US and China experts urge international ban on AI control of nuclear weapons.
A bipartisan group of leading US and Chinese artificial intelligence and nuclear security experts has jointly called for a binding international agreement to prohibit any AI system from having autonomous control over nuclear weapons. In a new report, they argue that the risk of accidental escalation, miscalculation, and loss of human oversight is too high to allow machines to make launch decisions.
The experts warn that even conventional conflicts could spiral into a nuclear exchange if AI is allowed to manage early warning systems or command-and-control networks. The report recommends a clear, verifiable ban on “the use of AI for nuclear command, control, communications, and early warning systems where it could enable or increase the speed of nuclear decision-making.”
Why AI and nuclear weapons do not mix
AI systems are inherently brittle and unpredictable. They can be tricked by adversarial inputs, suffer from hidden biases, and fail in ways that are hard to detect until it is too late.
- Speed versus deliberation: AI could compress decision timelines from hours to minutes, removing time for diplomatic cooling-off or double-checking.
- False alarm amplification: An AI misreading a radar anomaly might trigger a cascade of automated counter-measures, turning a sensor glitch into a nuclear crisis.
- Escalation dynamics: If one side deploys AI-enabled early warning, the other side may feel forced to also automate, creating a destabilizing arms race in software.
The report stresses that human control must remain meaningful and not just a “button in the loop.” A human who is overwhelmed with machine-generated recommendations can no longer exercise true judgment.
What the proposed rules would look like
The experts outline several concrete provisions for a future treaty:
- No AI in nuclear launch decisions: Any system that could initiate or authorize a nuclear strike must have a human in full control.
- No AI in critical early warning: AI can assist analysis but should not be the sole source of a launch order trigger.
- Verification mechanisms: Nations would need to share enough information to allow confidence that AI is not being inserted into command chains.
- Transparency obligations: Countries should publish their policies on AI use in military nuclear infrastructure.
- Joint exercises: Regular tabletop simulations involving both US and Chinese officials to test crisis stability under AI stress.
“The goal is not to ban all military AI — that is unrealistic — but to draw a bright line around nuclear weapons. The stakes are existential, and the margin for error is zero.”

The political context
The calls come at a time when both the US and China are investing heavily in AI for defense. The Pentagon’s new “Replicator” initiative and China’s accelerating drone and AI programs have raised alarms among arms control specialists.
Nuclear doctrine in both countries has traditionally prized human judgment at the top. But as sensors become more numerous and data streams more massive, there is growing bureaucratic pressure to automate the filtering process. The report warns that such incremental automation could eventually lead to de facto machine control.
The experts recommend that the ban be negotiated through existing arms control forums, possibly as an add-on to the New START treaty or as a standalone arrangement. They acknowledge that verification is difficult but argue that the risk of cheating is far lower than the risk of inaction.
Background: How close are we to AI control?
No known military currently allows AI to decide on nuclear strikes. However, several nations use AI for early warning analysis, target selection assistance, and logistics. The divide between “assist” and “control” is dangerously fuzzy.
- United States: The semi-autonomous “Launch on Warning” protocols rely on human confirmation, but AI sensor fusion is already used to reduce false alarms.
- China: Beijing has not publicly disclosed its AI–nuclear integration, but official statements emphasize absolute party control, which implies a human chain.
- Russia: Moscow has hinted at developing AI-enabled nuclear command systems, though no verified deployment exists.
The report highlights that a ban now, while technology is still maturing, is far easier than trying to reverse engineer control after systems are deployed.
A rare bipartisan and bilateral consensus
This initiative is notable because it brings together experts from two countries often at odds over trade, technology, and territory. The group includes former military officers, computer scientists, and diplomats from both sides.
They argue that nuclear risk is a shared challenge that transcends political rivalry. If a crisis or miscalculation occurs, it will not discriminate between Washington and Beijing.
“We have managed to avoid nuclear war for 80 years through mutual restraint and human judgment. AI should not be allowed to become the new wild card.”

The next step is to present the recommendations to the UN Conference on Disarmament and to the national security councils in both capitals. The experts hope that the gravity of the subject will overcome partisan gridlock.
