  • For this research, “ally” refers to countries that are either NATO members or designated as Major Non‑NATO Allies (MNNA) by the United States. MNNA status is an official U.S. designation granting certain military and financial cooperation benefits, even though the country is not part of NATO. In addition, NATO maintains formal partnerships with other countries through programs such as the Partnership for Peace (PfP), Mediterranean Dialogue, Istanbul Cooperation Initiative, and global partners. These partnerships involve political dialogue, security cooperation, and interoperability.
  • Alliances tend to remain stable, but can change quickly in certain circumstances. For example, had the United States invaded Greenland in 2025, as some feared might happen, many NATO members would likely have renounced their alliance with the United States, as Greenland is in fact part of Denmark, another member of NATO.
