To ravage, to slaughter, to usurp under false titles, they call empire; and where they make a desert, they call it peace.

[Auferre, trucidare, rapere, falsis nominibus imperium; atque, ubi solitudinem faciunt, pacem appellant.]

Tacitus (c.56-c.120) Roman historian, orator, politician [Publius or Gaius Cornelius Tacitus]
