“Men are expendable; women and children are not. A tribe or a nation can lose a high percentage of its men and still pick up the pieces and go on… as long as the women and children are saved. But if you fail to save the women and children, you’ve had it, you’re done, you’re through! You join Tyrannosaurus Rex, one more breed that bilged its final test.” – Robert A. Heinlein, “The Pragmatics of Patriotism” address at the U.S. Naval Academy, April 5, 1973, later published in the book “Expanded Universe” (1980)
