This podcast is performed by Alessandro Marrone. The aim of the briefing is to analyze the debate within NAYO on which role the Alliance may play with regard to the arch of crisis stretching from the Mediterranean Sea to the Black Sea across the Middle East and Ukraine. Particular attention will be paid to the different threat perceptions of NATO Member States with respect to the Eastern and Southern flanks of the Alliance, the strategies agreed so far to deal such security threats and challenges, and the future perspectives.
