The other type of duty is the international duty, the duty owed by one nation to another. I hold that the laws of morality which should govern individuals in their dealings one with the other, are just as binding concerning nations in their dealings one with the other. The application of the moral law must be different in the two cases, because in one case it has, and in the other it has not, the sanction of a civil law with force behind it. The individual can depend for his rights upon the courts, which themselves derive their force from the police power of the State. The nation can depend upon nothing of the kind; and therefore, as things are now, it is the highest duty of the most advanced and freest peoples to keep themselves in such a state of readiness as to forbid to any barbarism or despotism the hope of arresting the progress of the world by striking down the nations that lead in that progress. It would be foolish indeed to pay heed to the unwise persons who desire disarmament to be begun by the very peoples who, of all others, should not be left helpless before any possible foe. But we must reprobate quite as strongly both the leaders and the peoples who practise, or encourage, or condone, aggression and iniquity by the strong at the expense of the weak. We should tolerate lawlessness and wickedness neither by the weak nor by the strong; and both weak and strong we should in return treat with scrupulous fairness. The foreign policy of a great and self-respecting country should be conducted on exactly the same plane of honour, of insistence upon one’s own rights and of respect for the rights of others, that marks the conduct of a brave and honourable man when dealing with his fellows. Permit me to support this statement out of my own experience. For nearly eight years I was the head of a great nation, and charged especially with the conduct of its foreign policy; and during those years I took no action with reference to any other people on the face of the earth that I would not have felt justified in taking as an individual in dealing with other individuals.
