Last year, Scott Sagan declared – on H-Diplo – that we are in the midst of a renaissance in nuclear studies, driven by first-rate work by younger scholars. Two qualities in particular mark this scholarship. First, many of these young scholars combine both methodological innovation and rigor while engaging new archival sources. Second, these scholars are unafraid to challenge long-held conventional wisdoms about the nuclear age. The three commentators to this forum – a roundtable on Andreas Wenger and Roland Popp (eds.), “Special Issue: The Origins of the Nuclear Nonproliferation Regime,” in The International History Review — are exemplars of these trends. Eliza Gheorghe has mined new sources to explore the previously unknown and fascinating history of Romania’s nuclear program, in the process generating important insights into nuclear dynamics between superpowers and smaller states. Nicholas Miller has identified the key moments in United States nuclear nonproliferation policy, helping us understand the motivations and tools driving these efforts. Jane Vayman has built upon recent historical research to model the causal dynamics behind the surprising superpower collusion to stem the spread of nuclear weapons. As their previous work and their reviews here reveal, all three are equally conversant in the most recent historical scholarship and the newest trends in international relations theory involving nuclear dynamics.
