As a critical element of a multidimensional political warfare scheme, disinformation represents a serious challenge for European democracies. Convinced that it faces an existential threat from the West, Russia aims to turn some key features of democracy, such as the free flow of information and the open and plural nature of European societies, into a strategic vulnerability. The internet, especially through social networks, offers open access to the heart of liberal democracies. This is where the Kremlin deploys its information warfare with the aim of weakening NATO and the EU in general. Spain, a committed member of both and also a platform for reaching the Spanish-speaking world of Latin America, is no exception to this rule.
