As one of its first decisions regarding security policy, the Biden administration agreed to extend the New Strategic Arms Reduction Treaty (START) for five years with no conditions. New START represents one of the last remaining vestiges of international arms control architecture and one of the few areas of potentially productive U.S.-Russian dialogue in an otherwise toxic, distrustful bilateral relationship. Yet the security environment has drastically changed since New START was negotiated in 2010. The treaty covers only a part of the “security equation” wherein missile defense, new weapons systems, space-based assets, and advanced technologies are not subject to formal arms control agreements. Both Moscow and Washington—though to different extents—have grounds to be concerned about the nuclear capabilities of third countries that are not party to existing arms control arrangements.
