Donald Trump isn't exactly known for keeping his thoughts on the Vatican to himself. But his latest claims about Pope Leo XIV and Iran’s nuclear ambitions have pushed the relationship between Washington and the Holy See to a breaking point. Just days before Secretary of State Marco Rubio's high-stakes visit to the Vatican on May 7, 2026, Trump doubled down on a narrative that has left many Catholics and foreign policy experts scratching their heads.
Trump basically told anyone who would listen that the first American-born Pope is "endangering a lot of Catholics" by allegedly supporting a nuclear-armed Iran. It's a bold claim. It's also one that flies in the face of everything the Vatican has actually said.
The claim that doesn't hold up
Trump's beef with the Pope isn't new, but it's getting weirder. In recent interviews, the President has repeatedly suggested that Pope Leo XIV "seemed to be saying" Iran should have nuclear weapons. During a chat with the Salem News Channel, Trump went as far as saying the Pope would "rather talk about the fact that it's okay for Iran to have a nuclear weapon."
If you're looking for where the Pope actually said that, don't hold your breath. You won't find it.
Leo XIV hasn't just avoided supporting nuclear weapons; he's spent a huge chunk of his eleven-month papacy calling for their total elimination. In fact, back in June 2025, after a series of strikes on Iranian enrichment facilities, Leo was pretty clear. He called for a "safer world, free from the nuclear threat." For the Vatican, nuclear weapons aren't a tool for peace—they’re an "irrational" deterrent based on fear.
Rubio's impossible job at the Vatican
Marco Rubio is a practicing Catholic, and he’s often the one sent in to clean up the mess after Trump’s rhetorical grenades. This trip is no different. Rubio is scheduled to meet the Pope on Thursday, and the official line from the State Department is that they’re there to discuss "mutual interests" and "religious freedom."
But we all know the real elephant in the room. Rubio is stuck between a President who wants a "message" delivered—that Iran cannot have nuclear weapons—and a Pope who thinks the U.S. approach to the conflict is making things worse.
Trump has been pushing a hardline military strategy, while Leo XIV has consistently slammed military escalation. The Pope’s stance is rooted in the Gospel, not a desire to see Iran go nuclear. He’s essentially arguing that you can’t bomb your way to a peaceful Middle East. Trump sees that as weakness.
Why the tension is boiling over now
This isn't just about Iran. The friction between Trump and Leo XIV has been building for months.
- Immigration: Trump previously called the Pope "soft on crime" regarding U.S. border policies.
- The "Doctor" Image: Tensions spiked after Trump shared (and then deleted) an AI-generated image of himself that looked a lot like Jesus. Trump later claimed it was just him dressed as a doctor. Nobody really bought that.
- NATO and Allies: Trump’s frustration has extended to Italian Prime Minister Giorgia Meloni, who actually sided with the Pope and criticized Trump’s comments.
Honestly, the real issue here is a fundamental disagreement on how the world should work. Trump believes in "peace through strength" and military dominance. Leo XIV believes in "peace through dialogue" and disarmament. When those two worldviews collide, you get the kind of social media firestorm we’ve seen over the last few weeks.
What to watch for during the visit
When Rubio walks into the Apostolic Palace, don't expect a joint statement that fixes everything. The Vatican has already signaled that Leo isn't "trying to debate the President," but he’s also not backing down. On a recent flight to Algeria, the Pope told reporters he has "no fear" of the Trump administration.
For Rubio, the goal is likely damage control. He needs to keep the door open with the Holy See while staying loyal to the man in the Oval Office. It’s a tightrope walk.
If you’re following this story, keep an eye on the official Vatican readouts after the meeting. Look for mentions of "sincere dialogue" or "fraternal encounter." That’s Vatican-speak for "we still disagree on everything, but we’re being polite about it." If the language is sharper, it means Rubio’s attempt at a "thaw" in relations didn't quite work.
The reality is that the Catholic Church’s opposition to nuclear weapons is a decades-old policy, not a partisan jab at the current White House. Whether Trump accepts that or keeps using it as a campaign talking point is the real question. For now, the "endangering Catholics" narrative seems more about domestic politics than actual Vatican diplomacy.
