Presidents Harding and Coolidge handled foreign relations in much the same way they managed domestic affairs. Harding deferred to senatorial prejudice against executive domination in the area and let Secretary of State Charles Evans Hughes make policy. Coolidge adopted a similar course. In directing foreign relations, they faced the obstacle of a resurgent isolationism. The bloodiness and apparent senselessness of the Great War convinced millions that the only way to be sure it would not happen again was to “steer clear” of “entanglements.” That these famous words had been used by Washington and Jefferson in vastly different contexts did not deter the isolationists of the 1920s from attributing to them the same authority they gave to Scripture. On the other hand, far-flung American economic interests, as well as the need for both raw materials for industry and foreign markets for America’s growing surpluses of agricultural and manufactured goods, made close attention to and involvement in developments all over the world unavoidable.
Isolationist sentiments, therefore, did not deter the government from seeking to advance American interests abroad. The Open Door concept remained predominant; the State Department worked to obtain opportunities in underdeveloped countries for exporters and investors, hoping both to stimulate the American economy and to bring stability to “backward” nations. Although this policy sometimes roused local resentments because of the tendency of the United States to support entrenched elites while the mass of peasants and city workers lived in poverty, it also resulted in a further retreat from active interventionism.
The first important diplomatic event of the period revealed a great deal about American foreign policy after the Great War. During the war, Japan had greatly increased its influence in East Asia, especially in Manchuria, the northeastern province of warlord-dominated China. To maintain the Open Door in China, it would be necessary to check Japanese expansion. But there was little hope of restoring the old spheres of influence, which the mass of Chinese people bitterly resented. In addition, Japan, the United States, and Great Britain were engaged in expensive naval building programs, a competition none of them really wanted but from which all dared not withdraw unilaterally.
In November 1921, hoping to reach a general agreement with China, Japan, and the Europeans that would keep China open to the commerce of all and slow the armaments race, Secretary of State Hughes convened a conference in Washington. By the following February the Washington Conference had drafted three major treaties and a number of lesser agreements.
In the Five-Power Treaty, the United States, Great Britain, France, Japan, and Italy agreed to stop building battleships for ten years and to reduce their fleets of battleships ships to a fixed ratio, with Great Britain and the United States limited to 525,000 tons, Japan to 315,000 tons, and France and Italy to
175,000 tons. The new ratio was expected to produce a balance of forces in the Pacific.
The Four-Power Treaty, signed by the United States, Great Britain, Japan, and France, committed these nations to respect one another’s interests in the islands of the Pacific and to confer in the event that any other country launched an attack in the area.
All the conferees signed the Nine-Power Treaty, agreeing to respect China’s independence and to maintain the Open Door. On the surface, this was of monumental importance to the United States since it seemed to mean that Japan had given up its territorial ambitions on the Asian mainland and that both the Japanese and the Europeans had formally endorsed the Open Door concept.
By taking the lead in drafting these agreements, the United States regained some of the moral influence it had lost by not joining the League of Nations. The treaties, however, were uniformly toothless. The signers of the Four-Power Treaty agreed only to consult in case of aggression in the Pacific; they made no promises to help one another or to restrict their own freedom of action. As President Harding assured the Senate, “there [was] no commitment to armed force, no alliance, no written or moral obligation to join in defense.”
The naval disarmament treaty said nothing about the number of other warships that the powers might build, about the far more important question of land and air forces, or about the underlying industrial and financial structures that controlled the ability of the nations to make war. In addition, the 5:5:3 ratio actually enabled the Japanese to dominate the western Pacific. It made the Philippine Islands indefensible and exposed Hawaii to possible attack. In a sense these American bases became hostages of Japan. Yet Congress was so unconcerned about Japanese sensibilities that it refused to grant any immigration quota to Japan under the National Origins Act of 1924, even though the formula applied to other nations would have allowed only 100 Japanese a year to enter the country. The law, Secretary Hughes warned, produced in Japan “a sense of injury and antagonism instead of friendship and cooperation.”
Hughes did not think war a likely result, but Japanese resentment of “white imperialism” played into the hands of the military party in that nation. Many Japanese army and navy officers considered war with the United States inevitable.
As for the key Nine-Power Treaty, Japan did not abandon its territorial ambitions in China, and China remained so riven by conflict among the warlords and so resentful of the “imperialists” that the economic advantages of the Open Door turned out to be small indeed.
The United States entered into all these agreements without realizing their full implications and not really prepared to play an active part in East Asian affairs. “We have no favorites in the present dog fight in China,” the head of the Far Eastern division of the State Department wrote of the civil war going on there in 1924. “They all look alike to us.” The Japanese soon realized that the United States would not do much to defend its interests in China.
