The Romans never allowed a trouble spot to remain simply to avoid going to war over it, because they knew that wars don't just go away, they are only postponed to someone else's advantage. Therefore, they made war with Philip and Antiochus in Greece, in order not to have to fight them in Italy... They never went by that saying which you constantly hear from the wiseacres of our day, that time heals all things. They trusted rather their own character and prudence- knowing perfectly well that time contains the seeds of all things, good as well as bad.
I consider it a mark of great prudence in a man to abstain from threats or any contemptuous expressions, for neither of these weaken the enemy, but threats make him more cautious, and the other excites his hatred, and a desire to revenge himself.
Though fraud in all other actions be odious, yet in matters of war it is laudable and glorious, and he who overcomes his enemies by stratagem is as much to be praised as he who overcomes them by force.
A multitude is strong while it holds together, but so soon as each of those who compose it begins ro think of his own private danger, it becomes weak and contemptible.
Occasionally words must serve to veil the facts. But let this happen in such a way that no one become aware of it; or, if it should be noticed, excuses must be at hand to be produced immediately.
A prince is also respected when he is a true friend and a true enemy; that is, when he declares himself on the side of one prince against another without any reservation.
