The Brazil-United States Political-Military Agreement (Portuguese: Acordos de Washington, Washington Accords) which came into an effect on 23 May 1942, was a prelude to formal entering of Brazil into World War II. Its implementation was carried out by the Joint Brazil-United States Military Commission (JBUSMC).[1][2] It was a result on a series of consultations in Rio de Janeiro since 1941, during which a number of various political and business decisions were made. The term "Washington Accords" may refer to these preceding negotiations as well.
