If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected.
The good fighters of old first put themselves beyond the possibility of defeat, and then waited for an opportunity of defeating the enemy. To secure ourselves against defeat lies in our own hands, but the opportunity of defeating the enemy is provided by the enemy himself. Thus the good fighter is able to secure himself against defeat, but cannot make certain of defeating the enemy.
The great body of our citizens shoot less as times goes on. We should encourage rifle practice among schoolboys, and indeed among all classes, as well as in the military services by every means in our power. Thus, and not otherwise, may we be able to assist in preserving peace in the world... The first step – in the direction of preparation to avert war if possible, and to be fit for war if it should come – is to teach men to shoot!
I will not wage war against women and children! I have instructed my air force to limit their attacks to military objectives. However, if the enemy should conclude from this that he might get away with waging war in a different manner he will receive an answer that he'll be knocked out of his wits!
