This article examines Turkey's position as an aid recipient during the Cold War, benefiting from assistance provided by both the United States and the Soviet Union. Adopting a comparative approach, this study investigates the impact of these investments on the development of two major iron and steel plants: the Ere & gbreve;li Iron and Steel Plant (ERDEM & Idot;R), constructed with American financial and industrial support, and the & Idot;skenderun Iron and Steel Plant (& Idot;SDEM & Idot;R), established with Soviet assistance. Both projects sparked political controversy in Turkey during the 1960s and 1970s, shaped not only by the ideological rivalries of the Cold War but also by material realities on the ground. In terms of the conditions attached to aid, transfer of technology, and ownership structures, there were significant differences between the support offered by the capitalist and socialist countries. These differences were evident in the cases of ERDEM & Idot;R and & Idot;SDEM & Idot;R, where two distinct models were used for practical testing. This article argues that comparing the construction and operation of these plants provides valuable insights into the nature of Cold War aid and contributes to the broader global literature on the subject.
