The Council for the National Interest (CNI) opposes Israel's occupation of Palestinian lands since the Six Day war.[15] The Mennonite Central Committee (MCC) looks for economic means to end the occupation of what it calls "Palestine/Israel." It suggests an economic boycott by all Christians of Israel, including divestment of stocks of companies that do business with Israel.[16] MCC activist Alain Weaver has advocated a One-state solution, writing "Might not a bi-national future in one state be one in which Palestinians and Israelis alike both sit securely under vine and fig tree?"[17] The American Friends Service Committee (AFSC) opposes settlements in the occupied territories.[18] In December, 2008, AFSC wrote an open letter to President Obama, urging American pressure to stop the war in Gaza and to open negotiations with Hamas.[19] As a Quaker organization that opposes all war, AFSC has been active in Israel and Palestine, supporting pacifism, conscientious objectors, and nonviolence.[20] In 2004 the Presbyterian Church (U.S.A.), which had long opposed the occupation of Palestine, called for a "phased selective divestment in accordance with General Assembly policy on social investing."[21]
