Through this project, we have many different aspects which we would like to address. The main objective of this project is to underline the soft power of the Erasmus+. Our project with the title "Cultural Diplomacy within the Erasmus+", will be a double activity of 2 actions (with 22 participants in the TC 1, 36 participants in the TC 2 of the project. The trained youth workers of the TC, will be responsible of planning, organising and disseminating the second action of the project, TC2 ): A1- Training Course in Athens, Greece A2- Training Course in Nea Kallikrateia, Greece The shift in the concept of security demands a revisiting of the concept of soft power. In this case, cultural diplomacy must be understood in terms of soft power and soft power must be understood in terms of capacity - capacity to attract and influence. Soft power according to Joseph Nye’s notion of persuasion grows out of “intangible power resources”: “such as culture, ideology and institutions”. The EU as a product of cultural dialogues is a civilian power, a normative power and a soft power. The power of persuasion of the EU relies on its legitimacy and credibility in its institutions. For this reason, the consistency between the identity the EU wishes to portray and the practices it should pursue is fundamental to the projection of itself as a credible international actor. This consistency will be necessary if the EU is to fulfill its goal to “enhance unity in diversity”. To do otherwise, would contradict its liberal values and solidify the populist prejudices against the EU. Thus, internal legitimacy and credibility as sources of soft power are ultimately dependent on the consistence between the EU’s identity narrative and democratic values reflected in its practices. Cultural diplomacy responds to the inconsistency by demanding reflection on one hand and enhancing that identity on the other hand. However, in order to export a European cultural image abroad with a single, coherent voice, the Union must first address its ‘unity in diversity’ of national cultures without threatening the national identities of the individual Member States. Therefore, the EU as an international actor and regional organization, based on unity in diversity, has an internal need for intercultural dialogue and negotiation of shared identities . Not only to establish conditions favorable to Brussels policies but as an instrument for the EU to counter external, non-traditional security threats - terrorism, populist narratives, cyber insecurity, energy insecurity and identity ambiguity. This understanding of culture as a potential instrument or means for Europe’s soft power is the basis for this project. In doing so, the main objective of this project is to explore the significance of culture relative to soft power and foreign policy as theoretical foundations for understanding the logic of Erasmus+ Programme.
