The United States and Russia have not signed a new nuclear arms control agreement in a decade and the New START Treaty is set to expire next year if not extended. The development of so-called disruptive nuclear weapons technologies, such as hypersonic and autonomous capabilities, not explicitly addressed under existing treaties further complicates bilateral negotiations to reach agreement on a future for nuclear arms control. In this paper, we develop a set of criteria to assess the disruptiveness of these technologies and evaluate their implications on potential arms control mechanisms. We review historic and theoretical motivations for pursuing bilateral arms control and analyze the U.S. and Russian nuclear postures through public government documents. We consider three potential mechanisms for future nuclear arms control agreements and argue in favor of a U.S.-Russia co-sponsored treaty in an international forum to constrain the deployment of those nuclear technologies assessed to be disruptive to strategic stability.
