Donald Trump has said he is ready to renew attacks against Iran if progress is not made at eleventh-hour talks in Pakistan, with the US military “raring to go”.
The American president also told CNBC he did not want to extend a ceasefire with Tehran as the deadline on the two-week truce looms.
He insisted the US was in a strong position and was “going to end up with a great deal”.
Uncertainty has hung over fresh negotiations between the two sides in Islamabad, amid the ongoing tense stand-off in the Strait of Hormuz, which continues to disrupt international shipping.
The effective closure of the critical supply route during the conflict has inflicted a global economic shock and sent energy prices soaring.
UK Foreign Secretary Yvette Cooper, who has been holding discussions with counterparts aimed at safeguarding the strategic waterway, has described it as “a critical diplomatic moment” in the crisis.
US vice president JD Vance will again lead the American delegation while Iran’s parliament speaker Mohammad Bagher Qalibaf has been tipped as Tehran’s chief negotiator.
The timing of the talks has not been confirmed.
Threatening to resume strikes if a deal is not struck with Iran soon, Mr Trump said: “Well, I expect to be bombing because I think that’s a better attitude to go in with.
“But, you know, we’re ready to go. I mean, the military is raring to go.”
Mr Trump also said he did not want to extend the current ceasefire, which he said runs out on Wednesday.
He told CNBC: “I don’t want to do that. We don’t have that much time.”
The president said: “What I think is that we’re going to end up with a great deal.”
He added: “I think they (Iran) have no choice.
“We’ve taken out their navy, we’ve taken out their air force, we’ve taken out their leaders.”
He again claimed “regime change” and said those now in charge were “much more rational”.
Mr Trump said: “I think we’re in a very strong negotiating position to do what other presidents should have done during a 47-year period.”
Meanwhile, Mr Qalibaf has accused the US president of seeking to turn the negotiating table into a “table of surrender”.
“We do not accept negotiations under the shadow of threats,” he wrote in an X post and said Iran was preparing “to reveal new cards on the battlefield”.
