Trump says damage from Iran strikes severe despite ‘inconclusive’ intelligence

US President Donald Trump said on Wednesday that the damage to Iranian nuclear sites from American missile strikes over the weekend was severe, even as he acknowledged that the available intelligence on the matter was inconclusive.

His comments followed reports by Reuters and other media outlets on Tuesday revealing that the US Defence Intelligence Agency had assessed that the strikes had set back Iran's nuclear program by just a few months, despite administration officials saying the program had been obliterated.

"The intelligence was ... very inconclusive," Trump told reporters while meeting NATO Secretary General Mark Rutte ahead of a summit in The Hague.

"The intelligence says, 'We don't know, it could have been very severe.' That's what the intelligence says. So I guess that's correct, but I think we can take the 'we don't know'. It was very severe. It was obliteration," Trump added.

Later, during the same round of comments, Trump argued that Iran's nuclear deal had been set back "basically decades, because I don't think they'll ever do it again".

Trump, who arrived in the Netherlands late on Tuesday for NATO's annual leaders' summit, was sitting beside Secretary of State Marco Rubio and Secretary of Defence Pete Hegseth, who both also cast doubt on the reliability of the DIA assessment.

Rubio said the US was opening an investigation into the leak of the DIA report. He also suggested the report's contents had been misrepresented in the media.

At the summit, NATO member states are set to announce their joint intention to raise defence spending to 5% of gross domestic product.

While some countries have suggested they may not in fact reach that threshold, the Trump administration has pointed to the expected commitment as a significant foreign policy victory.
