The Publication of the diplomatic papers of Other Governments
An expert on foreign affairs has summarized the limitation upon the right of a government to make public the diplomatic papers which it has received from another government as follows: “ … one party to a negotiation cannot, in honor and in courtesy, publish the negotiation without the consent of the other party, on pain of forfeiting that good-will upon which … ‘the peace of the world ultimately depends.’ ” This principle of consent to publication is accepted, with some reservations and exceptions, by American practice. But American practice in this matter is not generally accepted by all foreign offices and it is not precisely and definitely written into international law. It has been generally observed in normal times by the Great Powers, which have had most to gain by its application, and it has frequently been disregarded by small powers and by Great Powers in times of stress. It rests upon comity and reciprocity, not upon international legislation.
