The Clash of Civilizations is an influential and controversial work in the fields of international relations theory and political science. It asserts the primacy of cultural identity in shaping global order and disorder. At the heart of Huntington’s argument lies a fundamental reorientation of global conflict away from ideology and economics and toward culture and civilization. 

Huntington dismisses the universalist assumptions embedded in liberal internationalism, especially the idea that Western values are globally desirable and destined to prevail. Some critics have argued, however, that civilizations in his schema are treated as monolithic entities with coherent values and stable identities, sharply divided from one another and predisposed to competition. This essentialist framework overlooks the hybridity, contestation, and internal diversity that characterize any large-scale cultural formation. Islamic, Western, or Sinic civilizations are not singular actors but are riven by ideological disputes, class hierarchies, religious differences, and shifting geopolitical interests. By ignoring these fissures, critics have suggested, Huntington constructs an artificial geography of culture that tends to flatten complexity in the service of a binary logic of conflict.

Huntington’s concept of civilization could also be interpreted as naturalizing political conflict. By casting cultural difference as the primary fault line in international affairs, critics have said that he risks presenting violence as the inevitable outcome of cultural proximity or misunderstanding. This has the effect of displacing other explanations for conflict, such as colonial legacies, economic inequality, and political repression. 

After the September 11th terrorist attacks, Huntington’s thesis was widely invoked in Western political discourse to frame the attacks and the broader struggle against terrorism as confirmation of a civilizational conflict between Islam and the West. In this context, The Clash of Civilizations served as both diagnosis and justification: It helped explain a perceived threat and legitimated an aggressive foreign policy response. In reducing complex geopolitical dynamics—such as US intervention in the Middle East or the rise of international extremist networks—to civilizational friction,  critics argued that Huntington’s thesis became a tool for reasserting Western primacy under the guise of cultural defense. While Huntington does not explicitly argue for the superiority of Western civilization, his argument implicitly privileges the West by framing it as the benchmark of order and the primary target of hostility. While he calls for cultural pluralism, this pluralism is couched in terms of civilizational boundaries and the imperative for the West to remain strong and distinct. 

Huntington’s framework is also significant within the context of contemporary populist and nationalist movements around the world. The idea that cultures are fixed and incompatible underpins many exclusionary political ideologies, from anti-immigrant rhetoric in Europe to Hindutva nationalism in India. In this sense, The Clash of Civilizations could be seen as justifying a defensive and often authoritarian view of politics, one that elevates cultural homogeneity and sovereign insulation over democratic pluralism and global cooperation.
