the presidency of eurico gaspar dutra (1946–51) opened a brief period of democratic rule after ousting of getúlio vargas. during the dutras administration, brazil's foreign policy was aligned closely with that of the united states. dutra outlawed the brazilian communist party (pcb) in 1947 and broke off relations with the soviet union. in contradiction to the economic nationalism of his predecessor, he opened the country for foreign, mostly u.s., investments. getúlio vargas's return to power in 1951—now in democratic fashion—however, signaled a cooling of relations and a return to economic nationalism. vargas blamed the u.s. for his ouster in 1945 and appealed to brazilian nationalism, a sentiment that was growing in many sectors, including the armed forces. in the new vargas mandate the old tensions with foreign capital returned in full force—specially after he tried to implement a bill that precluded 90% of the capital produced in the country from being sent to international banks. as a result of the many scandals in his second mandate—corruption scandals, tensions with the military etc.—vargas killed himself in 1954. he left behind a suicide letter, the "carta testamento", in which he points to media denigration and pressure from foreign banks as the blame for his depression and death.
