A public dispute between Pope Leo and former US President Donald Trump has escalated in recent days, revealing a sharp deterioration in relations between the Vatican and Washington. The conflict began after Pope Leo publicly criticized US-Israeli actions in Iran, prompting a strong rebuke from Trump on social media.
A History of Diplomatic Tension
The current clash echoes past diplomatic strains between the Vatican and the White House, as recalled by Walter Colantini, an optician in Borgo Pio who has served multiple popes. Colantini specifically referenced tensions during the 1991 Gulf War. However, he stated that the current rupture provoked by Trump is unprecedented. “Trump is off the wall, he has no limits,” Colantini said.
Trump’s Response and Wider Fallout
Trump responded to Pope Leo’s criticism with a social media tirade, calling the pontiff “weak on crime” and “terrible on foreign policy,” and falsely claiming Leo was elected pope due to Trump’s own political influence. Trump also shared and later deleted an AI-generated image depicting himself as Jesus Christ. Following Trump’s outburst, US Vice President JD Vance urged the Vatican to “stick to morality” and allow the president to dictate US public policy.
International Reactions
The dispute has drawn reactions from across the political spectrum. While some US Catholics expressed support for Trump, believing he is “making the world safe,” many European leaders have voiced solidarity with Pope Leo. Italy’s Prime Minister Giorgia Meloni called Trump’s remarks “unacceptable,” prompting a further rebuke from Trump himself.
A Shift in Papal Tone
Pope Leo is described as more direct and assertive than his predecessor, Pope Francis, who was known for his humble demeanor. Since his election, Leo has moved from urging ceasefires to more forcefully condemning the US-Israeli war in Iran and the broader conflict in the Middle East, particularly following Trump’s threat to destroy “a whole civilisation” in Iran.
What Happens Next?
Trump will continue his attacks on Pope Leo, further escalating the conflict. The Vatican may respond with further condemnations, or attempt to de-escalate the situation through diplomatic channels. Depending on the outcome of the US presidential election, the future of US-Vatican relations remains uncertain. It is also likely that the dispute will continue to fuel debate among Catholics worldwide regarding the role of the Church in political affairs.
