Overlooked in today's bloody headlines is Mexico's fundamental transformation. In over three short decades it has gone from a poor to a middle class nation, a closed to an open economy, an authoritarian to a vibrant (if at times messy) democracy, and a local to an increasingly binational society. But while things are much better than portrayed, Mexico does face a true security challenge. It stands at a crossroads. It can follow a path toward a top ten economy, an open democracy, and a leading world voice, or one that spirals down into drug-fueled corruption and violence. Today's choices will define not only Mexico's future, but also that of the United States. Perhaps no other nation is as indelibly intertwined with our economy, society, and daily lives. What happens in Mexico will affect the United States for decades to come.

Two Nations Indivisible tells the story of the making of modern Mexico, and what it means for the United States. Recounting the economic, political, social, and security changes of the last thirty years, it provides a roadmap for the greatest overlooked foreign policy challenge of our time -relations with our southern neighbor. For the good of both countries, it argues against walling the United States off from its neighbor; and instead for investing finally in a true partnership.
