Fast forward to today and the North Atlantic Treaty Organization's first operation involving combat inside or outside of Europe. No one has rewritten Article 5 of NATO's Charter since April 4, 1949. It still reads, in part: "The parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack against them all and consequently they agree that, if such an armed attack occurs, each of them, in exercise of the right of individual or collective self-defence recognized by Article 51 of the Charter of the United Nations, will assist the Party or Parties so attacked by taking forthwith, individually and in concert with the other Parties, such action as it deems necessary, including the use of armed force ..."
But Serbia did not attack any NATO member, so why did Greece or any other nation in NATO have to go along and provide support?
Seems like the charter was warped into meaning any NATO country must get on board and provide support to NATO-led wars if demanded by key NATO countries (even if the country never attacked a NATO country).
