Trump escalates papal feud, accuses Pope Leo of endangering Catholics over Iran

He's endangering a lot of Catholics and a lot of people
Trump's accusation against Pope Leo, mischaracterizing the pontiff's opposition to war as endorsement of Iranian nuclear weapons.

In the weeks following Pope Leo's public opposition to the U.S.-Israeli war on Iran, President Trump has escalated his characterization of the Chicago-born pontiff's peacemaking stance into something far more incendiary — accusing him of endorsing Iranian nuclear weapons, a claim without basis in anything Leo has said. Secretary of State Rubio is set to visit the Vatican on Thursday, carrying the language of dialogue and fraternity into a room that Trump's own words have made considerably harder to enter. It is an old tension in human affairs: the difficulty of reconciling the private work of diplomacy with the public theater of grievance.

  • Trump has accused Pope Leo of supporting Iran's right to nuclear weapons — a distortion of the pope's actual calls for ceasefire and diplomacy that inflames an already volatile dispute.
  • The attack lands just two days before Secretary of State Rubio is scheduled to meet Leo at the Vatican, turning what might have been a quiet repair mission into a high-stakes contradiction.
  • Ambassador Brian Burch insists no deep rift exists, framing the visit as 'authentic dialogue' — but the gap between that diplomatic language and Trump's public rhetoric is impossible to ignore.
  • Rubio's trip also includes meetings with Italian PM Meloni, whose own relationship with Trump has soured after she criticized his attacks on the pope and his strikes on Iran.
  • The visit falls on the first anniversary of Leo's papacy, and the unresolved question hanging over it is whether any conversation can close a gap that one party keeps publicly widening.

Donald Trump has sharpened his attacks on Pope Leo, claiming in a radio interview that the pontiff is willing to let Iran acquire nuclear weapons — a characterization that misrepresents Leo's actual position. The Chicago-born pope has never endorsed Iranian nuclear capability; he has consistently called for ceasefires and diplomatic solutions to the U.S.-Israeli war on Iran. Trump has reframed that peacemaking stance as something far more dangerous.

The accusation arrives two days before Secretary of State Marco Rubio is scheduled to meet Leo at the Vatican — a visit that appears designed, at least in part, to repair a relationship that has been fraying for weeks. U.S. Ambassador Brian Burch described the expected conversation as 'frank' but rooted in 'fraternity and authentic dialogue,' insisting the two institutions simply needed to better understand each other. The framing is careful and conciliatory.

The broader context complicates it. Trump had already called Leo weak in April and shared an AI-generated image depicting himself in a Christ-like pose. Rubio denied the Vatican trip was meant to 'smooth things over,' even as his presence there suggests otherwise. JD Vance, a Catholic convert, has meanwhile suggested the Vatican should stay in its lane on questions of war.

Rubio's mission extends to Italian PM Giorgia Meloni, once a close Trump ally, now estranged after she criticized Trump's attacks on the pope and his government's silence on the Iran strikes. Trump responded by threatening to pull U.S. troops from Italy. Rubio will meet Meloni and Foreign Minister Antonio Tajani on Friday.

The timing of the visit — coinciding with the first anniversary of Leo's papacy — adds a layer of symbolism to an already charged encounter. What remains unresolved is whether diplomatic conversation can do meaningful work when one side continues, publicly and loudly, to widen the very divide the other is trying to cross.

Donald Trump has turned up the volume on his quarrel with Pope Leo, claiming the pontiff is willing to let Iran develop nuclear weapons and, in doing so, is putting Catholics at risk. The accusation came during an interview with Hugh Hewitt, a conservative radio host, and lands just two days before Secretary of State Marco Rubio is scheduled to sit down with Leo at the Vatican—a meeting that appears designed, at least in part, to lower the temperature on a dispute that has been simmering for weeks.

The pope, who was born in Chicago and leads the Catholic Church from Rome, has never actually said Iran should possess nuclear weapons. What he has done, repeatedly and publicly, is oppose the war being waged against Iran by the United States and Israel, and he has called for ceasefires and diplomatic solutions as the conflict has spread into Lebanon and across the broader Middle East. Trump, however, has reframed this position as a kind of reckless endorsement of Iranian nuclear capability—a characterization that distorts the pontiff's actual stance.

Rubio, himself a Catholic, will arrive at the Apostolic Palace on Thursday morning. Brian Burch, the U.S. ambassador to the Holy See, told reporters on Tuesday that he expected the conversation to be "frank" but grounded in what he called "fraternity and authentic dialogue." Burch pushed back against the notion that a deep rift had opened between Washington and the Vatican, suggesting instead that both sides simply needed to understand each other better and work through their differences in conversation. The framing is diplomatic, almost gentle—the language of two institutions trying to find common ground.

But the context tells a different story. In April, Trump had already attacked Leo directly, calling him weak and suggesting he was failing in his role as pope. Trump also shared an artificially generated image showing himself as a Christ-like figure before deleting it and claiming it was meant to depict him as a doctor. These were not the gestures of a president interested in quiet negotiation. Rubio, when asked about the Vatican trip, denied it was meant to "smooth things over," though his presence there suggests otherwise. He acknowledged there was "a lot to talk about" with the Vatican but tried to minimize the significance of the disagreement.

Rubio's diplomatic mission extends beyond the Vatican. He will also meet with Italian Prime Minister Giorgia Meloni, who was once among Trump's closest European allies but has now found herself on the receiving end of his anger. She had criticized Trump's attacks on the pope and rebuked her own government for not opposing the strikes on Iran. Trump responded by threatening to withdraw U.S. troops from Italy—a threat that has left the relationship strained. Rubio will see both Meloni and Italy's foreign minister, Antonio Tajani, on Friday.

The vice president, JD Vance, has added his own voice to the criticism. Vance, a Catholic convert, has suggested the Vatican should confine itself to matters of morality and be cautious about weighing in on theology and questions of war. Both Vance and Rubio attended Leo's installation as pope last May and had a private audience with him the following day, at which point they delivered an invitation from Trump to visit the White House—an invitation the pope has not yet accepted.

The timing of Rubio's visit coincides with the first anniversary of Leo's papacy, a detail that may or may not be coincidental. What is clear is that Trump's public attacks are making the work of diplomatic repair considerably harder. The president continues to mischaracterize the pope's position on Iran while simultaneously sending his secretary of state to the Vatican to talk things through. It is a contradiction that will hang over Thursday's meeting, and it raises a question about whether any conversation, however frank or fraternal, can bridge a gap when one side is still actively widening it from the other.

Nations have disagreements, and I think one of the ways that you work through those is through fraternity and authentic dialogue.
— Brian Burch, U.S. Ambassador to the Holy See
I think he's endangering a lot of Catholics and a lot of people. But I guess if it's up to the pope, he thinks it's just fine for Iran to have a nuclear weapon.
— Donald Trump, in interview with Hugh Hewitt

Why does Trump keep saying the Pope supports Iran having nuclear weapons when that's not what the Pope actually said?

Model

Because it's a more powerful accusation than the truth. The Pope opposes the war itself—that's a harder target to attack directly without looking like he's the warmonger. So Trump inverts it: he makes the Pope's peace position sound like nuclear appeasement.

Inventor

But Rubio is going to the Vatican to smooth things over. Doesn't that undercut Trump's position?

Model

On the surface, yes. But Rubio's trip also gives Trump cover. He can keep attacking while his secretary of state does the diplomatic work. If it works, Trump takes credit. If it fails, he can say the Pope was unreasonable.

Inventor

What about Meloni? She was supposed to be Trump's ally in Europe.

Model

She was, until she defended the Pope. That's the real story—Trump is punishing people who don't fall in line with his framing, even longtime allies. Meloni criticized his attacks on Leo, and now she's getting threatened with troop withdrawals.

Inventor

Is there any chance this actually gets resolved?

Model

Not while Trump keeps making false claims in public. Rubio can talk dialogue all he wants, but every time Trump goes on the radio and misrepresents what the Pope said, he's poisoning the well. The Vatican knows what Leo actually believes. They're not going to pretend otherwise.

Inventor

What does the Pope want from all this?

Model

Probably just to be left alone to do his job. He's called for peace in the Middle East. Trump has made that a personal attack on himself. Leo didn't ask for this fight.
