In a pathbreaking ethnographic analysis, Masco argues that the U.S. focus on potential nuclear apocalypse during the Cold War obscured the broader effects of the nuclear complex on American society. The atomic bomb, he demonstrates, is not just the engine of American technoscientific modernity; it has produced a new cognitive orientation toward everyday life, provoking cross-cultural experiences of what Masco calls a "nuclear uncanny." Revealing how the bomb has reconfigured concepts of time, nature, race, and citizenship, the book provides new theoretical perspectives on the origin and logic of U.S. national security culture. The Nuclear Borderlands ultimately assesses the efforts of the nuclear security state to reinvent itself in a post-Cold War world, and in so doing exposes the nuclear logic supporting the twenty-first-century U.S. war on terrorism.
