About the event: Since the mid-2010s, scholars and analysts have declared the emergence of a dangerous ‘new’ or ‘third’ nuclear age. Beyond academia, the concept of the new nuclear age is proving influential with policymakers in a range of countries. The new nuclear age is understood to be characterized by technological change, nuclear multipolarity, eroding constraints on the behavior and competition of nuclear-armed states, and the likely emergence of new nuclear powers. That said, it remains unclear how we should understand the new nuclear age in broader terms: how new is it and does it require new theoretical frameworks to understand? Bell subjects the concept of the new nuclear age to scrutiny. He connects the discussion of the new nuclear age to ongoing but mostly separate debates about nuclear history and the ‘Theory of the Nuclear Revolution’ (TNR). The increasing body of literature challenging TNR reveals a more competitive, complex, and dangerous nuclear past than our prior understandings, but in doing so, it draws attention to continuities between the past and the emerging nuclear age. Bell then examines the empirical features thought to define the new nuclear age and show that many have historical precedent and do not require novel theoretical frameworks to understand. The new nuclear age may, therefore, be somewhat less new, though perhaps no less dangerous, than it appears.
