Secretary of defence Pete Hegseth opens the news briefing by saying US forces "conducted a precision strike in the middle of the night against three nuclear facilities in Iran".
The aim was "to destroy or severely degrade Iran's nuclear programme".
"It was an incredible and overwhelming success," he declares. "We devastated the Iranian nuclear programme."
Hegseth goes on to say that President Trump has stated for over a decade that "Iran must not get a nuclear weapon", and thanks to last night's decision, "Iran's nuclear ambitions have been obliterated".
This operation was the "final blow" to Tehran's nuclear programme, Hegseth claims, and describes President Trump's plan as "bold" and "brilliant".
"When this president speaks, the world should listen. And the US military - we can back it up. The most powerful military the world has ever known - no other country on planet Earth could have conducted the operation that the chairman is going to outline this morning."
Nonetheless, President Trump "seeks peace", Hegseth continues, adding that Iran "should choose that path".
The defence secretary also reiterated that Iran should not retaliate, as the president emphasised last night.
"Every American involved in this operation performed flawlessly, and I want to give recognition to our allies in Israel as well," he adds.
"The United States does not seek war, but let me be clear - we will act swiftly and decisively when our people, our partners, or our interests are threatened."
