“Far from making peace, wars invariably serve as classrooms and laboratories where men and techniques and states of mind are prepared for the next war.”

“Happy the state which in times of peace is yet prepared for war.”
Felix est illa civitas quae in pace bellum cogitat.

“Peace?' said Vetinari. 'Ah, yes, defined as period of time to allow for preparation for the next war.”

“Most Americans mistakenly believe that peace is the normal condition of mankind, while war is some weird aberration. Actually, it’s the other way around. Most of human history has to do with war, and preparations for the next one. But we Americans do not prepare for the next war, are invariably surprised when it erupts, and, since we did not take prudent steps when it would have been relatively simple to prevail, usually end up fighting on our enemies’ more difficult and costly terms.”

“Peace, if it ever exists, will not be based on the fear of war, but on the love of peace. It will not be the abstaining from an act, but the coming of a state of mind.”

“In peace, as a wise man, he should make suitable preparation for war.”
in pace, ut sapiens, aptarit idonea bello

“Peace is not the absence of war, it is a virtue, a state of mind, a disposition of benevolence, confidence, justice.”

“We must be prepared to make the same heroic sacrifices for the cause of peace that we make ungrudgingly for the cause of war.”

“The only way to have peace is to prepare for war.”

“It turns out that the Romans were champs in making peace. Their motto was that if you want to make peace, you need to prepare for war. They knew game theory.”
