The exercise of New Public Diplomacy as a communication strategy in security and national defence issues within the EU: The case of Greece

The objective of this dissertation is to investigate the application of New Public Diplomacy as a strategic communication tool in matters of security and defense within the European Union, with a particular emphasis on the case of Greece. The study begins with a comprehensive analysis of the evolution of Public Diplomacy, tracing its trajectory from its traditional form to its contemporary, more interactive and multidimensional iteration. It then examines the implementation of New Public Diplomacy within the institutional framework of the European Union, through a critical exploration of relevant examples, instruments, actors, and initiatives. Subsequently, the research delves into the ways in which this form of diplomacy is practiced by Greek governmental actors, as well as through Greece’s participation in European programs and cooperative actions. A holistic analysis is presented, grounded in the methodologies of New Public Diplomacy, and supported by official statements, intergovernmental collaborations, and diplomatic practices both within and beyond the EU context. Furthermore, the study identifies and assesses key challenges and developments, both within the broader structure of the European Union and within the national context of Greece. Finally, it addresses future challenges and emerging issues, offering forward-looking proposals and constructive solutions aimed at fostering effective responses, serving not only the interests of Greece, but also contributing to the collective strategic coherence of the EU and its member states.
