Castel Gandolfo, Italy, Dec 9, 2025 / 15:15 pm (CNA).

Pope Leo XIV said President Donald Trump’s plan to end Russia’s war against Ukraine threatens to break apart the alliance between Europe and the United States.

Asked by reporters Dec. 9 to comment on the initiative’s fairness, the pope said, “I would rather not comment on that. I haven’t read the whole thing. Unfortunately, some parts I have seen make a huge change in what was for many years a true alliance between the EU and U.S.”

The pope commented to reporters after meeting with Ukrainian President Volodymyr Zelensky at Castel Gandolfo. 

Pope Leo said, “The remarks [by Trump] that were made about Europe recently are, I think, trying to break apart what I think is an important alliance today and in the future. It’s a program that President Trump and his advisers put together, and he’s the president of the U.S. And he has a right to do that.”

The Holy Father called for continued dialogue to seek a “just and lasting peace” in Ukraine during the meeting with Zelensky on Tuesday, according to the Vatican.

The pair also discussed the question of prisoners of war and the urgent need to assure the return of Ukrainian children to their families. According to the Vatican, the Holy See will continue its efforts to do that — including “through the efforts of the Special envoy of the Holy Father for humanitarian issues in Ukraine,” Cardinal Matteo Zuppi said, and to ensure the release of prisoners of war. 

Responding to a question from EWTN News, the pope said that progress on the repatriation of abducted Ukrainian children was “very slow, unfortunately,” but he declined to comment further on the matter.

The Vatican has mediated between Kyiv and Moscow on the issue of the children’s return. Zelensky wrote on X, “I informed the Pope about diplomatic efforts with the United States to achieve peace. We discussed further actions and the Vatican’s mediation aimed at returning our children abducted by Russia,” Zelensky wrote on X.

In a statement published by the Vatican after the meeting at Castel Gandolfo, the pope “reiterated the need for the continuation of dialogue and expressed his urgent desire that the current diplomatic initiatives bring about a just and lasting peace.”

Following the private audience, Zelensky expressed his “profound gratitude” to Pope Leo XIV for the Holy See’s constant support for the Ukrainian people.
