Serena Giusti, in the book “Disinformation and Foreign Policy” published by Vita e Pensiero Editrice, examines the use of disinformation in foreign policy, analyzing how manipulation is used by States and other entities to influence the external environment and achieve objectives specific. The role of disinformation has evolved thanks to digital platforms, which allow anyone to create manipulated content and spread it globally anonymously. The advent of digital platforms has amplified the potential for the use of disinformation, as demonstrated by Russian attacks in the 2016 US elections and the 2022 invasion of Ukraine. The book highlights how disinformation is not just a propaganda tool, but it can become part of a broader strategy, even connection to hybrid warfare. Some tactical interventions can transform online conflicts into offline conflicts and even escalate into traditional conflicts.
