Speaking in an interview with CNBC, Trump said his administration remained focused on preventing Iran from acquiring nuclear weapons and expressed confidence that ongoing negotiations were moving in Washington's favour.

"We're negotiating, and we'll see whether or not. I think they've agreed to just about everything we need," Trump said.

He described the US objective as "the denuking of Iran" rather than a conventional military campaign.

"This is the denuking of Iran. You can't let them have a nuclear weapon," Trump said.

Asked whether he was seeking regime change in Tehran, Trump said that was not his goal.

"I'm not looking for regime change. I'm looking for something very simple. They cannot have a nuclear weapon."

Trump said US military operations had significantly weakened Iran's military capabilities since he returned to office.

"I've defeated them militarily. They're totally defeated militarily. They have some missiles left, we could wipe them out too."

He argued that the campaign had sharply reduced Iran's economic strength.

"They have 300 per cent inflation, they're making no money."

Trump said Washington could eventually become a supplier of agricultural products to Iran if negotiations produced an agreement.
