An initial classified US assessment of Donald Trump’s strikes on Iran’s nuclear facilities over the weekend says they did not destroy two of the sites and likely only set back the nuclear program by a few months, according to two people familiar with the report.
The report produced by the Defense Intelligence Agency – the intelligence arm of the Pentagon – concluded key components of the nuclear program, including centrifuges, were capable of being restarted within months.
The report also found that much of Iran’s stockpile of highly enriched uranium that could be put to use for a possible nuclear weapon was moved before the strikes and may have been moved to other secret nuclear sites maintained by Iran.
The findings by the DIA, which were based on a preliminary battle damage assessment conducted by US Central Command, which oversees US military operations in the Middle East, suggests Trump’s declaration about the sites being “obliterated” may have been overstated.
Trump said in his televised address on Saturday night immediately after the operation that the US had completely destroyed Iran’s enrichment sites at Natanz and Fordow, the facility buried deep underground, and at Isfahan, where enrichment was being stored.
“The strikes were a spectacular military success. Iran’s key nuclear enrichment facilities have been completely and totally obliterated. Iran, the bully of the Middle East, must now make peace,” Trump said in his address from the White House.
While the DIA report was only an initial assessment, one of the people said if the intelligence on the ground was already finding within days that Fordow in particular was not destroyed, later assessments could suggest even less damage might have been inflicted.
Long regarded as the most well-protected of Iran’s nuclear sites, the uranium-enrichment facilities at Fordow are buried beneath the Zagros mountains. Reports have suggested that the site was constructed beneath 45-90 metres (145-300ft) of bedrock, largely limestone and dolomite.
The White House disputed the intelligence assessment, which was first reported by CNN. “The leaking of this alleged assessment is a clear attempt to demean President Trump, and discredit the brave fighter pilots who conducted a perfectly executed mission to obliterate Iran’s nuclear program,” White House press secretary Karoline Leavitt said in a statement.
The Guardian revealed last Wednesday that top political appointees at the Pentagon had been briefed at the start of Trump’s second term that the 30,000lb “bunker buster” GBU-57 bombs meant to be used on Fordow would not completely destroy the facility.
In that briefing, in January, officials were told by the Defense Threat Reduction Agency at the Pentagon that developed the GBU-57 that the bombs would not penetrate deep enough underground and only a tactical nuclear weapon would wipe out Fordow.
The US strikes against Iran’s nuclear facilities involved B2 bombers dropping 12 GBU-57s on Fordow and two GBU-57s on Natanz. A US navy submarine then launched roughly 30 Tomahawk missiles on Isfahan, US defense officials said at a news conference Sunday.
Defense secretary Pete Hegseth repeated Trump’s claim at the news conference that the sites had been “obliterated”, but the chair of the joint chiefs of staff, Gen Dan Caine, who helped oversee the operation, was more measured in his remarks.
Caine said that all three of the nuclear sites had “sustained severe damage and destruction” but cautioned that the final battle-damage assessment for the military operation was still to come.
