The book offered to the reader is among the other philosophical and historical works of Igor Efimov, such as Metapolitics, Without Bourgeois, The Shameful Secret of Inequality, The Coming Attila, Twilight of America. Joseph Brodsky, recommending Efimov for the post of teacher at one of the New York universities, wrote that Metapolitics had long been his "desktop reading." In "The Phenomenon of War," the author tries to explore not only the political, economic, ethnic causes of military conflicts, but also the psychological component, the human need to satisfy his thirst for self-affirmation, thirst for cohesion, thirst for immortality. The experience of the novelist (Efimov is the author of fifteen novels) allows him to highlight the most dramatic collisions in the military history of the last three millennia.
