There are a dozen different ways of delivering destruction in impersonal wholesale, via ships or missiles of one sort or another, catastrophes so widespread, so unselective that the war is over because that nation or planet has ceased to exist. What we do is entirely different. We make war as personal as a punch in the nose. We can be selective, applying precisely the required amount of pressure at the specified point at a designated time. We've never been told to go down and kill or capture all left-handed redheads in a particular area, but if they tell us to, we can. We will.
Robert A. HeinleinNothing of value is free. Even the breath of life is purchased at birth only through gasping effort and pain... The best things in life are beyond money; their price is agony and sweat and devotion... and the price demanded for the most precious of all things in life is life itself--ultimate cost for perfect value
