" What, however, makes culture and ideology attractive? They become attractive when they are seen as rooted in material success and influence. Soft power is power only when it rests on a foundation of hard power. Increases in hard economic and military power produce enhanced self-confidence, arrogance, and belief in the superiority of one’s own culture or soft power compared to those of other peoples and greatly increase its attractiveness to other peoples. Decreases in economic and military power lead to self-doubt, crises of identity, and efforts to find in other cultures the keys to economic, military, and political success. "

― Samuel P. Huntington , The Clash of Civilizations and the Remaking of World Order
