AI and the New Age of Bioweapons

Foreign Affairs  |  Elizabeth Sherwood-Randall

United States defense posture faces a critical vulnerability as the integration of artificial intelligence, advanced computing, and synthetic biology enables non-state actors and rogue entities to design and manufacture enhanced dual-use pathogens. Emerging technologies like generative biological models and automated cloud laboratories have drastically lowered technical barriers to weaponizing biological agents, rendering traditional nuclear deterrence models obsolete against non-state adversaries.

The rapid democratization of tools such as CRISPR and automated DNA synthesis allows actors with minimal specialized training to bypass safety protocols, enabling anonymous ordering and scaling of dangerous viral strains like H5N1 avian influenza. In response to these evolving threats, Washington must pivot toward a posture of deterrence by resilience, focusing on comprehensive biological surveillance systems, rapid genetic attribution capabilities, and scalable biomanufacturing protocols. Establishing integrated early-warning frameworks alongside pre-negotiated pharmaceutical production capacity aims to neutralize the strategic impact of biological attacks, thereby disincentivizing potential perpetrators from attempting targeted disruption against critical agricultural and human assets.

Comment

The reliance on strategic ambiguity within the 2022 Nuclear Posture Review demonstrates an expanding mismatch between Cold War deterrence frameworks and democratised biomanufacturing capabilities. Threatening high-yield retaliation against non-state actors operating through obfuscated digital workflows and contract cloud laboratories lacks operational credibility. When viral design occurs in computational environments and physical synthesis is outsourced anonymously, traditional nuclear counter-value targeting provides zero coercive leverage.

This posture failure forces counter-proliferation doctrine to shift from threat-based deterrence to functional operational containment. Without identifiable state infrastructure to hold at risk, nuclear deterrence as articulated in the 2022 Nuclear Posture Review ceases to function against anonymous cloud-synthesis pipelines.

Strategic Question for Discussion

How does the explicit ambiguity regarding non-nuclear strategic threats in the 2022 Nuclear Posture Review alter the credibility of extended deterrence when facing decentralized, non-state bioweapon threats?

The available evidence points toward a structural breakdown in threat-based deterrence when applied to non-state entities utilizing distributed synthesis networks. The 2022 Nuclear Posture Review assumed state-level actors with clear attribution pathways, whereas decentralized bioweapon pipelines effectively decouple offensive capability from geographic or institutional targets. Consequently, extended deterrence loses coercive friction, shifting the primary burden of strategic stability entirely onto defensive containment and bio-surveillance infrastructure.
