Structural shape

Each spoke shows one pillar, with 0 at the center and 1 at the edge. The shape reveals whether the pillars are similar or whether one is much lower than the others. That difference is called the .

Additional checks

1 flagged · 9/9 assessed

These checks add context that the overall score can miss. Select a check to see its result, the evidence behind it, and whether enough information was available to assess it.

Data-based checks

These two checks run automatically from the five pillars and public source data.

Case-specific checks

These checks need reviewed historical or political context. A result of “not assessed” means that review has not been completed.

These checks describe structural risk. They do not predict who will act first in a conflict. Differences smaller than 0.03 are treated as too close to rank when countries are compared head-to-head.

Short-term movement is noisy and often reverses. The current level and the durability gap are more informative than a recent change.

capacity to respond after an external shock

HIGH structural exposure but protected by an outside ally: raw adversity is severe, yet a credible external defender both reduces the shock (lowers net exposure) and softens it (lifts response). Persistence despite exposure is the expected reading here (e.g. South Korea).

What happened: Persists as a sovereign state under standing high exposure; no successful invasion since 1953.
