Abstract
The purpose of the article is to provide an integrated analysis of the strategic approaches, instruments, and institutional arrangements of cognitive countermeasures employed by Western states and international organizations to neutralize Russian information influence during 2022–2025. The study covers the diplomatic, information-analytical, technological, and societal dimensions of the West’s response to Russian influence operations. The methodological framework is based on structural-functional, comparative political, and information-analytical approaches, as well as content analysis of official documents, reports, digital platform data, and studies produced by NATO, the European Union, the G7, the Hybrid CoE, and independent research institutions. The article examines the evolution of strategic communications, the practice of pre-emptive intelligence declassification, the development of the OSINT ecosystem and fact-checking, sanctions-based public diplomacy, and technical tools for detecting and countering disinformation. Special attention is given to emerging threats associated with the use of generative AI in FIMI operations and to the responses of Western institutions to these challenges. The scientific novelty of the study lies in its integrated examination of Western cognitive countermeasures as a layered system encompassing diplomacy, digital security, algorithmic monitoring, artificial intelligence, fact-checking, and civic mobilization. Conclusions. During 2022–2025, Western approaches to cognitive countermeasures became substantially institutionalized and developed into a core element of security policy. A transition occurred from fragmented responses to a broad model integrating intelligence declassification, rapid debunking of hostile narratives, sanctions-based pressure, regulation of digital platforms, and the development of common strategic communication standards. Coordinated efforts by governments, supranational institutions, private companies, and civil society created a multi-layered deterrence ecosystem that significantly limited the effectiveness of Russian FIMI operations across the transatlantic space and in Ukraine. OSINT communities, automated manipulation detection tools, increasing media literacy, and the establishment of specialized centres for countering hybrid threats played an important role in this process. However, the current framework of countermeasures remains incomplete and still needs further refinement. The spread of generative AI, the emergence of high-quality deepfakes, circumvention mechanisms within the information ecosystems of the Global South, and the persistence of vulnerable audiences within Western societies create new challenges. Russian influence operations continue to adapt by combining social, political, and technological instruments while seeking to exploit internal crises within democratic states. Under these conditions, Western institutions require anticipatory planning, stronger regulatory frameworks, the integration of AI into protection and monitoring systems, and enhanced societal resilience through education, strategic communication, and cross-sectoral cooperation. Cognitive countermeasures are becoming a long-term, multidimensional, and technologically sophisticated component of contemporary security policy that requires the continuous refinement of approaches.
