Amid disagreement over the next steps in the Iran deal, US President Donald Trump has once again attacked Pope Leo XIV, this time in his hometown. On May 28, the Pope met with Chicago Mayor Brandon Johnson at the Vatican, who later posted on X to commemorate the occasion. "It was an honor to spend time with a magnificent man, His Holiness Pope Leo XIV", he wrote in one post, later adding that the "interfaith prayer in the Vatican was one of the most emotional and touching experiences" of his life. The White House resident picked up and commented on the remarks on the social networking site Truth, saying, "Someone should explain to the Pope that the mayor of Chicago is useless and Iran cannot have a nuclear weapon". The attack was aimed at both the Catholic Church's highest authority and Chicago, the third-largest city in the United States: "In my conversation with His Holiness Pope Leo XIV, I got to know an incredibly humble man, whose Chicago roots define the magnanimity of his leadership at this historic moment". These are the words that Mayor Johnson used to describe the Pontiff's role in this intricate geopolitical era, in which the president of the United States is the primary participant. This is not the first time Trump has attacked Leo for advocating for a peaceful resolution to the Middle East conflict: in April, he labeled the Pope "weak" on crime and "terrible" on foreign policy, and this month he declared that his actions were "putting many Catholics in danger". The mayor of Chicago then responded to the tycoon's latest attack late at night in Italy, saying, "The citizens of Chicago have had enough of Trump's blasphemous war in Iran" Someone should explain to the president that his bellicosity makes it more difficult for working families to make ends meet".
