Responsibility for the direction and coordination of United States participation in international organizations is vested in the secretary of state. Despite the tremendous growth in United States involvement in international organizations since World War II, the PC reports that the International Organization Bureau of the Department of State has declined from 236 people in 1950 to 155 in 1970. While recognizing that smaller staffs are sometimes more effective than larger ones, the PC is concerned about the capability of the staff to "discharge its responsibilities in planning, supervising, and evaluating the ever-expanding and complex work of the principal organs of the UN as well as the performance of a dozen special bodies or programs of the Organization and 14 UN specialized agencies located around the world."'
