US President Donald Trump’s strikes on Iran’s nuclear facilities over the weekend may not have had the desired effect, according to a classified US assessment. The report, produced by the Defense Intelligence Agency, suggests that two of the sites were not destroyed and that the nuclear program may only be set back by a few months.
The assessment found that key components of the nuclear program, including centrifuges, can be restarted within months. Additionally, much of Iran’s stockpile of highly enriched uranium, which could be used for a possible nuclear weapon, was moved before the strikes and may have been moved to other secret nuclear sites maintained by Iran.
Trump had claimed that the US had completely destroyed Iran’s enrichment sites at Natanz and Fordow, as well as the facility buried deep underground in Isfahan. However, the DIA report contradicts this claim, with one source stating that Fordow was not destroyed and later assessments could suggest even less damage might have been inflicted.
The White House disputed the intelligence assessment, calling it a “clear attempt to demean President Trump” and discredit the military operation. The US vice-president admitted that Washington did not know where Iran’s stockpile of highly enriched uranium was, saying “we are going to work in the coming weeks to ensure that we do something with that fuel”.
The International Atomic Energy Agency (IAEA) has also reported that it can no longer account for Iran’s stockpile of 400kg of uranium enriched to 60% purity. The US strikes involved B2 bombers dropping bombs on Fordow and Natanz, as well as a navy submarine launching Tomahawk missiles on Isfahan.
