1 / 7The clash between Donald Trump and Pope Leo XIV stands out for its unusually public and adversarial tone. Trump has called the first American pontiff “weak” and “very liberal” over his criticism of the US-Israel war in Iran. While tensions between leaders and the Vatican are common, they are typically handled quietly through diplomacy. Even Trump’s earlier friction with Pope Francis in 2016 over immigration didn’t reach this level, making this standoff a rare, openly confrontational break from precedent. (Image: Reuters)
