Attempts to explain world politics in terms of the clashes of sharply defined national interests have an air of unreality. This is because of the unequal interest of groups of the population in any particular course of official action. The little known and obscure, but historically important episode with which this article deals, describes the impact of one influential private group on foreign policy, even after the President of the United States had made an official determination of policy. It also throws light on the way in which a private group can operate through and with a foreign government, whose interests are parallel to its own, to change the direction of American policy. Similarly it illustrates how a foreign government can mould its relations with the United States (or with most countries) by developing a policy with a special appeal to particularly influential groups in that country.
