Scipio Africanus Quotes
Prepare for war, since you have been unable to endure a peace.
Livy. The History of Rome, Volume III. Translated by Cyrus R. Edmonds, Henry G. Bohn, 1850.
While this was a common attitude for years before, the horrors of World War II produced a general revulsion to war and an awareness that war between two nations spills over to other states in the region and in an era of globalization, effects countries in other parts of the world. So there has been a tendency to use diplomacy endlessly, even after "things have gone too far".

Publius Cornelius Scipio Africanus (/ˈskɪpioʊ/, /ˈsɪ-/, Latin: [ˈskiːpioː]; 236/235–183 BC) was a Roman general and later consul who is often regarded as one of the best military commanders and strategists of all time. His main achievements were during the Second Punic War. His greatest military achievement was the defeat of Hannibal at the Battle of Zama (near modern Zama, Tunisia) in 202 BC. The victory was one of the feats that earned him the agnomen he is best known for: Africanus.
