Mexico’s views of the United States have been characterized as stridently anti-American, but recent policy changes in Mexico-culminating with the North American Free Trade Agreement (NAFTA)-mark a fundamental transformation in the relationship. This thoughtful and original work answers questions about the impact of these policy shifts on Mexican nationalism and perceptions of the United States. Have popular and elite views changed? Has the government’s anti-American rhetoric become anachronistic? What has been the effect on Mexican national identity? As the only developing country to have entered into a free trade agreement with a developed country, Mexico offers a unique and invaluable case study of the impact of globalization on a nation and its national identity. Exploring Mexico’s experience also allows us to consider how other countries perceive the United States, especially in the post-9/11 climate. Analyzing the diversity of Mexican views of the United States, Gringolandia contributes a rich and nuanced dimension to our understanding of contemporary Mexico and Mexicans’ feelings about the vital cross-border relationship.
