Joint Force Quarterly
Abstract
This article analyzes the strategic importance of Southeast Asia to U.S. foreign policy amid rising competition with China, emphasizing the region's complex geography, diverse political systems, and centrality to global economic growth. It identifies the South China Sea and Strait of Malacca as key flash points where conflict with China could arise and outlines the U.S. military’s need to deter conflict while preparing to win one if necessary. To do so, the United States must build resilient, dispersed basing networks; enhance its ability to maneuver across challenging terrain and maritime environments; and develop robust situational awareness through improved sensors and intelligence-sharing with regional partners. Ultimately, the article argues that without proactive military and diplomatic engagement in Southeast Asia, the United States risks losing critical influence in a region poised to shape the global order.
