US President Donald Trump said that Washington remains open to a diplomatic breakthrough with Iran but warned that American military operations would resume if negotiations fail, signalling that the recent pause in fighting may only be temporary.

Speaking to reporters aboard Air Force One, Trump said he believed there was "a good chance" diplomacy could produce results, while making it clear that the United States was prepared to return to military action if talks do not progress.

"I have a lot of patience... We'll see what happens. I think there is a good chance that something could happen," Trump said. "If it doesn't, we go back to doing what we were doing two days ago."

Trump's remarks come after three consecutive days without direct exchanges of fire between the United States and Iran following nearly two weeks of renewed US strikes. The pause has fueled hopes that diplomacy could prevent another escalation after earlier efforts to stabilise the situation failed.

The US President claimed Iranian officials had sought a meeting following recent military operations.

"The only reason they want to meet is because we've been hitting them very hard," Trump said.

Iran, however, has rejected suggestions that direct negotiations are underway. Officials in Tehran said there have been no face-to-face talks with Washington and maintained that any communication has been conducted through intermediaries.

Trump also rejected suggestions that months of military operations had significantly reduced US weapons stockpiles.

"We have a lot of ammunition," he said, adding that the United States possessed more military supplies than it would likely need.

At the same time, Trump argued that US inventories would have been even larger had substantial military assistance not been provided to Ukraine during its war with Russia.

Regional tensions remain high

Although the temporary halt in direct hostilities has eased immediate concerns over a broader regional conflict, security threats continue across the Middle East.

Saudi Arabia said it intercepted drones launched by Iran-linked groups operating from Iraq, while Yemen's Iran-backed Houthi rebels claimed attacks targeting Saudi oil infrastructure.

Abraham Accords and other foreign policy remarks

Asked whether Saudi Arabia could join the Abraham Accords, the US-backed agreements aimed at normalising relations between Israel and Arab nations, Trump said no discussions had taken place on the issue.

"We haven't talked, no," he said.

Trump also suggested that money seized from Venezuela could be directed toward the US military and claimed similar financial gains could eventually come from Iran.

"We are taking in a lot of money. Billions and billions of dollars," Trump said. "That will happen with Iran too."
