Williamson supports the creation of a United States Department of Peace to aid in her proposed redesign. Williamson supports decreasing the military budget and redirecting those funds toward peacebuilding and peace maintenance efforts e.g. mediation, diplomacy, humanitarian aid, post-conflict transitional justice, and "on-the-ground programs." She also supports maintaining a budget that would not impede military preparedness, while investing in a "sustainable society" inclusive of the development of clean energy and green manufacturing, retrofitting buildings and bridges, economically empowering women, and educating children. Williamson supports military engagement in the event that a NATO ally is threatened, in the event that the United States is under threat of attack, or "when the humanitarian order of the world is at risk." Williamson supports the creation of a program of which every citizen, between 18 and 26, can perform one year of voluntary National Service –– helping schools, hospitals, infrastructure, sustainability, regenerative agricultural projects, the military, the Peace Corps –– that can be remunerated for housing, "basic costs," or financial support for higher education. Williamson supports returning dominant control of the Black Hills to the Sioux Nation, halting construction of the Keystone Pipeline, recognizing tribal sovereignty over their territory. She also supports increasing funding to Native lands’ justice systems, protecting tribal sovereignty and governance, and protecting Native religious freedom. Williamson has expressed support for "rethinking treaties" and continuing annual tribal nations' summits in Washington D.C.  Williamson supports the distribution of $200-$500 billion in reparations for slavery, spread across 20 years for "economic and education projects," to be disbursed based on the recommendation of a selected group of black leaders. In taking this position, Williamson became the only candidate to ever submit a detailed plan for reparations for black Americans. Williamson, who first expressed her support of reparations in her 1993 book, "Illuminata" –– advocating that the U.S. will not reconcile its racial and economic divide without them has said of the policy proposal –– states that her policy on reparations is not part of "a black agenda,"  Williamson supports abortion access, services and choice. She also supports the Supreme Court's decision on Roe v. Wade.  Williamson deems climate change to be "the greatest moral challenge of our generation." She claimed support for the Green New Deal, immediate re-entry into the Paris Climate Accords, and has stated that she would be willing to support the Trans-Pacific Partnership if it included greater protections for workers and the environment.
