I am reminded of the history teacher from starship troopers written by Robert Heinlein.

Violence is the golden standard which all other treasures are measured.

Full quote...

"My mother said violence never solves anything." "So?" Mr. Dubois looked at her bleakly. "I'm sure the city fathers of Carthage would be glad to know that."
Lt. Col. Jean V. Dubois (Ret.), p. 25; exchange between him and a student
" … I was not making fun of you personally; I was heaping scorn on an inexcusably silly idea — a practice I shall always follow. Anyone who clings to the historically untrue and thoroughly immoral doctrine that violence never settles anything I would advise to conjure up the ghosts of Napoleon Bonaparte and the Duke of Wellington and let them debate it. The ghost of Hitler could referee and the jury might well be the Dodo, the Great Auk, and the Passenger Pigeon. Violence, naked force, has settled more issues in history than has any other factor, and the contrary opinion is wishful thinking at its worst. Breeds that forget this basic truth have always paid for it with their lives and their freedoms."
He sighed. "Another year, another class — and for me another failure. One can lead a child to knowledge but one cannot make him think."

History teachers are awesome.
