Through grassroots organizing, policy advocacy, and community education, Massachusetts Peace Action prioritizes nuclear disarmament, advocates for non-military solutions for international issues, and commits to ending wars while preventing new ones. MAPA does much of its work through volunteer-driven working groups, e.g. Nuclear Disarmament, Racial Justice/Decolonizarion, Middle East, Climate and Peace, which meet monthly or more frequently.
