The Council on Foreign Relations (CFR) was established in 1921, with support from the Rockefeller family, to provide a forum for government officials, corporate executives, journalists, students, and other interested parties to study and discuss world issues and the related impact on American foreign policy. The independent, nonpartisan council publishes Foreign Affairs, a magazine that comes out six times a year, along with books and studies by its own scholars. It also sponsors task forces and hosts meetings attended by world leaders, government officials, and diplomats. Prospective members must be US citizens (native-born or naturalized) and are nominated by an existing member. CFR currently has about 4,700 members.
