Abstract

This chapter examines the impact of regional shifts on the making of US foreign policy. One of the most distinctive features of American politics is regionally based political competition and conflict. Scholars argue that regionalism in American politics is rooted in the geographically uneven nature of economic growth and development. The chapter first revisits debates over American foreign policy in the 1890s, the 1930s, and the current era, focusing on issues such as those relating to expansionism and hegemony, internationalism, militarism, and the disagreement between ‘red America’ and ‘blue America’ over foreign policy matters. It then explains how regional diversity causes tension and conflict in foreign policy and argues that conflicts over the purposes of American power, as well as the constitutional authority to exercise it, stem from the distribution of wealth and power in American society among coalitions with divergent interests and claims on the federal government’s resources.
