Pope Leo XIV has made a series of appeals for global peace since his election, focusing on the ongoing conflicts in Ukraine and Gaza, and addressing the challenges of modern technology. In his initial public appearances, including addresses from the balcony of St. Peter's Basilica, he has called for an end to war and promoted humanitarian efforts.

Echoing sentiments previously expressed by Pope Francis, Leo XIV has highlighted the severity of the current global situation, referring to it as a "third world war in tatters." He emphasized the need to avoid further global catastrophes by referencing the 80th anniversary of the end of World War II, a conflict that resulted in over 60 million deaths. He urged world leaders to prioritize peace and end the cycle of violence.

Specifically addressing the conflict in Ukraine, Pope Leo XIV conveyed his deep concern for the suffering of the Ukrainian people and called for a "genuine, just, and lasting peace." He also appealed for the release of prisoners and the reunification of families affected by the war.

The Pope expressed profound sorrow over the crisis in Gaza, demanding an immediate ceasefire and the provision of humanitarian aid to the exhausted civilian population. He also insisted on the release of all hostages.

In a more optimistic note, Pope Leo XIV welcomed the recent ceasefire announcement between India and Pakistan, expressing hope that upcoming negotiations would lead to a lasting agreement. He also touched on the broader issue of global conflicts, entrusting his appeals to Mary, Queen of Peace, for divine intervention.

Addressing the cardinals who elected him, Pope Leo XIV acknowledged the challenges posed by emerging technologies, particularly Artificial Intelligence (AI), to human dignity, justice, and labor. He stressed the importance of the Catholic Church taking a leading role in facing these threats and defending workers' rights.

During his first mass, Pope Leo XIV pledged to align himself with "ordinary people" and called for selfless missionary outreach to heal societal wounds. His formal installation mass is scheduled for May 18.
