"Vietnam led other humanitarian organizations to distance their work from American foreign policy. Since World War II, agencies such as Catholic Relief Services, CARE, and Church World Service viewed their work either as supportive of America's anti-Communist position or at least neutral in the face of international need. By 1965, however, as protest to the war escalated at home, many agencies realized that apoliticism was impossible. Any participation in Vietnam had become a politically partisan act. Vietnam ended the notion of apolitical humanitarianism and cozy church-state partnership overseas. Several ecumenical agencies pulled out of Vietnam while others sought to protest and influence U.S. military action. As a result, they lost millions of USAID dollars."
