This paper investigates transnational ecologies of the vestiges of war in Southeast Asia, where a shared experience of vulnerability has become the very condition of everyday reality and aesthetic expression. Focusing on the legacies of the U.S. bombardment campaigns in Laos, Cambodia, and Thailand during the Second Indochina War, the author looks at how artists and filmmakers such as Allan Sekula (USA), Tada Hengsapkul (Thailand) Vandy Rattana (Cambodia), and Xaisongkham Induangchanthy (Laos), document the lingering effects—and affects—of Cold War atrocities through topographic aesthetics as a locus of “residual vulnerability”.
