Since the ratification of of the New Strategic Arms Reduction Treaty (New START) in 2010, the NSWG has worked with senior representatives from the White House, Congress, and the larger policy community to elevate the discussion of U.S. nuclear security challenges and to redress the polarization and relative lack of nuclear expertise that is hindering effective policymaking. NSWG leaders participate in meetings and conferences designed to educate a wide variety of foreign policy professionals about the evolving nuclear threat environment and build consensus within the policy community on the most effective ways to meet the challenges of the 21st century.
