With fear “the driving force” in the current global climate, nations must recommit to nuclear disarmament and the regulation of artificial intelligence, said Archbishop Gabriele Caccia, the Holy See’s permanent observer to the United Nations.
The archbishop shared his thoughts in a statement he delivered to the UN Disarmament Commission 8 April in New York, restating the Holy See’s call to all nations to “overcome the fallacy of nuclear deterrence” and “to accede to the Treaty on the Prohibition of Nuclear Weapons.”
The regulation of AI, which has increasingly transformed the defense industry, is also crucial, said the archbishop.
He cited the “multiple challenges posed by the use of emerging technologies, including artificial intelligence,” noting that their “increasing weaponisation could pose further existential risks.”

Archbishop Caccia surveyed the broader context for his calls to action, noting the global rise of conflicts and instability, and the increased investment in defense and deterrence.
However, nuclear proliferation, along with other weapons of mass destruction, “multiplies risks and offers only the illusion of peace,” while obscuring “the true path to peace,” said Archbishop Caccia.
