The third training seminar organized by the Center for International Strategic Analyses-KEDISA on 13-14 December 2017 on the subject of “Geopolitical Competitions and Power Games of Naval and Continental Powers” was completed with great success. The lecturer was Dr. Ilias Iliopoulos, Professor of the American College of Greece (PhD in International Relations and Diplomatic History at the University of Munich). The seminar was organized with the kind support of the Aegean College at its hospitable facilities at 17, Panepistimiou Street in Athens. KEDISA, following the difficult economic climate, organized the training seminar once again with extremely friendly prices for employees and students. The participants were able to attend a very interesting seminar that analyzed in depth Geopolitical Competitions and Power Games of Naval and Continental Powers, emphasizing on contemporary history. At the end of the seminar, attendees were granted certificates of attendance and educational material on CDs. KEDISA is continuously pursuing its developmental pathway with a view to promoting scientific knowledge and providing opportunities for students and young scientists in the field of Strategy and International Relations.
