The chapter begins with a brief history of lukewarm Indo-US relations during the Cold War and the reasons for the lack of depth. The chapter then traces the converging trends including the collapse of the Soviet Union, India’s neoliberalization, India’s 1998 nuclear tests, the Indian American diaspora, the rise of China and re-emergence of Russia that resulted in movement towards a Indo-US strategic embrace undergirded by a grand nuclear accommodation of India’s hitherto sanctioned nuclear programme culminating in the July 18, 2005 joint statement. Multiple narratives of the nuclear deal’s origins are explored and the more salient ones are highlighted. The chapter ends with a brief summary of the constructivist Science and Technology Studies (STS) approach’s key principles such as thick description, multidimensional narration and rejection of technological determinism.
