In this regard, the article suggests focusing on states’ interpretation of deterrence when designing and implementing their policies in this area, rather than on the problems of applying the concept of deterrence. Such a constructivist approach allows to reveal the peculiarities of the understanding of deterrence without considering them predetermined and identify common aspects of views. Using Russia and the United States as examples, we studied specific features of the application of the deterrence concept in respect to cyberspace in official documents and in the course of the practical implementation of their provisions. The analysis shows that countries interpret the concept of cyberspace deterrence in diff erent ways, with an emphasis on specific deterrence strategies.
