In world politics and political science, security is one of the most, if not the most discussed topic: “security threats” or ”collective security in the Middle East” are the phrases we hear almost every day. However, the content of this concept is often obscure. When did it take shape and what areas does it cover? What is a security dilemma? What configurations could it have on a global scale and what challenges does it face? The answers to these questions are found in the Valdai Club infographics, prepared for the St. Petersburg International Economic Forum-2019 (SPIEF).
