“No, I wouldn’t use it,” Trump told reporters at the White House, referring to nuclear weapons. “Why would I use a nuclear weapon when we’ve, in a very conventional way, decimated them without it?” he added, while also stating that such weapons “should never be allowed to be used by anybody.”

The remarks come after Trump earlier this month warned that Iran faced destruction, comments that drew scrutiny before a ceasefire was agreed and subsequently extended.

During the conflict, Vice President JD Vance said Washington was prepared to intensify its military response using capabilities not previously deployed, though the White House denied that nuclear weapons were under consideration.

Trump reiterated that his objective was to prevent Iran from acquiring nuclear weapons, saying he sought an Iran “without a nuclear weapon” that could threaten U.S. cities or regional stability. Tehran has consistently denied pursuing nuclear arms, and the International Atomic Energy Agency has said an atomic weapon was not imminent prior to the outbreak of hostilities.

The United States remains the only country to have used nuclear weapons in combat, during the final stages of World War II, when atomic bombs were dropped on Hiroshima and Nagasaki. Israel is widely believed to possess nuclear weapons but has not publicly confirmed their existence.

Trump’s statement appears to contrast with longstanding U.S. nuclear doctrine, which has not ruled out the potential use of nuclear weapons under certain conditions.

Previous administrations, including that of Barack Obama, have advocated for reducing nuclear risks while maintaining deterrence capabilities.
