Talks between Iran and the U.S. wrapped up in Geneva Thursday as officials cited "significant progress" and announced a next meeting set for Vienna within days.
Yet despite senior U.S. officials describing the third round as "positive," per State of the Union address Feb. 24, the president said he prefers a diplomatic solution.
"My preference is to solve this problem through diplomacy, but one thing is certain: I will never allow the world's number one sponsor of terror, which they are by far, to have a nuclear weapon," the president said. "Can't let that happen."
As the Geneva talks unfolded Thursday, Ali Shamkhani, a senior adviser to Iran’s Supreme Leader, Ayatollah Ali Khamenei, also wrote on X that if the main U.S. concern is preventing a nuclear weapon, that stance "aligns" with Khamenei’s fatwa and Iran’s defensive doctrine.
He added that Iranian Foreign Minister Abbas Araghchi has "sufficient support and authority" to come to a final agreement in the talks.
The development came as the U.S. continues assembling military assets, including a fleet of aircraft and warships in the Middle East.
