This bill calls on the Massachusetts congressional delegation to support the Treaty on the Prohibition of Nuclear Weapons, highlighting the significant threat posed by the existence of over 12,000 nuclear weapons globally. It emphasizes the longstanding concerns of the commonwealth's residents regarding nuclear threats, as demonstrated through various local resolutions and legislative actions. The bill references the commonwealth's historical role in nuclear disarmament efforts, particularly during the 1980s, and notes that the Treaty has been ratified by 70 countries since its enforcement on January 22, 2021.

Furthermore, the bill urges Massachusetts lawmakers to co-sponsor House Resolution 317 and Senate Resolution 323, which align with the national Back from the Brink platform. This platform advocates for a series of measures aimed at reducing the risk of nuclear war, including the elimination of nuclear arsenals, renouncing first-use policies, and curtailing the President's unchecked authority to launch nuclear attacks. The bill concludes by directing the Senate clerk to send copies of the resolutions to key federal leaders and the governor of Massachusetts.
