Building a Multilateral Cognitive Warfare Defense Network: A Collaborative Framework for the United States, Japan, and Taiwan

This Atlantic Council report makes the case for a structured trilateral framework to counter cognitive warfare in the Indo-Pacific, centred on the US–Japan–Taiwan triangle. The framing is explicitly operational: the report moves quickly past the definitional debates that characterise much academic work on cognitive warfare to focus on the institutional architecture and information-sharing arrangements that a credible multilateral defence posture would require. The choice of partners reflects a strategic logic — each of the three faces distinct but overlapping threat profiles from China's information operations, and each has developed institutional responses that the others could learn from.

The report's value lies in its willingness to be specific about what a collaborative framework would actually entail: joint threat assessment, coordinated early warning, shared analytical tools, and agreed thresholds for escalation. Whether the political conditions exist for this level of integration is a separate question — one the report largely sets aside — but the operational blueprint it offers is a useful contribution to a policy debate that often remains at the level of aspiration. Analysts working on Indo-Pacific security architecture or multilateral counter-FIMI design will find it a substantive starting point.
