War is simply the continuation of politics by other means - Carl von Clausewitz

Modern wars are seldom fought without hatred between nations; this serves more or less as a substitute for hatred between individuals.

Our discussion has shown that while in war many different roads can lead to the goal, to the attainment of the political object, fighting is the only possible means.

An immense space lies between a General — that is, one at the head of a whole War, or of a theatre of War — and his Second in Command, for the simple reason that the latter is in more immediate subordination to a superior authority and supervision, consequently is restricted to a more limited sphere of independent thought.
