In recent years, scholars have discovered that the American public responds to foreign policy issues on the basis of fairly stable broad orientations toward international affairs, influenced by a number of demographic, ideological, and partisan factors. Although there has been much recent speculation about the role that religion plays in shaping such orientations, there are very few empirical analyses of that influence. In this article, I use the 2012 Chicago Council on Global Affairs survey to classify American religious groups on Wittkopf ‘s (1990) classic dimensions of foreign policy attitudes: militant internationalism and cooperative internationalism. I find rather different religious constituencies for each perspective, with Evangelical Protestants and religious traditionalists from other faiths most supportive of militant internationalism, while ethnoreligious minorities and religious modernists are most likely to back cooperative internationalism.
