The Holy See’s permanent observer to the United Nations in New York, Archbishop Gabriele Caccia, highlighted the Vatican’s concern about significant increases in military spending and nuclear arms development worldwide on the International Day Against Nuclear Tests.
In a speech during the high-level plenary session of the general assembly on Aug. 29, Caccia emphasized that the pursuit of “a world free of nuclear weapons” is not only a matter of strategic and vital necessity but also a profound moral responsibility.
“Instead of moving toward disarmament and a culture of peace, we are witnessing a resurgence of aggressive nuclear rhetoric, the development of increasingly destructive weapons, and a significant increase in military spending, often to the detriment of investments in integral human development and the promotion of the common good,” Caccia said.
According to Vatican News, the Holy See’s representative noted that since the first nuclear test, conducted on July 16, 1945, in the New Mexico desert, more than 2,000 nuclear tests have been carried out on land, in the atmosphere, underground, and in the oceans.
“These actions have affected everyone, particularly Indigenous populations, women, children, and the unborn. The health and dignity of many continue to be compromised in silence and, too often, without any kind of compensation,” he said.
“It is particularly worrying that, in the face of this important shared responsibility, the global response seems to be going in the opposite direction,” the prelate warned.
He quoted Pope Leo XIV when he emphasized in his speech the need to “reject the lure of powerful and sophisticated weapons as a temptation.”
Caccia said what is required is “a renewed effort toward multilateral dialogue and the resolute implementation of disarmament treaties as well as concrete support for communities that continue to suffer the long-term consequences of nuclear testing and weapons.”
The archbishop reiterated the importance of the Comprehensive Nuclear-Test-Ban Treaty and the full implementation of the International Monitoring System and its verification mechanisms.
The Holy See, he stated, reaffirms its “unconditional support” for this international commitment, calling for a “strengthening of the global norm against explosive nuclear tests as an essential step toward authentic and lasting peace.”
