Who Are Brazil's Enemies?
Brazil has no declared foreign enemies as of 2015. The country's military spending, which amounted in 2010 to 1.6 percent of its gross domestic product, is devoted to defense. However, Brazil does have a small number of transnational disputes involving Uruguay and Colombia, according to the Central Intelligence Agency.
The dispute with Uruguay is territorial, concerning ownership of Braziliera (Brasiliera) Island in the Quarai (Cuareim) River. This is a question of where each country's political boundaries end. Firearms and narcotics are also smuggled in the Uruguay-Brazil border region.
Brazil's dispute with Colombia is the smuggling of narcotics between Brazil and Venezula, as well as the paramilitary activities in this border region, notes the Central Intelligence Agency.
