"The world will never have lasting peace so long as men reserve for war the finest human qualities. Peace, no less than war, requires idealism and self-sacrifice and a righteous and dynamic faith"

This quote by John Foster Dulles speaks to the idea that peace is not something that can be accomplished without effort. He suggests that peace needs the exact same level of idealism, self-sacrifice, faith, and dynamism as war does. He suggests that if we book the very best of our human qualities for war, then we will never ever have long lasting peace. This quote speaks with the idea that peace is something that should be actively pursued and worked for, which it is not something that will happen naturally. It is a reminder that peace is something that needs to be defended, simply as war is.
