There is nothing as likely to succeed as what the enemy believes you cannot attempt.
Niccolo MachiavelliPrinces and governments are far more dangerous than other elements within society.
Niccolo MachiavelliA prince must be prudent enough to know how to escape the bad reputation of those vices that would lose the state for him, and must protect himself from those that will not lose it for him, if this is possible; but if he cannot, he need not concern himself unduly if he ignores these less serious vices.
Niccolo MachiavelliWhen you disarm your subjects, however, you offend them by showing that either from cowardliness or lack of faith, you distrust them; and either conclusion will induce them to hate you.
Niccolo MachiavelliA prince... must learn from the fox and the lion... One must be a fox in order to recognize traps, and a lion to frighten off wolves. Those who act simply as lions are stupid. So it follows that a prudent ruler cannot, and must not, honour his word when it places him at a disadvantage and when the reasons for which he made his promise no longer exist.
Niccolo MachiavelliIt should be borne in mind that there is nothing more difficult to arrange, more doubtful of success, and more dangerous to carry through than initiating changes. The innovator makes enemies of all those who prospered under the old order, and only lukewarm support is forthcoming from those who would prosper under the new. Their support is lukewarm ... partly because men are generally incredulous, never really trusting new things unless they have tested them by experience.
