Replication Data for: Public Opinion and Alliance Commitments in Cybersecurity: An Attack Against All?

Cyber operations as a facet of international competition pose a direct challenge to alliances. Designed to respond to conventional military attacks, alliances like the North Atlantic Treaty Organization must now determine how their defensive commitments translate into the digital domain. This question is not limited to political and military elites, as the use of force in defense of allies is among the most politically charged decisions a state can make and relies significantly on public support. This article extends recent public opinion literature on cyber conflict to investigate public attitudes toward existing treaty commitments following a destructive cyber operation against an allied state. Using a survey experiment involving U.S. nationals, we find that while participants are sensitive to treaty obligations, these effects are moderated by individual factors like domain expertise. Furthermore, we observe that specific aggressor-ally dyads tied to geographic regions can shape public preferences, with participants being more reactive to Europe-based scenarios than comparable treatments in Asia.
