A resolution urging the United States to lead a global effort to halt and reverse the nuclear arms race.

S. Res. 323 is a Senate resolution urging the United States to take a leading role in a global effort to halt and reverse the nuclear arms race. It frames nuclear weapons as an existential risk and calls for renewed, good-faith diplomacy with other nuclear-armed states to halt further buildup, pursue verified reductions, and move toward disarmament. The resolution outlines concrete policy aims for the United States and the international community, including renouncing first use, reducing escalation risks, ending certain postures and modernizations, maintaining testing moratoriums, and protecting affected communities. It also emphasizes a just economic transition for workers and communities tied to the nuclear weapons program. As a resolution, it expresses the Senate’s position and guidance for the executive branch; it does not itself authorize spending or create binding legal obligations. Key elements include engaging all nuclear-armed states in verifiable reductions, pursuing new arms control with Russia, seeking mutual risk-reduction with China, ending hair-trigger alert, limiting or stopping new weapons programs, preserving the testing moratorium, addressing environmental remediation and health care for those affected, and planning a fair transition for workers and communities dependent on nuclear activities. The bill references the NPT, CTBT, and related treaties as scaffolding for these goals and reiterates concerns about modernization costs and treaty dynamics.
