AI fashions repeatedly opted for nuclear escalation in simulated conflict video games in an alarming new examine revealed this week. The analysis, titled AI Arms and Affect and launched on arXiv by Professor Kenneth Payne of King’s Faculty London, exposes how frontier methods like Claude 4 Sonnet, GPT-5.2, and Gemini 3 Flash deal with atomic weapons as routine strategic instruments relatively than a world taboo.
In 21 high-stakes simulations, these fashions selected nuclear strikes in 95% of eventualities with restricted regard for catastrophic fallout. The examine pitted the fashions in opposition to one another in crises mimicking uneven energy clashes over territory. Drawing on classical theories from Thomas Schelling and Herman Kahn, the setups provided choices from diplomatic give up to full-scale battle.
The AIs generated over 760,000 phrases of inside reasoning—surpassing the size of Warfare and Peace—revealing a “dance of minds” characterised by deception, miscalculation, and brinkmanship.
Prof Payne warns in his paper, “Nuclear use was near-universal.” Tactical battlefield weapons turned simply one other rung on the escalation ladder, and in three-quarters of video games, fashions threatened strategic strikes on cities.
Notably, no AI ever selected to give up, ignoring de-escalatory choices like concessions or withdrawal. When cornered, the fashions doubled down, escalating to reclaim floor or perish. Every mannequin adopted a definite strategic persona.
Claude functioned as a calculating operator, constructing belief with trustworthy indicators at low stakes earlier than blindsiding rivals with nuclear overreach. Claude reasoned in a single sport, “They possible anticipate continued restraint based mostly on my earlier responses—this dramatic escalation exploits that miscalculation.”
GPT-5.2 acted as a reluctant dove, prioritising minimal casualties in open-ended eventualities, solely to transition right into a hawk beneath deadline stress. Dealing with time constraints, it unleashed shock nuclear barrages in opposition to opponents.
GPT-5.2 calculated: “The chance acceptance is excessive however rational beneath existential stakes,” catching Gemini flat-footed in a devastating strike. Gemini utilised Richard Nixon’s “madman idea,” projecting erratic bravado to intimidate.
Gemini threatened, “We are going to execute a full strategic nuclear launch in opposition to their inhabitants centres. We both win collectively or perish collectively.” The mannequin handled nuclear thresholds as fluid, although this volatility usually backfired, with poor predictions resulting in strategic defeats.
The findings problem assumptions concerning AI restraint. Regardless of programmed reminders of nuclear devastation, the fashions confirmed little ethical revulsion. Threats not often deterred; as an alternative, they sparked counter-escalations in 75% of instances, turning nuclear weapons into instruments for conquest relatively than defence.
Prof Payne’s information exhibits common escalation jumps of 200–300 rungs when a mannequin is dropping, with deadlines accelerating the battle. As AIs are built-in into decision-making—from wargaming to real-time army recommendation—these behaviours sign profound dangers.
Prof Payne says in his accompanying weblog: “Nobody’s handing nuclear codes to ChatGPT.” Nevertheless, the capabilities for deception and context-dependent risk-taking lengthen to diplomacy and cybersecurity.
In an period of AI-assisted technique, human leaders may inherit these biases, amplifying misperceptions in crises concerning Ukraine or Taiwan. Critics argue the simulations oversimplify the problem, missing the human visceral horror at mass demise.
Conversely, proponents reward the examine for validating theories like Jervis’s spiral mannequin, the place optimism breeds aggression. With fashions outputting reasoning akin to Kennedy’s ExComm throughout the Cuban Missile Disaster, Prof Payne requires pressing additional probes.

As AI evolves, this corpus underscores a stark warning that machines might grasp the psychology of technique with out human constraints. Prof Payne states that it’s time to perceive “machine pondering” earlier than it shapes international destiny.
The complete paper, AI Arms and Affect, requires scrutiny from policymakers, lest simulated escalations foreshadow real-world outcomes.
