Omissions

• The claim aggregates 27 sovereign states plus EU institutions as a single contributor, which is a different unit of comparison than individual nation-states. The United States alone is the largest single-country financial contributor to the UN system, assessed at 22% of the UN regular budget.
• The EEAS source is an EU institution making a claim about its own financial role, which presents an inherent institutional interest in the framing.
• No specific year or reference period is cited for the claim, though the underlying data is structurally stable across recent years.
