Brookings Institution
The Brookings Institution is a nonprofit public policy organization based in Washington, DC. Our mission is to conduct high-quality, independent research and, based on that research, to provide innovative, practical recommendations that advance three broad goals: strengthen American democracy; foster the economic and social welfare, security and opportunity of all Americans and secure a more open, safe, prosperous and cooperative international system.

Center for American Progress
The Center for American Progress is a progressive think-tank dedicated to improving the lives of Americans through ideas and action.

Council on Foreign Relations
The Council on Foreign Relations is an independent, nonpartisan membership organization, think tank, and publisher dedicated to being a resource for its members, government officials, business executives, journalists, educators and students, civic and religious leaders, and other interested citizens in order to help them better understand the world and the foreign policy choices facing the United States and other countries.

Ethics and Public Policy Center
The Ethics and Public Policy Center was established in 1976 to clarify and reinforce the bond between the Judeo-Christian moral tradition and the public debate over domestic and foreign policy issues.

Pew Forum on Religion and Public Life
The Pew Forum on Religion & Public Life, launched in 2001, seeks to promote a deeper understanding of issues at the intersection of religion and public affairs. The Forum pursues its mission by delivering timely, impartial information to national opinion leaders, including government officials and journalists. As a nonpartisan, non-advocacy organization, the Forum does not take positions on policy debates.
