Foreign Affairs - Us and Them - Jerry Z. Muller: “Summary: Americans generally belittle the role of ethnic nationalism in politics. But in fact, it corresponds to some enduring propensities of the human spirit, it is galvanized by modernization, and in one form or another, it will drive global politics for generations to come. Once ethnic nationalism has captured the imagination of groups in a multiethnic society, ethnic disaggregation or partition is often the least bad answer.”
