Cyber Operations, Accommodative Signaling, and the De-Escalation of International Crises

Abstract

Abstract Signaling is a core element of international crisis bargaining and coercive diplomacy. To succeed in crises, a state must convey to its opponent that it possesses the capability to impose an advantageous outcome and that it is resolved to do so, while also managing the risks of unintended escalation and war. However, less studied in signaling literature is how states can use signals for the purposes of managing escalation risks or even de-escalating crises. In this article, we develop a theory of signaling in cyberspace. We argue that, although cyber operations are not particularly well suited as costly signals of resolve or capabilities in the context of coercive diplomacy, they have a distinct utility for signaling to manage escalation risks. We build a framework organized around the causal mechanisms of accommodative signaling in cyberspace and test it against a set of comparative case studies. We find that cyber operations can act as accommodative signaling under some conditions, particularly when decision makers are faced with managing tensions between simultaneously signaling to domestic audiences and adversary governments.
