Walter Russell Mead discusses his book God and Gold: Britain, America, and the Making of the Modern World.

Mead, the Henry A. Kissinger senior fellow for U.S. foreign policy at the Council on Foreign Relations and one of the country's leading students of American foreign policy, contends that the key to the predominance of the two countries has been the individualistic ideology of the prevailing Anglo-American religion. Mead explains how this helped create a culture uniquely adapted to capitalism, a system under which both countries thrived. We see how, as a result, the two nations were able to create the liberal, democratic system whose economic and social influence continues to grow around the world.

According to Mead, the stakes today are higher than ever; technological progress makes new and terrible weapons easier for rogue states and terror groups to develop and deploy. Where some see an end to history and others a clash of civilizations, Mead sees the current conflicts in the Middle East as the latest challenge to the liberal, capitalist, and democratic world system that the Anglo-Americans are trying to build. What we need now, he says, is a diplomacy of civlizations based on a deeper understanding of the recurring conflicts between the liberal world system and its foes.
