A king who has wisdom and the eye of political science can, even with small effort, formulate sound strategy; and he can outmaneuver opponents who possess initiative and effective power by means such as conciliation and the other expedients, and by secret methods.
That trained political understanding multiplies effectiveness—reducing required effort and enabling indirect methods to defeat materially stronger adversaries.
As confidential/secret techniques of statecraft—covert operations, deception, psychological tactics, and hidden arrangements used alongside open diplomacy.
