Public tensions have surged unusually between U.S. President Donald Trump and Pope Leo XIV concerning the war in Iran.
Appointed in May 2025, the American-born Pope—formerly Cardinal Robert Prevost—initially adopted a quieter tone compared to his predecessor, Pope Francis, who was known as a fierce critic of the Trump administration.
Tensions between the Vatican and the White House had been rising for months. However, the dispute escalated sharply when the Pope directly named Trump.
Foreign Policy

On Sunday, Trump posted a lengthy message on social media platform Truth Social accusing the Pope of being “weak on crime control and a failure in foreign policy.”
“I cannot accept the Pope’s view that Iran having nuclear weapons is okay,” Trump wrote.
“Nor can I accept the Pope’s criticism of the U.S. for attacking Venezuela, a country that sends massive amounts of drugs to America and empties its jails by releasing murderers and drug traffickers into our nation.”
Trump later posted an image believed to be AI-generated depicting himself as Jesus Christ healing a sick man. This post sparked strong criticism from religious leaders and commentators, and was eventually removed.
Trump’s post was a response to the Pope’s rejection of his threat to “destroy Iranian civilization” over Tehran’s refusal to comply with demands regarding its nuclear program and the Hormuz Strait.
The Pope called the threat “completely unacceptable” and urged Catholics to pressure political leaders to work for peace.
He had previously mentioned Trump by name. On March 31, the Pope told journalists, “I have heard that President Trump recently wants to end the war. I hope he is seeking options to stop it.”
On Sunday, the 70-year-old Pope renewed his call for leaders to end the ongoing bloodshed.
Since taking office last year, Pope Leo emphasized the need for an immediate ceasefire in Gaza, the release of hostages, and guaranteed humanitarian access.
In August 2025, Pope Leo condemned the “collective punishment” and forced displacement faced by Palestinians, describing the situation in Gaza as unacceptable.
Addressing 140 million Catholics worldwide in his Christmas speech, he highlighted the dire conditions in Gaza.
While there has been no public dispute over Gaza, the Pope has privately challenged American and Israeli military operations.
In January this year, the Pope expressed concern regarding the U.S. military’s detention of Venezuelan President Nicolas Maduro.
He called for support of Venezuela’s sovereignty, adherence to constitutional rule of law, and respect for human rights.
Immigration

Immigration has also emerged as a major point of contention.
Pope Leo has continuously criticized Trump’s tough immigration stance, framing it as a moral responsibility grounded in the Gospel’s compassion and respect for human dignity.
In November 2025, the Pope stated that foreigners in America were facing “harsh and humiliating treatment.” American Catholic bishops also issued a statement expressing concerns over the fear and anxiety created by deportations and immigration enforcement.
The Pope emphasized, “We need to find humane ways to treat people.” However, he also added, “Every country has the right to determine who may enter, how many, and when at its borders.”
In October, during an address at St. Peter’s Square, the Pope urged Catholics to avoid indifference or discrimination against migrants. He also raised questions about whether Trump’s policies aligned with the Church’s ‘pro-life’ values, a critique that sparked debate among traditionalist Catholic circles.
Religion and Political Authority
On Sunday, Trump accused the Pope on social media of stepping outside his legitimate domain, stating, “I do not want a Pope who criticizes the President of the United States. I was elected by a large majority, and I am doing the job accordingly.”
Trump hinted that Leo was appointed Pope mainly because he is American: “If I were not in the White House, Leo wouldn’t be the Pope of the Vatican.”
Heading on an 11-day African tour on Monday, the Pope refused to engage in a personal debate with Trump during the flight.
“I am not a politician and do not wish to debate with Trump,” the Pope said.
“I will continue to speak out against war, and emphasize peace, dialogue, and multilateralism.”
The Trump administration maintains that “the Pope is not afraid of the Trump administration,” noting that he continues to speak in defense of the Gospel.
In the 2024 U.S. election, 55% of Catholic voters supported Republicans. Catholics make up 20% of the American population, and Vice President JD Vance is also Catholic.
The Trump administration has maintained close ties with conservative Evangelical Protestant leaders, portraying the Iran war in religious terms.
Expert Opinions

Experts say the Pope intends to pose a moral challenge to Trump and his foreign policy objectives on the global stage through his recent remarks.
“He speaks cautiously to avoid accusations that the Vatican is lenient on Trump because he is American,” said Italian Vatican affairs expert Massimo Fagioli.
“Leo is a thoughtful speaker. I don’t believe these comments were made casually.”
Chicago Cardinal Blaise Cupich, close to the Pope, noted that like previous popes, the current pontiff sends messages to world leaders to distance themselves from war.
“The difference now is that the messenger speaks in a way that resonates with the American and English-speaking world,” he added.
Marie Dennis, former staff member of the international Catholic peace movement Pax Christi, described the Pope’s recent comments and direct appeal to Trump as “a reflection of the hearts of people weary of ongoing violence.”
“It is an effort to bring together all those tired of relentless violence who expect courageous leadership,” Dennis stated.
