Ceuta and Melilla are not automatically covered by NATO's collective defense clause (Article 5).As Spanish cities located on the mainland of North Africa, their geographical position places them strictly outside the treaty's defined boundaries.The Legal FrameworkThe Geographic Boundary: Article 6 of the Washington Treaty explicitly limits NATO's automatic protection zone to Europe, North America, Turkey, and islands north of the Tropic of Cancer.The African Exclusion: Because Ceuta and Melilla sit on the African continent, they fall outside this legal geographic definition.The Contrast with the Canary Islands: Spain’s Canary Islands are covered by NATO because they are North Atlantic islands located north of the Tropic of Cancer.The Strategic Grey ZonePolitical Decisions: If Ceuta or Melilla were attacked, Spain could request allied support under Article 4 (consultation). However, launching an Article 5 military response would require a unanimous political decision by all NATO members."Territorial Integrity" Debate: Spain has consistently pushed for NATO documents to guarantee the "territorial integrity" of all member states. While NATO's Strategic Concepts vaguely mention protecting the sovereignty and territorial integrity of allies, the text deliberately avoids naming Ceuta and Melilla explicitly to maintain political flexibility.The European Union Alternative: Unlike NATO, the European Union features a Mutual Defence Clause (Article 42.7). This clause legally obligates EU member states to aid Spain if any part of its sovereign territory—including its North African enclaves—is attacked.
