A Comparative Analysis of the United States, China, and Saudi Arabia: Evaluating Cyber Deterrence Strategy at a State Level. University of Aberdeen.https://hdl.handle.net/20.500.14154/76907Master’s dissertation submitted to the University of Aberdeen in partial fulfillment of the requirements for the degree of MSc in Strategic Studies and Management.The study examines the comparative approaches of the United States, China, and Saudi Arabia toward cyber deterrence, focusing on how each state interprets and applies deterrence theory in its strategic context. A qualitative and document-based methodology was used, relying on public and official strategy documents, policy reports, and academic literature. The analysis draws on classical deterrence theory and its modern adaptations, using a framework of punishment, denial, entanglement, and ambiguity as outlined in the literature. Findings show that the U.S. leans more towards deterrence by punishment in the cyber context, reflecting its institutional maturity, but scholars emphasize that heavy dependence on deterrence by punishment in the cyber domain may lead to the risk of escalations. In contrast, China relies on ambiguity and information dominance, rooted in cultural traditions of deception and indirect confrontation, while Saudi Arabia’s deterrence approach is still developing, emphasizing partnerships and denial. The comparative analysis reveals that deterrence in cyberspace is context-dependent, shaped by each state’s political system, culture, and strategic priorities. The results highlight the challenges of attribution, credibility, and signaling in cyberspace, suggesting that credibility depends less on technical capabilities alone and more on perceptions and communication. This study argues for a more nuanced understanding of cyber deterrence, with implications for policymakers and international organizations navigating cyber conflict.61enCyber DeterrenceCybersecurity StrategyStrategic StudiesNational SecurityUnited StatesChinaSaudi ArabiaInternational RelationsThesis
