Peace is normally a great good, and normally it coincides with righteousness, but it is righteousness and not peace which should bind the conscience of a nation as it should bind the conscience of an individual; and neither a nation nor an individual can surrender conscience to another's keeping.
The best soldier does not attack. The superior fighter succeeds without violence. The greatest conqueror wins without struggle. The most successful manager leads without dictating. This is intelligent non aggressiveness.
