What this comparison cannot tell you
A larger reported inventory or MSS score is not a prediction of military success. Readiness, training, maintenance, geography, logistics, technology quality, alliances, doctrine and objectives sit outside this table.
Country inventory baseline: 2026 edition. Population, GDP, land-area context and military-expenditure trends: World Bank WDI, with the observation year shown at the decision point. Nuclear totals: FAS beginning-of-2026 estimates. Source links and structure reviewed August 25, 2026.
