Comparative Analysis of Cyber Diplomacy in Small States and Powers

Thesis Abstract

In an era of pervasive digital connectivity, cyber diplomacy has emerged as a critical frontier for statecraft, with small states facing distinctive constraints and opportunities compared to larger powers. The study investigates how small states leverage cyber diplomacy to safeguard sovereignty, promote normative standards, and influence regional and global cyber governance, while comparing these dynamics with those of major powers. The aim is to uncover systematic differences and commonalities in approaches, instruments, and outcomes, and to illuminate how capacity, vulnerability, and strategic interests shape diplomatic trajectories in cyberspace. Specific objectives are to (i) map the repertoire of cyber diplomacy practices employed by selected small states and powers, (ii) assess the influence of domestic cyber capacity and international alignments on diplomatic outcomes, (iii) evaluate the effectiveness of cyber norms advocacy and its translation into policy instruments, (iv) test theoretical propositions from Constructivist and Realist perspectives on norm diffusion and power projection, and (v) develop a comparative framework that links cyber diplomacy to broader foreign policy goals. The study adopts a mixed-methods design, combining qualitative comparative analysis with quantitative testing. The population comprises national cyber diplomacy portfolios, official statements, and bilateral/casto multilateral engagements of ten small states (including Estonia, Singapore, and Lithuania) and ten major powers (including the United States, China, and the European Union as a collective actor). A purposive sample of 60 in-depth elite interviews with diplomats, cyber policy officials, and international organization delegates will be conducted, complemented by 120 published official documents, policy papers, and treaty texts from 2015–2025. Data collection instruments include semi-structured interview guides, a coding scheme for categorical content analysis of official communiqués, and a standardized instrument for assessing diplomatic outcomes such as treaty participation, norms adoption, and alliance-building indicators. The validity of instruments will be ensured through triangulation of interview data with document analysis and expert validation panels; reliability will be enhanced by intercoder agreement checks (Cohen’s kappa > 0.80) and pilot testing. Analytical techniques encompass thematic analysis for interview transcripts grounded in a dual-theory lens of Constructivism (norms, legitimacy, and identity in cyber governance) and Offensive Realism (power projection and strategic leverage in cyberspace). Quantitative analysis will include regression models to examine the relationship between domestic cyber capacity indicators (budget, personnel, and incident response capabilities) and diplomatic outcomes, as well as a multi-variable ANOVA to compare differences between small states and powers across categories of cyber diplomacy, such as normative advocacy, capacity-building assistance, and incident diplomacy. A qualitative comparative analysis (QCA) will identify configurations of factors associated with successful cyber diplomacy outcomes in both cohorts. The study will also employ a stylized conceptual model mapping inputs (capacity, norms climate, alliance networks) to processes (dialogue, norm diffusion, crisis response) and outputs (policy alignment, treaty commitments, and public legitimacy). Key expected findings include (i) small states tend to leverage normative leadership, transparent governance, and incident transparency to gain legitimacy and influence, albeit constrained by limited coercive leverage; (ii) major powers rely more on strategic signaling, cyber capability demonstrations, and bilateral/multilateral leverage to shape norms and governance architectures; (iii) domestic cyber capacity and alliance alignment mediate success in cyber diplomacy more significantly in small states than in powers, while powers profit from broader institutional leverage; (iv) norm diffusion is most rapid when complemented by concrete capacity-building and technical cooperation packages. The study contributes to knowledge by offering a rigorous, theory-informed comparative framework that elucidates how cyber diplomacy operates differently across state sizes, integrates normative and strategic explanations for international cyber governance outcomes, and provides policy-oriented insights on how small states can optimize diplomatic leverage. The main conclusion anticipates that balancing normative leadership with targeted capacity development and alliance-based leverage yields the most durable diplomatic gains for small states, while powers augment legitimacy and governance influence through consistent norm promotion, credible commitments, and transparent incident management. Recommended avenues include expanding multistakeholder engagement, strengthening regional cyber policy coalitions, and institutionalizing ongoing evaluative metrics for cyber diplomacy effectiveness.
