US President Donald Trump has intensified his criticism of Pope Leo XIV, accusing the pontiff of undermining global security with remarks on war, immigration and diplomacy, in a dispute that risks straining relations between Washington and the Vatican.
In an interview with conservative commentator Hugh Hewitt, Trump claimed the pope’s statements were indirectly benefiting Iran and making the world “less safe.” He suggested that the pontiff’s emphasis on humane treatment of migrants and calls for restraint in conflict signaled indifference toward the threat of Tehran acquiring nuclear weapons.
“The pope would rather talk about the fact that it’s OK for Iran to have a nuclear weapon,” Trump said, adding that such a stance could endanger millions, including Catholic communities worldwide.
There is no record of Pope Leo XIV supporting nuclear proliferation. The Vatican has consistently opposed nuclear weapons and advocated for diplomatic solutions. Responding to the remarks, the pope rejected Trump’s claims, saying the Catholic Church has long spoken out against nuclear arms.
“There is no doubt about that,” he told reporters, reiterating that his calls for peace in the ongoing conflict involving Iran are rooted in longstanding church teachings. He added that his mission is to promote the Gospel and encourage dialogue, not to engage in political disputes.
The exchange comes ahead of a planned visit to the Vatican by US Secretary of State Marco Rubio, who is expected to meet senior church officials in what had been seen as an effort to maintain stable relations. Rubio, a practicing Catholic, defended Trump’s position, arguing that concerns over Iran’s nuclear ambitions are legitimate and widely shared.
Tensions have also spilled into Italian politics. Prime Minister Giorgia Meloni, a close ally of Trump, has expressed unease over the president’s remarks about the pope. Italy’s Foreign Minister Antonio Tajani described the comments as unhelpful and inappropriate, stressing support for the pope’s message of peace and dialogue.
“I reaffirm my support for every action and word of Pope Leo,” Tajani said, adding that Italy remains committed to diplomatic efforts aimed at stability in conflict zones.
Rubio is also expected to meet Meloni and Tajani during his visit, as broader discussions continue on security, diplomacy and cooperation between the United States and its European partners.
The dispute highlights growing friction between political and religious leaders over how to address rising global tensions, particularly in the Middle East, where the conflict involving Iran continues to shape international debate.
