The thesis of this provocative and potentially important book is the increasing threat of violence arising from renewed conflicts between countries and cultures that base their traditions on religious faith and dogma. This argument moves past the notion of ethnicity to examine the growing influence of a handful of major cultures--Western, Eastern Orthodox, Latin American, Islamic, Japanese, Chinese, Hindu, and African--in current struggles across the globe. Samuel P. Huntington, a political scientist at Harvard University and foreign policy aide to President Clinton, argues that policymakers should be mindful of this development when they interfere in other nations' affairs.
