Foreign Affairs – God’s Country? – Walter Russell Mead
“Religion has always been a major force in U.S. politics, but the recent surge in the number and the power of evangelicals is recasting the country’s political scene — with dramatic implications for foreign policy. This should not be cause for panic: evangelicals are passionately devoted to justice and improving the world, and eager to reach out across sectarian lines.”

Walter Russell Mead is Henry A. Kissinger Senior Fellow for U.S. Foreign Policy at the Council on Foreign Relations

A fantastic summarization and description of the power structure of modern (and some past) American Christianity and how it plays into politics and the international arena.
