The growing interconnection of technology and politics and the enactment of particular political goals (technopolitics) has been closely articulated with emotions and the building of foreign policy narratives. In the current context of change in the communication paradigm, global and disintermediated, bringing together in the same digital space distinct actors, and having wide diffusion and reach, the challenges to international politics are diverse. Digital and media literacy are, in this regard, key to address the implications of these changes, avoiding the spreading of disinformation, fake news and distorted practices that might have profound effects at societal and political level. In this context, this paper aims at providing a basis for understanding the emerging and increasingly clear connection between political communication, polarization, disinformation, and emotions in social networks and digital literacy as a central factor explaining misuse or alleviating deficiencies, on the one hand, and how this context is affecting the reconfiguration of international relations and politics, on the other hand. The case of the war in Ukraine is illustrative of these trends and dynamics.
