The U.S. government, media, and public were aware of “comfort girls” as early as 1942. Yet, after the conclusion of the Asia Pacific War, their collective knowledge faded away from the public sphere. How did this happen? This paper examines this question from both micro and macro-perspectives. At a micro-level, individual Americans, in particular missionaries, initially discussed the need to assist comfort girls after the war and initiated programs, such as shelters, for them in Korea. However, the chaos caused by the division of the peninsula, the U.S. military’s haphazard decolonization policies, and the outbreak of the Korean War led the missionaries to shift their focus from assisting comfort girls to rehabilitating “delinquent women.” At a macro level, the U.S. military and government viewed the post-World War II period through a simplistic binary lens, democracy versus communism, that left the continuing tensions between former colonial masters and colonies from the center of focus. (South) Korea’s postcolonial past ill-fit this binary to the extent that it brought to the foreground Japan’s colonial responsibilities in postwar deliberations. In fact, colonial atrocities, like “comfort girls” needed to be silenced so that postwar peace might be constructed between the U.S. and Japan.
