President Donald Trump has consistently stated for 14 years that Iran must not obtain a nuclear weapon, according to the White House.
“President Donald J. Trump has never wavered in his stance that Iran cannot be allowed to have a nuclear weapon — a pledge he has made repeatedly, both in office and on the campaign trail,” the White House said in a statement.

The White House listed 15 times Trump said Iran cannot be allowed to have a nuclear weapon since he began his second term in January 2025, and over 40 times while on the campaign trail or during his first term.
The earliest example listed is from a 2011 tweet, where Trump described Iran’s “quest for nuclear weapons” as “a major threat to our nation’s national security interests.”
Iran’s quest for nuclear weapons is a major threat to our nation’s national security interests. We can’t allow Iran to go nuclear.

In a more fleshed-out explanation of his belief during a 2015 campaign speech in Des Moines, Iowa, Trump said nuclear weapons in the hands of rogue actors pose a grave risk to the United States.
“We have a game changer now, and the game changer is nuclear weapons. We really do have to get strong, and we have to get strong fast. We can’t let Iran get a nuclear weapon. We can’t do it. Can’t do it. We cannot let that happen.”
Trump added that nuclear weapons are not “like soldiers in uniform shooting rifles.”

“You can take out the east coast of this country,” he said. “You can take out large sections of the Midwest. You can take out things that were unthinkable, the power. And we have to be in a position where that never, ever, ever happens.”
President Trump has been consistent on Iran.
