Ground Zero Center for Nonviolent Action (GZ) offers the opportunity to explore the meaning and practice of nonviolence from the perspective of deep spiritual reflection, providing a means for witnessing to and resisting all nuclear weapons, especially Trident. GZ is located in Poulsbo, Washington, next to Naval Base Kitsap-Bangor, the largest concentration of deployed nuclear weapons in the United States and home to eight of the US Navy's Trident ballistic missile submarines.
