Final Presentation: Iranian Nuclear Hedging After the JCPOA

As successive rounds of negotiations fail to make progress, it is becoming increasingly clear that the JCPOA with Iran is a moribund agreement. Nevertheless, it is not at all clear that Iran has decided to produce a nuclear weapon. My research this summer explores one possible strategy Iran might pursue: hedging its atomic bet by enhancing non-civilian nuclear technology without attempting to build or test an actual weapon. A particularly aggressive form of this strategy would involve advancing up to the threshold of weaponization, where Iran could build a weapon within months of a leadership decision to become a nuclear weapons state. My ongoing research   studies this strategy on three prongs: First, I have been researching the technical basis of Iran’s enrichment program and its abandoned attempt to build a nuclear weapon before 2003 to understand how Iran could continue technical progress without building a weapon. Second, I have been examining historical parallels to Iran’s situation to see what paths advanced hedging states have taken. And third, I have been reviewing the literature on hedging, deterrence, and proliferation to ascertain some possible consequences of an Iranian hedging strategy.
