ABSTRACT One way that the United States conducted the Cold War was through its surplus food programmes (Public Law 480), which fed the hungry and supported anticommunist regimes. Consequently, South Koreans consumed over fourteen times more wheat flour by 1960 than during the preceding Japanese colonial period. This study presents a nuanced exploration of 1950s South Korea, using wheat flour — a central commodity in US aid — as a focal point to unravel complex political dynamics. It challenges the traditional binary narrative of authoritarianism versus liberalism, demonstrating how the Rhee regime’s promotion of wheat flour consumption reflected multifaceted strategies of corruption. This article underscores the unintended consequences of US aid, highlighting the intricate interactions between foreign assistance and local political, economic and social forces. By analysing the local responses to wheat flour distribution, it reveals how US aid, while aimed at bolstering anticommunism, inadvertently facilitated corruption and influenced public sentiment.
