War is merely a continuation of politics.

Although our intellect always longs for clarity and certainty, our nature often finds uncertainty fascinating.

In war, while everything is simple, even the simplest thing is difficult. Difficulties accumulate and produce frictions which no one can comprehend who has not seen war.

War is not an independent phenomenon, but the continuation of politics by different means.

War is an act of force, and to the application of that force there is no limit. Each of the adversaries forces the hand of the other, and a reciprocal action results which in theory can have no limit.

War should never be thought of as something autonomous, but always as an instrument of policy.

The more a leader is in the habit of demanding from his men, the surer he will be that his demands will be answered.
