[Someone]

Somebody should help terrorists choose names for their organizations, then:

  - PLO = Palestine Liberation Front

  - ETA = Basque Homeland and Freedom

  - IRA = Irish Republican Army

etc. I would call someone whose goal is killing a soldier or a murderer. IMO, the reason terrorists kill civilians is the same as why, in a dispute between two children of largely different strength, the one who is verbally weakest will start fighting, and the one who is physically weakest then will start fighting dirty (biting, nail scratching, hair pulling, etc)
