What remains unresolved.
Global coverage remains partial
Coverage follows specific researched facilities, financial records and institutional relationships; countries connected only by NATO membership are excluded. This is not a complete list of US treaty allies, security partners, overseas bases, export licences, investments or cash flows.
Next research step: Add further regional records using local public accounts, procurement notices, aid disbursement data, sovereign-fund reports and community-reviewed translations. Record the search period and missing jurisdictions.
The NATO budget slice is historical
The 2024 values are estimates from a report with a 3 June 2025 cutoff. They provide a consistent historical comparison, not the latest national budget. Iceland is absent from this table; absence is not zero.
Next research step: Version the table against later NATO releases and national audited accounts, preserving the original estimate and recording changed definitions and currencies.
