It is with deep sorrow that we have learnt of the passing of President of the Atlantic Council of Croatia and Croatian Association for International Studies, Prof. Radovan Vukadinovic PhD earlier this week. He will be remembered as an extraordinary expert in international relations, political scientist and an expert for foreign policy. Even after he retired as a professor at the Faculty of Political Science in Zagreb, he lectured at private universities and was a mentor to many doctoral candidates. Through his work in the non-governmental sector, Prof. Vukadinovic dealt with international relations, with a specific accent on international security, and in many aspects thanks to Professor’s work the Republic of Croatia became a member of the Euro-Atlantic family, mainly the NATO Alliance. His work also greatly influenced the evolution of the Western Balkan countries in accepting Euro-Atlantic values.
