US Vice President JD Vance, echoing President Donald Trump, says it is important to prevent Iran from having a nuclear weapon to prevent other countries from pursuing them.

“I think it’s important for the American people and all of you to appreciate that when we say that it’s not just that Iran cannot have a nuclear weapon, it’s what would happen if the Iranians did get a nuclear weapon,” he tells reporters during a press briefing.

“We know that a lot of nations all across the Gulf would then want their own nuclear weapon, and then a lot of nations all across the world, and what has been a very effective bright spot of American foreign policy, really for the last 20 or so years, would disappear overnight.”

He adds, “If you have every country in the world scrambling to try and get a nuclear weapon, it would make us all much less safe, and Iran would really be the first domino in what would set off a nuclear arms race all around the world.”
