Iran's pursuit of a civilian nuclear program raises concerns over the potential security threat it poses to the United States and its Middle East allies. The US suspects that Tehran's lack of compliance with the Nuclear Non-Proliferation Treaty signifies its intention to build atomic weapons. This article aims to examine the strategies implemented during the presidencies of Obama, Trump, and Biden to prevent Iran from acquiring nuclear arsenals. Employing a constructivist theory, the study examines how each administration constructed identities, perceptions, and norms regarding Iran, and how these shaped their diplomatic approaches. Drawing on a comprehensive data of primary and secondary sources, this research sheds light on the identities, perceptions, and power dynamics shaping US–Iran relations.
