Diplomacy is facing unprecedented challenges. How can Germany, how can the European Union, confidently and sovereignly navigate a world in which everything is changing? Volker Perthes has written a book on this topic ("The Multipolarization of the World – A Geopolitical Guide") and discussed it with diplomats and journalists. For the program "diplo.international," host Ewald König, publisher of diplo.news, invited Volker Perthes for a discussion.
