Since the second world war, tension has existed in this country between two schools of “internationalists.” One camp has concentrated on the necessity of building and maintaining “positions of strength” in order to deter and tu negotiate with the Soviet Union and Communist China. The second school has stressed the need for “constructive” policies such as foreign aid and liberalized trade in order to foster economic and social progress in the industrialized nations and to promote development in the Third World. Generally speaking, presidents from Truman through Nixon have combined the two approaches, although at various times more attention has been given to one or the other. Most students of American foreign policy would probably agree that power generally has been given priority over development politics since the Korean War.
