“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.

Speaking at a Turning Point USA event, Vance said distrust between Washington and Tehran remains a fundamental obstacle to any durable agreement. “There is a lot of, of course, mistrust between Iran and the United States of America.

You are not going to solve that problem overnight,” he said, while adding that Iranian negotiators appeared willing to reach a deal.Vance, who participated in recent negotiations held in Pakistan, said he was cautiously optimistic about the trajectory of talks.

“I feel very good about where we are,” he said, signaling confidence in ongoing diplomatic efforts despite recent setbacks.Donald Trump said on Tuesday that discussions aimed at ending the Iran war could resume in Pakistan within days, following the collapse of negotiations over the weekend.

The breakdown prompted Washington to impose a blockade on Iranian ports, escalating economic and military pressure on Tehran.A two-week ceasefire between US and Iranian forces remains in effect, with one week remaining, offering a limited window for diplomatic engagement.

The pause in hostilities follows weeks of intensified conflict that began on February 28, when US and Israeli forces launched strikes on Iran.Tehran retaliated with attacks targeting Israel and Gulf states hosting US military bases, expanding the geographic scope of the conflict.

Subsequent US-Israeli operations inside Iran, along with Israeli strikes in Lebanon, have resulted in significant casualties and widespread displacement, according to official accounts.

The evolving situation underscores the complexity of negotiations, with diplomatic momentum constrained by entrenched mistrust and ongoing military developments.
