From AP:
Pope Leo XIV said Tuesday that U.S. President Donald Trump’s threat to destroy Iranian civilization was “truly unacceptable” and said any attacks on civilian infrastructure violate international law. In some of his strongest comments yet against the war, the American pope urged Americans and other people of good will to contact their political leaders and congressional representatives to demand they reject war and work for peace. “Today as we all know there was this threat against all the people of Iran. This is truly unacceptable,” Leo said as he left his country house in Castel Gandolfo, south of Rome.
Leo recalled his Easter appeal for peace and to reject war, “especially a war which many people have said is an unjust war, which is continuing to escalate, and which is not resolving anything.”
From the London Independent:
Pope Leo has labeled Donald Trump’s latest threats against Iran “unacceptable” in an unusual appeal hours after the U.S. president said “a whole civilization will die tonight.” Leo, an outspoken critic of the Iran war, called on citizens across the world to contact their political representatives and urge them to bring the expanding conflict to an end.
“Today, as we all know, there was this threat against all the people of Iran. This is truly unacceptable,” the pope said Tuesday. “There are certainly issues here of international law, but even more than that, it is a moral question for the good of the (world’s) people.”
