Figure 2. Nuclear Powers and the Six Load-Bearing Functions (Comparative Systems Assessment)

This dataset supports Figure 2, Nuclear Powers and the Six Load-Bearing Functions (Comparative Systems Assessment), developed under the Nuclear Systems Externality Doctrine (2026). The figure provides a comparative systems-assessment matrix of publicly recognized nuclear-armed states and evaluates how each state aligns with six load-bearing functions: monetary and reserve-system anchoring, food and agricultural stabilization, energy and industrial continuity, defense-industrial sustainment, alliance and security-guarantee credibility, and technology/data infrastructure centrality. The purpose of the figure is to clarify that nuclear-armed states may differ not only by arsenal size, military doctrine, or regional influence, but also by their embeddedness within global systems. A “load-bearing nuclear state” is defined as a nuclear-armed state whose collapse or catastrophic disruption would impair multiple systems beyond its own territory. The figure distinguishes between full-spectrum load-bearing states, partial or sectoral load-bearing states, and nuclear states whose systemic role remains primarily regional or limited. The comparative framework is not a ranking of national legitimacy, moral worth, sovereignty, or strategic desirability. It does not assign blame, hostile intent, or vulnerability targeting. Rather, it functions as a public-source systems model for evaluating how nuclear powers interact with global finance, food supply chains, energy markets, defense-industrial systems, alliance structures, and digital infrastructure. The dataset is intended for researchers in strategic studies, international security, systems analysis, political economy, defense policy, nuclear deterrence, critical infrastructure, and global risk assessment. It may support further work on systemic interdependence, deterrence stability, externality propagation, resilience planning, and comparative state-function analysis. Figure 2 should be read alongside Figure 1, which defines the six load-bearing functions structurally. Figure 2 extends that model by applying the six-function framework across nuclear-armed states to identify differences in systemic centrality, substitution difficulty, and cross-domain dependency concentration. Its analytical value lies in showing that all nuclear powers are strategically consequential, but not all nuclear powers perform the same global systems role. This dataset relies on public, non-classified, non-operational indicators and is designed for scholarly evaluation, policy analysis, and systems-level comparison. It does not provide technical guidance, operational pathways, or adversarial targeting information.
