When did Spain join NATO:

🧠 Explanation:

Spain became a member of NATO (North Atlantic Treaty Organization) in 1982. NATO is a political and military alliance established for mutual defense and security among member countries. The word “joined” is a verb in the past tense, indicating the action of becoming a member, while “Spain” and “NATO” are proper nouns. Alternative phrases could include “entered NATO” or “became part of NATO,” but “joined” is the standard term used in historical and political contexts. For PPSC exams, remembering 1982 as the year Spain joined NATO is important for questions related to international alliances and European political history.
