The Iranian authorities must make the right decision and abandon the possibility of acquiring nuclear weapons. Otherwise, they will leave the United States with no alternative, US President Donald Trump told reporters at the White House.

"This is really crunch time. I would tell you for Iran and, for their country, this is a very important time for Iran. This is the most important time in the history of Iran for Iran, and I hope they do what's right. I'd love to see a peace deal, a strong peace, so they cannot have a nuclear weapon," Trump said.

"They [i.e. Iran] have everything you need. The people are incredible. They have vast amounts of oil and assets. We want it to be a successful country," he added.

"We don't wanna do anything that's gonna get in the way of that, but they can't have a nuclear weapon. And if they choose to go a different route, it's gonna be a very sad thing. And and it's something we don't wanna have to do, but we have no choice. They're not gonna have a nuclear weapon," the US president concluded.
