The book review is dedicated to a work that tackles one of the trendiest concepts of recent times. The book concentrates on the conceptualization of the notion of hybrid war and its perception on both sides of the Atlantic. The declared goal of the book was to investigate how political forces have shaped conceptual thinking between the West and Russia and explain the reasons for mutual criminations. Combining quantitative and qualitative methods the author examined large amounts of literature and took an exploratory approach to dig into categorical data from both American and Russian thinkers’ works then compared the conceptual usage of them.
