At the fourth plenary session of the Conference the treaty relating to the Pacific islands, generally known as the Four-Power Treaty, was presented by Senator Lodge. By the terms of this treaty, the United States, Great Britain, France, and Japan agreed "to respect their rights in relation to their insular possessions and insular dominions in the region of the Pacific Ocean," and in case of any dispute arising out of any Pacific question to refer the matter to a joint conference for consideration and adjustment. This article appeared harmless enough, but Article 2 seemed to lay the foundations of an alliance between these powers. It was as follows: "If the said rights are threatened by the aggressive action of any other Power, the High Contracting Parties shall communicate with one another fully and frankly in order to arrive at an understanding as to the most efficient measures to be taken, jointly or separately, to meet the exigencies of the particular situation." This treaty is to remain in force for ten years, after which it may be terminated by any of the High Contracting Parties on twelve months' notice. It supersedes the Anglo-Japanese Alliance which, it expressly provided, should terminate on the exchange of ratifications. In presenting the treaty, Senator Lodge assured his hearers that "no military or naval sanction lurks anywhere in the background or under cover of these plain and direct clauses," and Secretary Hughes in closing the discussion declared that it would probably not be possible to find in all history "an international document couched in more simple or even briefer terms," but he added, "we are again reminded that the great things are the simple ones." In view of these statements the members of the Conference and the public generally were completely flabbergasted some days later when Secretary Hughes and the President gave out contradictory statements as to whether the treaty included the Japanese homeland. Hughes stated to the correspondents that it did, the President said it did not. Whereupon some wag remarked that at Paris President Wilson did not let the American delegation know what he did, while at Washington the delegates did not let President Harding know what they were doing. In deference to the President's views and to criticisms of the treaty in the Japanese press a supplementary treaty was later signed expressly declaring that the term "insular possessions and insular dominions" did not include the Japanese homeland.
