The nature of political relationships in the United Nations is of considerable interest to students of international organization and, to a lesser degree, to students of international politics. One important aspect of this question concerns the extent to which Western states as a group and the United States in particular dominate the organization. In their examination of this issue many authors contend that the United States prevailed over the United Nations General Assembly during the assembly's earliest years but progressively lost its control as the membership of the organization increased. Their findings, with some variations in detail, indicate that prior to the first significant membership increase in 1955 the United States, with an automatic two-thirds majority in the General Assembly, was dominant. In their view the United States position from 1955 through 1959 was considerably weakened but remained strong enough to ensure favorable decisions by the organization. With further increases in membership during and after 1960, however, they suggest that United States predominance came to an end. Now the newer, less developed, and nonaligned states determine the character and concerns of the UN.
