Cold War, Public Opinion, and Foreign Policy Spending Decisions: Dynamic Representation by Congress and the President

Abstract

Conventional wisdom before the Vietnam War held that public opinion exerted no influence on U.S. foreign policy decisions. Scholars working in Vietnam's aftermath found episodic influence of public opinion on foreign policy, but missing in our understanding were longitudinal examinations of public opinion's influence on foreign policy. A number of post-Vietnam scholars subsequently revealed a long-term relationship between public opinion and defense spending. This study extends that work by analyzing responsiveness to public opinion in different foreign policy arenas by different government institutions, and by accounting for a critical variable not relevant in most previous studies: the end of the cold war. We construct a model explaining the influences of public opinion and the cold war on spending proposals for defense and foreign economic aid by the presidency, the House of Representatives and the Senate. Both public opinion and the end of the cold war exert direct influence on defense spending proposals by the presidency, while the Senate and the House respond primarily to public opinion inputs and the partisan composition of the Senate. In the case of foreign economic aid, the cold war's end gives occasion for increasing spending proposals, contrary to the public's expectation that the end of the cold war minimized the need for the U.S. to provide foreign economic assistance.
