Algorithmic invasions: How information warfare threatens NATO's eastern  flank – NATO Review – INSIGHT EU MONITORING

Modern warfare is no longer confined to physical battlespaces; it increasingly unfolds in the digital domain where information flows shape perceptions, morale, and legitimacy. Social media platforms have become central arenas in this contest, not simply because they disseminate information quickly, but because their algorithmic architectures amplify certain messages over others. The logic of recommendation systems, trending algorithms, and engagement-driven ranking means that narratives can spread virally, reaching audiences across the globe in seconds. For states and non-state actors alike, this creates opportunities to influence perceptions, mobilize support, and disrupt adversary cohesion without firing a shot. Information warfare has always been part of conflict, but in the algorithmic age it acquires new characteristics: speed, scale, and automation. Platforms designed for commercial engagement now function as de facto battlespaces where narratives compete for dominance, shaping both domestic resilience and international opinion. The outcome of wars is no longer determined solely by what happens on the ground, but also by who wins the contest of legitimacy in the algorithmic sphere.
