the destruction of Iran’s lone metal conversion facility as a decisive blow that significantly reduces Tehran’s immediate ability to produce a nuclear weapon.
Metal Conversion Facility Obliterated
The strikes, ordered by President Donald Trump, targeted three major Iranian nuclear sites — Fordo, Natanz, and Isfahan. But Ratcliffe underscored that the most consequential hit was on the metal conversion facility located at Isfahan. This facility played a critical role in transforming enriched uranium gas into dense metal—a crucial step in producing a bomb’s explosive core.
“It was obliterating like nobody’s ever seen before,” Trump said Sunday on Fox News Channel’s “Sunday Morning Futures,” claiming the strikes ended Iran’s nuclear ambitions “at least for a period of time.”
Ratcliffe informed lawmakers that while some enriched uranium remains buried under rubble at Fordo and Natanz, Iran’s lack of a functional metal conversion facility effectively prevents it from moving closer to weaponization, the U.S. official said.
Mixed Intelligence Assessments
Despite Trump’s triumphal declarations, intelligence assessments have varied in tone. A preliminary report from the U.S. Defense Intelligence Agency concluded that the strikes caused significant damage to the facilities but did not completely destroy them.
Rafael Grossi, head of the International Atomic Energy Agency (IAEA), said on CBS’ “Face the Nation” that Iran’s nuclear sites were “destroyed to an important degree,” yet cautioned, “some is still standing.” Grossi stressed that Iran retains the expertise to rebuild if it chooses, warning, “Frankly speaking, one cannot claim that everything has disappeared, and there is nothing there.”
Iran’s Knowledge Cannot Be Erased
A lingering concern for both American and international officials is that while infrastructure can be bombed, technical know-how cannot be eradicated.
“You cannot undo the knowledge that you have or the capacities that you have,” Grossi said, emphasizing the need for diplomacy to ensure Iran does not simply rebuild its nuclear program once tensions subside.
This sentiment is echoed by Democratic lawmakers pressing for clarity on how lasting the damage truly is. Some remain unconvinced that physical destruction alone guarantees a permanent halt to Iran’s ambitions.
Trump, U.S. Officials Tout Success
President Trump and top U.S. officials remain adamant that Iran’s nuclear aspirations have been dealt a crippling blow.
Defense Secretary Pete Hegseth described the targeted sites as “destroyed.” Secretary of State Marco Rubio, speaking last week at a NATO summit, reinforced the administration’s position, declaring, “You can’t do a nuclear weapon without a conversion facility. We can’t even find where it is, where it used to be on the map. The whole thing is just blackened out. It’s gone. It’s wiped out.”
Rubio’s comments underscore the Pentagon’s confidence that the metal conversion facility’s destruction has denied Iran a crucial capability.
Iran’s Air Defenses Severely Damaged
Ratcliffe also disclosed to lawmakers that Iran’s air defense network was significantly damaged during the 12-day U.S.-Israeli assault. This leaves Iran’s nuclear infrastructure more vulnerable to future Israeli strikes, should Iran attempt to rebuild quickly.
Israeli intelligence assessments reportedly align with U.S. conclusions. A senior Israeli military official, speaking anonymously, confirmed that Iran’s capacity to enrich uranium to weapons-grade levels has been neutralized “for a prolonged period.”
In addition to physical damage to nuclear sites, Israeli officials believe key Iranian scientists have been killed, and Iran’s missile production industry and air defenses have suffered substantial setbacks.
Debate Over Long-Term Impact Continues
Despite the apparent success of the strikes, officials and experts warn that Iran’s nuclear ambitions are far from eliminated. While critical facilities may lie in ruins, Iran’s technical expertise and determination remain intact.
Grossi and other international officials caution that only diplomacy and rigorous inspections can ensure Iran’s nuclear program remains constrained in the long term. Without a negotiated agreement, some fear Iran could eventually rebuild what was lost, albeit more slowly and at great cost.
For now, the strikes have delivered a dramatic blow. But the question of whether they permanently cripple Iran’s nuclear ambitions—or merely delayed them—continues to divide policymakers and intelligence analysts alike.
