To shut our eyes to the part that John Smith plays in the perpetuation of unworkable policies, in building up the forces of which he becomes the vict… - Norman Angell

I would not hesitate to say that nine out of ten of the critics of the peace movement get the argument turned upside down. "You cannot change human nature" has become a sort of incantation with those critics. Perhaps you cannot "change human nature" — I don't indeed know what the phrase means. But you can certainly change human behavior, which is what matters, as the whole panorama of history shows.

We use power, of course, in the international fields in a way which is the exact contrary to the way in which we use it within the state. In the international field, force is the instrument of the rival litigants, each attempting to impose his judgment upon the other. Within the state, force is the instrument of the community, the law, primarily used to prevent either of the litigants imposing by force his view upon the other. The normal purpose of police — to prevent the litigant taking the law into his own hands, being his own judge — is the precise contrary of the normal purpose in the past of armies and navies, which has been to enable the litigant to be his own judge of his own rights when in conflict about them with another.

So long as an individual, whether person or state, has only his own arms to depend upon in order to defend his rights by arms, then he must be stronger than anyone likely to challenge those rights. Which means that that other is deprived of similar defense. Within the frontiers man long ago made the discovery that the only way out of that dilemma is for the community, by putting its combined power behind a protective law, to assume the defense of the individual. Defense must be a communal, a collective function, or it cannot exist effectively at all.
