Discoveries of oil off Brazil's coast were cited as justifications for increasing Brazil's navy. While the oil finds will almost certainly increase Brazil's future prosperity, the US sought to turn the strategic dialogue in Brazil away from fantasies that another country — potentially the United States — would try to seize the oil fields to a productive discussion of energy security and the importance of maintaining freedom of the seas. The April 2008 announcement of the reactivation of the US Fourth Fleet caught Brazil by surprise and provoked much negative commentary. Even many Brazilians not prone to accept the wild-eyed theories of U.S. intentions to invade the Amazon suspected that the announcement, coming as it did on the heels of President Lula' s announcement that Brazil had discovered more oil off the Brazilian coast, could not have been a coincidence.
