Vice President JD Vance stood before 931 newly commissioned officers at Falcon Stadium and delivered a blunt warning about the future of American warfare: the country must never hand the power to kill to a machine.

Speaking at the U.S. Air Force Academy commencement in Colorado Springs on May 28, Vance told graduates that artificial intelligence may reshape every corner of military life, but that moral judgment in combat cannot be automated. His remarks tracked closely with Pope Leo XIV's recently released encyclical Magnifica Humanitas, which called on humanity "not to outsource the most important decisions to digital technology."

The overlap was not accidental. And the speech amounted to the most detailed public statement yet from a senior administration official on where the line should fall between AI capability and human conscience in war.

A Marine veteran's case for human judgment

Vance, himself a Marine Corps veteran, told the graduates that of all the ways AI could reshape American life, the labor market, resource distribution, social interaction, one concern towers above the rest.

"The thing I worry about most with AI is how it will change warfare."

That single sentence set the frame for a speech that moved between strategic realism and moral philosophy. Vance did not dismiss AI's battlefield utility. He acknowledged the technology's power. But he drew a hard boundary.

"And if the warfare of the future is to live up to the moral values of our ancestors, decisions over life and death must be made by humans and not machines."

The vice president urged the new officers to embrace technology without surrendering to it. "Use technology to make you better, but never submit to it," he said. He called the graduates "the masters of warfare" and told them their minds and hearts are "the opposite of artificial."

It was a pointed distinction. In an era when defense contractors and Pentagon planners are racing to integrate autonomous systems into every domain, air, space, cyber, sea, Vance planted a flag on the side of human primacy.

Where Vance and the Pope agree, and where they don't

The parallels with Magnifica Humanitas were unmistakable. Pope Leo XIV's first encyclical warned that AI systems, however impressive, "do not undergo experiences, do not possess a body, do not feel joy or pain, do not mature through relationships and do not know from within what love, work, friendship or responsibility mean." The Pope called for "moral and social discernment that safeguards the primacy of the human person."

Vance has been tracking the encyclical closely. He previously called the forthcoming document a "very, very important" text, a notable endorsement from a vice president who converted to Catholicism and has spoken openly about faith's role in public life.

But the alignment has limits. Pope Leo's encyclical went further than AI, wading into just war theory and declaring it "outdated." The Pope stated that "force, violence and weapons reflects a relational poverty that always has disastrous consequences for civilian populations" and argued that "dialogue, diplomacy and forgiveness" are superior tools for resolving conflict.

Those comments, particularly when the Pope implied the United States was not waging a just war in Iran, drew a sharp response from President Trump and put the administration in an awkward position. Vance addressed the tension weeks before the commencement, saying the Pope should exercise caution on theological matters just as a vice president should be careful on public policy.

"In the same way that it's important for the vice president of the United States to be careful when I talk about matters of public policy, I think it's very, very important for the pope to be careful when he talks about matters of theology."

At the Air Force Academy, Vance did not retreat from just war doctrine. He embraced it, and framed it as a distinctly American burden. What "makes Americans unique," he told the graduates, "is that we wage war justly." He called that responsibility an "incredible burden" but said the nation entrusts it to them "with full confidence."

That is a direct rebuttal to the Pope's suggestion that just war theory has outlived its usefulness. Vance accepted the encyclical's AI framework while rejecting its pacifist implications, a deft theological and political maneuver that let him honor the Pope's moral authority on technology without conceding ground on national defense.

931 officers and a five-year commitment

The ceremony itself was a reminder that these debates are not abstract. The 931 graduates who walked across the stage will enter the Air Force or Space Force and serve a minimum of five years. Newsmax reported that 805 of the new officers were assigned to the Air Force and 94 to the Space Force.

They will deploy into a military landscape where autonomous drones, AI-driven targeting systems, and machine-speed cyber operations are no longer theoretical. The question Vance raised, who pulls the trigger, a person or a processor, will follow them into every assignment.

Vance framed the graduates as the answer to that question. "You're the ones who ensure that our lethality in war, which is amazing and necessary... also coexists with our heart and with our conscience," he said.

The vice president's speech comes during a period of intense diplomatic and military activity for the administration. Vance has been closely involved in White House deliberations as Iran ceasefire talks have stalled, giving his remarks on warfare and moral judgment an immediate, operational edge.

The Washington Examiner noted that Vance continued a tradition of vice presidents addressing the Academy, following Kamala Harris in 2024. National Review documented the ceremony, showing Vance saluting cadets alongside Air Force Secretary Troy Meink and Academy Superintendent Lt. Gen. Tony D. Bauernfeind.

The harder question ahead

What Vance did not provide, and what the encyclical also largely avoids, is a concrete policy framework for keeping humans in the loop as AI accelerates beyond human reaction time. The speech was philosophical, not legislative. No specific regulations, executive orders, or Pentagon directives were announced.

That gap matters. America's adversaries are not waiting for a moral consensus before deploying autonomous weapons. China has invested heavily in AI-enabled military systems. Russia has tested autonomous combat drones. The pressure to match those capabilities will only grow, and "never submit to it" will eventually need to become something more specific than a commencement applause line.

Vance, who has been building a public profile that blends conservative populism with Catholic intellectual tradition, seems to understand the stakes. His recently announced faith memoir and his willingness to engage seriously with papal teaching suggest this is not a one-off speech but the beginning of a longer argument.

The encyclical acknowledged that AI systems "often surpass human intelligence in speed and computational capacity, offering tangible benefits across many fields." But Pope Leo insisted those systems "do not have a moral conscience, since they do not judge good and evil, grasp the ultimate meaning of situations, or bear responsibility for consequences." They may "simulate empathy and understanding," but "they do not understand what they produce."

Vance's contribution was to take that insight out of the Vatican and plant it on a parade ground in Colorado, in front of young officers who will spend the next decade deciding how much authority to hand to the machines they operate.

The New York Post reported that Vance's warning about AI and warfare was the centerpiece of the address, a signal that the administration views the question not as a sideshow but as a defining challenge.

Right message, right audience

There is something fitting about delivering this speech to military officers rather than to a tech conference or a Senate hearing room. Silicon Valley builds the tools. Congress writes the checks. But the men and women in uniform are the ones who will face the moral weight of pulling, or not pulling, a trigger that a machine says is justified.

Vance told them the burden is theirs, and that the nation trusts them to carry it. That is the right message. The harder work, writing the rules that keep a human hand on the switch when the algorithms get faster and the wars get messier, still lies ahead.

Machines can process data. They cannot bear responsibility. Any country that forgets the difference will eventually wish it hadn't.
