The threat posed by nuclear weapons is changing and policy-makers are struggling to keep up. As the Non-Proliferation Treaty review conference approaches, it is clear that the nuclear security field needs a new way of thinking. Nuclear-weapon states are expanding their arsenals and non-proliferation efforts have faltered: it is estimated that Tehran’s nuclear breakout time is now less than a month away, following Donald Trump’s unilateral withdrawal from the Iran deal in 2018 that had extended that timeline to 12 months.This week on War & Peace, Olga Oliker and Special guest-host Ali Vaez, Crisis Group’s Iran Project Director, are joined by Dr Emma Belcher, President of Ploughshares Fund, to ask whether and how bold innovation can solve some of these intractable challenges. They discuss the ways in which policy debates have, or have not, evolved, the continued dominance of deterrence theory and the wave of new, diverse and creative thinkers challenging stale ideas. They also discuss the resumption of negotiations between Iran and the P5+1, prospects for other non-proliferation efforts and hopes for a nuclear-weapon-free future.Make sure to learn more about Dr Belcher’s work at Ploughshares Fund by visiting ploughsares.org and listening to Ploughshares podcast Press the Button.This episode is part of our continuing War & Peace sub-series on nuclear weapons and strategy.
