When Goebbels created his “Ministry of Propaganda,” no one could have imagined that he had created a new type of warfare. In the 21st century, wars have taken on a new face. The war has turned not only into a confrontation of military force, but also into a war of information technology. Today, any war begins with an information “shelling”. Why conquer a country by force of arms, encountering resistance and suffering losses? After all, it is possible to subjugate it from within, by the forces of its own citizens. This is the ultimate goal, a global information warfare strategy. American Joseph Overton formulated the theory of the “information window” - a set of measures that allow one to expand the boundaries of what is permissible as far as desired in any society. The method of information warfare is to expand the “Overton window” to such an extent that there is no need to fight, the “prize” itself will fall into your hands. Georgy Pocheptsov is a famous scientist who is a leading theorist of information warfare in the post-Soviet space. His book is devoted to modern methods and technologies of wars in the information space. And after it the world is perceived completely differently.
