Establishing lasting peace is the work of education all politics can do is keep us out of war.

Experience has shown how deeply the seeds of war are planted by economic rivalry and social injustice.

War settles nothing.

Empathy is really the opposite of spiritual meanness. It's the capacity to understand that every war is both won and lost. And that someone else's pain is as meaningful as your own.

A man who says that no patriot should attack the war until it is over... is saying no good son should warn his mother of a cliff until she has fallen.

War is so unjust and ugly that all who wage it must try to stifle the voice of conscience within themselves.

A professional soldier understands that war means killing people, war means maiming people, war means families left without fathers and mothers.

The only excuse for war is that we may live in peace unharmed.

A time will come when a politician who has willfully made war and promoted international dissension will be as sure of the dock and much surer of the noose than a private homicide. It is not reasonable that those who gamble with men's lives should not stake their own.

The only defensible war is a war of defense.
