IV. Every nation has the right to territory within defined boundaries, and to exercise exclusive jurisdiction over its territory, and all persons whether native or foreign found therein. V. Every nation entitled to a right by the law of nations is entitled to have that right respected and protected by all other nations, for right and duty are correlative, and the right of one is the duty of all to observe. VI. International law is at one and the same time both national and international; national in the sense that it is the law of the land and applicable as such to the decision of all questions involving its principles; international in the sense that it is the law of the society of nations and applicable as such to all questions between and among the members of the society of nations involving its principles.[282] This Declaration has been criticized as being too altruistic for a world in which diplomacy has been occupied with selfish aims. On the same day that the above Declaration was made public, President Wilson delivered a notable address before the Second Pan American Scientific Conference then in session at Washington. In the course of this address he said: The Monroe Doctrine was proclaimed by the United States on her own authority. It has always been maintained, and always will be maintained, upon her own responsibility. But the Monroe Doctrine demanded merely that European governments should not attempt to extend their political systems to this side of the Atlantic. It did not disclose the use which the United States intended to make of her power on this side of the Atlantic. It was a hand held up in warning, but there was no promise in it of what America was going to do with the implied and partial protectorate which she apparently was trying to set up on this side of the water, and I believe you will sustain me in the statement that it has been fears and suspicions on this score which have hitherto prevented the greater intimacy and confidence and trust between the Americas. The states of America have not been certain what the United States would do with her power. That doubt must be removed. And latterly there has been a very frank interchange of views between the authorities in Washington and those who represent the other states of this hemisphere, an interchange of views charming and hopeful, because based upon an increasingly sure appreciation of the spirit in which they were undertaken. These gentlemen have seen that, if America is to come into her own, into her legitimate own, in a world of peace and order, she must establish the foundations of amity, so that no one will hereafter doubt them. I hope and I believe that this can be accomplished.
