Back to Reality: Cross domain deterrence and cyberspace

This paper examines cross domain deterrence strategies involving cyber incidents. By focusing on efforts to halt Russian and Chinese cyber operations against the United States this paper examines the importance of developing, maintaining and implementing (when necessary) cross domain deterrence strategies. This paper departs from more theoretic debates on the value and potential success, or lack thereof relating to cyber deterrence strategies and focuses on two cases in which cross domain retaliations were utilized to halt adversary behavior. From these two cases this paper posits a preliminary theory of cross domain deterrence applicable to cyber interactions between states and advances the debates in the field by shifting the center of gravity away from within domain responses to other mechanisms to deter adversary behavior.
