Artificial intelligence is accelerating decision cycles in combat and eroding human control, the head of the UN’s disarmament research institute warned, urging states to draw a “moral red line” against machines selecting and killing people. UNIDIR Director Robin Geiss said AI-driven systems—from intelligence parsing to autonomous drones—are speeding target engagement while remaining opaque, heightening the risk of error, miscalculation and unintended escalation, including in the nuclear domain. Despite geopolitical frictions, he noted a convergence of concern, citing a U.S. proposal for an AI incident-notification mechanism with China and growing support for tighter rules and a legally binding treaty on lethal autonomous weapons. UNIDIR will launch a new UN-based forum to craft voluntary industry guidelines, develop a shared “AI security lexicon,” and address non-state actors’ misuse—an attempt to build multilateral guardrails before adoption outpaces governance.
