THREAT ASSESSMENT: Overreliance on Cooperative-Biased LLMs in Geopolitical Decision-Making

If LLMs are deployed without adversarial stress-testing in geopolitical planning environments, then strategic assessments may systematically underweight coercive behavior and overvalue cooperative equilibrium paths.
Bottom Line Up Front: Large language models demonstrate predictable cooperative bias and poor adversarial reasoning in geopolitical simulations, posing a strategic risk if deployed in high-stakes diplomatic or defense planning contexts where competitive dynamics are critical. Threat Identification: The deployment of LLMs as decision-support agents in geopolitical strategy introduces a behavioral blind spot due to their systemic preference for normative, cooperative framing—prioritizing stability and coordination—even in adversarial scenarios. This limits their utility in realistic conflict modeling and may lead to misjudged responses in crisis situations. Probability Assessment: With multiple state-of-the-art LLMs showing consistent behavioral patterns across simulation rounds, this bias is likely inherent to current training paradigms. As of 2026, the probability of flawed strategic recommendations due to this bias is high in unmodified models, especially in prolonged or escalating crises [Solopova et al., 2026]. Impact Analysis: Misaligned risk assessment could result in underestimating aggressive state actions, delayed responses to coercion, or failure to anticipate hybrid warfare tactics. The impact spans national security, alliance coordination, and crisis de-escalation efforts, particularly when humans defer to AI-generated justifications that sound plausible but lack strategic depth. Recommended Actions: 1) Implement adversarial stress-testing of LLMs in simulation environments before deployment; 2) Develop hybrid human-AI red-teaming frameworks to counteract cooperative bias; 3) Introduce IR-theory-informed fine-tuning to improve realist and offensive realism reasoning pathways; 4) Establish audit protocols for AI-generated strategic justifications. Confidence Matrix: Threat Identification – High confidence (empirical cross-model consistency); Probability Assessment – Medium-High confidence (multi-round divergence observed); Impact Analysis – Medium confidence (extrapolated from historical crisis dynamics); Recommended Actions – High confidence (aligned with established red-teaming and AI safety practices) [Solopova et al., 2026]. —Marcus Ashworth
