War must be, while we defend our lives against a destroyer who would devour all; but I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend.1Perhaps that is all one can say. There are times when war must be, such as when a political or religious power threatens to destroy and devour all. Yet, we do not glorify war or the weapons of war; we rejoice in those things against which war can and has defended. We glory in people who have freedom to choose their politics, their religions, and their philosophies. We reluctantly go to war so that we might love peace.
