In the book of a prominent Serbian scientist, director of the Institute of Contemporary History of Serbia, Doctor of Historical Sciences Mile Belajac, “Who needs a revision of history? Old and new debates about the causes of the First World War”, published for the first time in Russian, scrupulously examines all attempts to revise the history of the Great War, its nature, causes and “underside” and rebuffs those who are in a hurry to write down Russia and the executor of its “imperial will” Serbia as the instigators of that bloody massacre and project this “discovery” onto the situations of the thirties, forties and nineties of the twentieth century. The monograph of an authoritative scientist is the result of an in-depth analysis of a solid corpus of books, articles and other publications that were published in Europe and the USA during the period from the end The First World War to the present day.
