It depends on the official determination on who is the aggressor. In any but the most blatant attacks, this determination will be a political process.
Yes, NATO's article 5 states:
Article 5
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, to restore and maintain the security of the North Atlantic area.
So, as a NATO member, if Greece was attacked then all of NATO's members would have to defend them.
