“Peace?' said Vetinari. 'Ah, yes, defined as period of time to allow for preparation for the next war.”
“Where resides the comforting knowledge of history's vast, cyclical sweep, the ebb and flow of wars and peace? Peace is the time of waiting for war. A time of preparation, or a time of willful ignorance, blind, blinkered and prattling behind secure walls.”
“if you want peace, prepare for war”
“Let him who desires peace prepare for war. ”
“In peace, as a wise man, he should make suitable preparation for war.”
“Prepare for war, since you have been unable to endure a peace.”
