NSWG’s Story

Nuclear security is one of the most pressing challenges of our time.

The Nuclear Security Working Group (NSWG) promotes bipartisan discourse on critical nuclear security issues, ranging from 21st century nuclear deterrence to pragmatic nuclear diplomacy and preventing the spread of nuclear weapons. 



The NSWG is:


non-partisanEnsuring that the discussion of issues remains free of political affiliation and influence.


interdisciplinaryWith leadership comprised of senior government foreign policy experts, active and retired military officials, and leading national security scholars.

a wide-ranging network

a wide-ranging networkConnecting highly-respected experts and practitioners with experience serving both Democrat and Republican administrations and Congressional offices.

The NSWG holds frequent private meetings in a not-for-attribution setting. We create a forum for the nation’s leading experts to share information and perspectives and arrive at a stronger consensus on pragmatic responses to nuclear and national security challenges.

NSWG members have deep professional ties to Congress and the Executive Branch. We focus on bridging the partisan divide, promoting dialogue on pragmatic nuclear security policies in the national interest.
NSWG’s work is made possible by generous support from the Carnegie Corporation of New York and the John D. and Catherine T. MacArthur Foundation.
