"Often war is waged only in order to show valor; thus an inner dignity is ascribed to war itself, and even some philosophers have praised it as an ennoblement of humanity, forgetting the pronouncement of the Greek who said, 'War is an evil in as much as it produces more wicked men than it takes away.'"

There never was a good war," said Franklin. "There have indeed been many wars in which a good man must take part, and take part with grave gladness to die if need be, a willing sacrifice, thankful to give life for what is dearer than life, and happy that even by death in war he is serving the cause of peace. But if a war be undertaken for the most righteous end, before the resources of peace have been tried and proved vain to secure it, that war has no defense, it is a national crime.
