Violence never settles anything should be debated by the ghosts of Hitler and Stalin, with the city fathers of Carthage as referees.
Robert A. HeinleinFrom the strictest humanitarian viewpoint, any attempt to stop the processes by which over crowded cities purge themselves is not a kindness.
Robert A. HeinleinWar is not violence and killing, pure and simple; war is controlled violence, for a purpose. The purpose of war is to support your government's decisions by force. The purpose is never to kill the enemy just to be killing him but to make him do what you want him to do. Not killing... but controlled and purposeful violence.
Robert A. Heinlein
