My opposition to war is not based upon pacifist or non-resistant principles. It may be that the present state of civilization is such that certain international questions cannot be discussed; it may be that they have to be fought out. But the fighting never settles the question. It only gets the participants around to a frame of mind where they will agree to discuss what they were fighting about.
