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. HeinleinWe have our hands, we have our brains, we have the challenge all around us, and we have within (from whatever source) the will to strive. That is enough; there is no need to assert 'belief' in that which we do not, as yet, know.
