The onrush of enormous changes that struck American foreign relations in 1940-1941 brought with it most of the current problems in the administration of foreign affairs. For one change, the conduct of foreign relations has become not only the largest function of the federal government, but also the largest function of all governments in the United States. In 1948, at midpoint between World War II and war in Korea, the costs of foreign relations, including military outlays, accounted for 54 per cent of all money spent by all governments, federal, state, and local, for all public purposes. No matter whether we measure the relative size in costs, in personnel devoted to it, in impact upon the political economy, or in commitments of the United States, this work of government has exceeded all other.
