Marking the International Day Against Nuclear Tests on September 1, the Holy See renewed its firm call to end nuclear testing and advance toward a nuclear-free world. Speaking at a High-level Plenary Meeting at the United Nations in New York, Monsignor Robert D. Murphy—Counselor and Chargé d’Affaires at the Holy See’s Permanent Observer Mission—emphasized that nuclear testing leaves long-lasting physical, psychological, social, and environmental consequences that unfairly impact indigenous peoples, women, children, and future generations.
Citing data from Norwegian People’s Aid (NPA), the address highlighted that over 2,000 atmospheric and underground nuclear tests occurred across 15 countries between 1945 and 2017. Survivors and their descendants face increased rates of cancer, cardiovascular disease, congenital anomalies, and psychological trauma. Monsignor Murphy stressed that this widespread suffering should reinforce the global conviction that lasting peace cannot be built through ever-more destructive weapons or a renewed reliance on nuclear deterrence.
In light of rising nuclear rhetoric and threats to international norms, the Holy See reaffirmed that bringing the Comprehensive Nuclear-Test-Ban Treaty (CTBT) into force remains an urgent priority. Until the treaty enters into full effect, Monsignor Murphy emphasized that observing existing moratoria on nuclear testing is essential to preserving key international security achievements. He also commended the work of the CTBT Organization’s Preparatory Commission and its International Monitoring System as a stellar example of international scientific collaboration.
Ultimately, the Holy See reiterated its support for both the Treaty on the Non-Proliferation of Nuclear Weapons and the Treaty on the Prohibition of Nuclear Weapons, describing them as mutually reinforcing tools needed to achieve a nuclear-free world. Concluding his address, Monsignor Murphy urged world leaders to reject the logic of fear and instead embrace dialogue, disarmament, and a peace rooted in the shared dignity of the human family.
