During a recent flight to Spain, Pope Leo XIV declared that the war between the United States and Israel against Iran does not meet the criteria for a 'just war' as defined by Catholic doctrine. He highlighted that the concept of 'just war' is rooted in historical contexts that do not account for modern military technology capable of mass destruction. The Pope stated, 'There is no just war there,' emphasizing that the traditional doctrine is obsolete in today's warfare environment. He further described the conflict as 'unjust' and called for a reevaluation of how wars are justified. Additionally, the Pope addressed the ongoing military operations in southern Lebanon and expressed concern over the war in Ukraine, advocating for diplomatic efforts to resolve both situations. His remarks reflect a consistent stance against armed conflict and a commitment to peaceful negotiations as the preferred means of addressing international disputes. The Pope's comments drew criticism from former President Donald Trump, who labeled him as 'weak' on war matters, a critique the Pope dismissed, reaffirming his position on the need for peace.
