Pope Leo Calls for Global De-escalation on First Anniversary, Following Meeting with U.S. Secretary of State Rubio

Pope Leo XIV, the first U.S. pope and former Cardinal Robert Prevost who spent decades as a missionary in Peru, marked his first anniversary as head of the Catholic Church on May 8, 2026 with visits to Pompei and Naples, Italy, calling on world leaders to reduce global tensions and turn away from violence. The anniversary appeal came one day after Pope Leo met with U.S. Secretary of State Marco Rubio at the Vatican in an atmosphere of unprecedented tension, with both parties pledging to improve bilateral relations after U.S. President Donald Trump repeatedly disparaged the pope on social media for criticizing the Iran war. Pope Leo, who kept a low profile for his first 10 months, has recently spoken forcefully against war and the arms trade, urging people not to become accustomed to images of death and praising Naples groups welcoming Gazan refugees.
