Si vis pacem, para bellum

Si vis pacem, para bellum is a Latin adage translated as, "If you want peace, prepare for war". The adage was adapted from a statement found in Book 3 of Latin author Publius Flavius Vegetius Renatus's tract De Re Militari (4th or 5th century), although the idea it conveys is also present in earlier works, such as Plato's Nomoi (Laws).
