ISLAMABAD — President Trump said he is willing to meet with senior Iranian leaders if a breakthrough is reached — as he brushed off the regime’s threats to boycott the latest round of peace talks.

“I have no problem meeting them,” Trump told The Post Monday. “If they want to meet, and we have some very capable people, but I have no problem meeting them.”

Trump’s willingness to meet with Tehran underscores the urgency surrounding the negotiations as the US-Iran cease-fire is set to expire Wednesday evening Washington time, per the president’s latest deadline.

Trump signaled that Iran must come to the table for serious discussion — just hours after Tehran claimed it would not be meeting the American delegation in Islamabad. 

“We’re supposed to have the talks,” Trump said in a brief interview, brushing aside doubts about whether negotiations would fall apart. “So I would assume at this point nobody’s playing games.”

The president confirmed that Vice President JD Vance, special envoy Steve Witkoff, and adviser Jared Kushner, his son-in-law, are set to head to Islamabad to prepare for the meetings.

“They’re heading over now,” Trump said.

The delegation is set to arrive Wednesday, sources told CNN, putting into question how the end of the cease-fire will play out up against the deadline.

Trump said it was “highly unlikely” for the cease-fire to be extended, noting that he expects the fighting to resume if no deal is made by then, Bloomberg reported. 

At the heart of the negotiations, Trump said, is one non-negotiable demand: Iran must abandon any pursuit of nuclear weapons.

“Get rid of their nuclear weapons. That’s all very simple,” he said. “There will be no nuclear weapon.”

He added that Iran has the potential to thrive if the nation’s leaders agree to end Iran’s nulear program once and for all.

“Otherwise, a wonderful country — it truly could be,” Trump said.

But the president declined to spell out what consequences Tehran could face if it refuses to comply or if talks collapse — particularly as the cease-fire deadline looms.

“Well, I don’t want to get into that with you,” he said when asked whether the US would escalate measures. “You can imagine. It wouldn’t be pretty.”

The president has previously threatened to destroy all Iranian bridges and power plants if the regime does not agree to a peace deal. 

Iran accused the Trump administration of making “excessive demands” and shifting positions during the negotiations, with Tehran claiming it would not join the peace talks this week. 

Iran’s position, however, could be all bluster in order for the Islamic regime to get the best deal possible, Pakistani sources told The Post. 

The current hard stance “is posturing to extract maximum advantage when [the] second round happens,” one source said, citing takeaways from discussions with the Iranian Foreign Ministry spokesman. 

The president appeared undaunted by Iran’s position, saying that he knows the best negotiation tactics and won’t be swayed by mounting criticism from Democrats in congress. 

“As a negotiator, and I am a great negotiator, how bad is it when you have people from your own country trying to reach a deal? They are helping the other side,” Trump vented. 

“The other side has nothing, they have no cards, but they are using this to delay. When Schumer was in, he was in Afghanistan for so long,” the president added. 

“I have only been in this for five weeks. I will not be rushed.” US negotiators, however, could be facing an uphill battle as the delegation from Iran’s Foreign Ministry appears to have been usurped by Tehran’s hardline Islamic Revolutionary Guard Corps (IRGC).

The IRGC has reportedly taken full control of Iran’s army and negotiating team, dictating a hard stance against the US and pushing out Iran’s moderates — who have been previously willing to make compromises, according to the Washington-based Institute for the Study of War think tank.
