Brazil–United States relations are the bilateral relations between the Federative Republic of Brazil and the United States of America. Relations have a long history, with the United States being the first country to recognize Brazilian independence and Brazil the only South American nation to send troops to fight alongside the Allies in World War II. Though never openly confrontational towards each other, relations between the two countries have been relatively distant with brief periods of cooperation in the past. However, in recent years, the two have become more aligned on tackling humanitarian issues such as HIV/AIDS and poverty, establishing a growing partnership. While Brazil–US relations have been strengthed significally following the election of Dilma Rousseff as president of Brazil in 2011, and the recent deterioration of Brazil-Iran relations, there has been significant rupturing in Brazil-U.S. relations, over the revelation of US mass surveillance programs in Brazil, specifically allegations of US spying on President Rousseff. This rupture has healed somewhat in 2014 after Dilma Rousseff realized that President Obama was not directly involved in the spying.
In addition, the two countries share membership in a variety of international organizations, including the United Nations, the World Trade Organization, the Organization of American States, the G8+5, and the Group of 20. Brazil is one of the most pro-American nations in the world. According to a global opinion poll, 62% of Brazilians viewed the U.S. favorably in 2010, increasing to 73% in 2013; additionally, as of 2013, 83% of Brazilians view U.S. influence positively. However, these polls were conducted prior to revelations of U.S. espionage to the Brazilian public.[1] In another poll conducted at the end of 2013, 61% of Americans view Brazil favorably, with 15% viewing it unfavorably.[2]
