During the five years in which he represented Brazil in the United States (under both the Cardoso and Lula presidencies), Ambassador Barbosa witnessed presidential elections that brought opposition parties to power in both the United States and Brazil, the 9/11 terrorist attacks, the outbreak of war in Afghanistan and Iraq, and the election of Luiz Inacio Lula da Silva.

In this memoir, translated from the Portuguese, he recounts the most significant regional and global issues that arose, alongside the domestic political conflicts within a divided North American society. Barbosa provides sophisticated analysis of economic relations during these changing times, and also explores the many US misconceptions about Brazil and the Latin American region.

From the privileged post of observation that an ambassadorship in the American capital represents, Barbosa had the exceptional opportunity over a considerable length of time to closely follow relations between Brazil and the United States. He witnessed relations evolve under two governments as they developed distinct foreign policies, which at times led to a breakdown in understanding between the two countries.
