Challenges to national defence in contemporary geopolitical situation

The study focuses on an indicative analysis and critical evaluation of tools and methods used for fact-checking, which represent a key instrument in combating disinformation within the contemporary media environment. In the context of the spread of false or manipulative narratives, particularly through social media and online platforms, systematic fact-checking may be one of the tools for preserving information integrity and protecting the public from harmful content. The aim of the study is to formulate recommendations, based on a constructively critical mapping of the current situation, which can contribute to more effective management of the related agenda.

This paper examines how digital media discourse influences national security and institutional trust using UK-related data (39,760 mentions; reach 255.3 million) collected between November 2025 and April 2026. Applying AI-assisted media analytics, it identifies key risk patterns, including the dominance of negative sentiment, platform-driven amplification, and the transnational circulation of narratives. The findings show how these dynamics generate structural vulnerabilities for democratic institutions and complicate strategic communication. The study proposes a practical analytical framework for monitoring influence operations, enabling earlier detection of coordinated campaigns and supporting faster, evidence-based policy responses in complex digital information environments today.

By exploiting the potential of social media, disinformation has become an important element of warfare. The region of Central and Eastern Europe (CEE) is particularly vulnerable to disinformation, primarily from Russia. One of the reasons for Russia’s activities in this region’s infosphere is that most CEE countries are members of the European Union and the North Atlantic Treaty Organization (NATO). In this context, Russian disinformation activities aimed at the Three Seas Initiative (3SI) are particularly interesting. The image of the 3SI created in the media is crucial, for it translates into how the public understands, perceives and recalls this format of cooperation. The article aims to reconstruct the image of the 3SI in cases of Russian disinformation identified by the European External Action Service within the EUvsDisinfo project. The article’s methodology is based on a qualitative content analysis of disinformation cases identified by EUvsDisinfo. The article identifies four main frames of disinformation targeting the 3SI, showing that Russian disinformation is focused on undermining the credibility and integrity of this cooperation, both among Initiative countries and between them and their international partners.

The articles analyses the penetration of social media through personal use into daily life and the relation of this phenomenon to national security. A survey of Lithuanian higher-school students aged 18-29 was conducted according to quantitative research methodology. Young people actively use social networks for various purposes (personal, learning, work, recreation). Statistically, each individual, aged 18-29, has personal profiles on four social networking sites, yet most often does not adequately evaluate and link the use of social networks with possible national security threats and risk factors. Less than two-thirds of young people have heard something of possible threats and risk factors; however, the impact of social media on national security is not considered significant. Thus, it seems that young people lack information about real threats presented by social networks to both personal data storage and national security.
