According to Samuel Huntington’s seminal 1993 essay, The Clash of Civilizations, world politics is entering a new phase, in which the great divisions among humankind and the dominating source of international conflict will be cultural. Civilizations—the highest cultural groupings of people—are differentiated from each other by religion, history, language and tradition. In the resulting era of cultural conflict that is emerging, the United States must forge alliances with similar cultures and spread its values wherever possible. In Huntington’s final analysis, the West must be accommodating if possible and confrontational if necessary; moreover, all civilizations will have to learn to tolerate each other. This collection includes a series of responses to Huntington’s original essay by eminent writers in the field.
