An oganization I support and greatly respect is the Institute for Global Engagement. The IGE is a “think tank” with the goal of fostering theological reflection on and faith-based engagement in international affairs. They publish an excellent journal, The Review of Faith and International Affairs.
I particularly like the IGE’s approach to Islam. Unlike much of American Evangelicaldom, the IGE doesn’t reduce Islam to radical jihadism. At the same time, the IGE’s approach is realistic about the problems of radical Islam and the difficulties inherent in promoting the development of moderate Islamic societies. Some good articles from IGE’s site about this are here, here, and here.
