Lesson plan

Plan Rubber

An operation with the codename Plan Rubber was the amphibious component of the Joint Basic Plan for the Occupation of Northeast Brazil, J. B., Serial 737, dated 21 December 1941. This would have been a United States military invasion of the northeastern coast of Brazil, through the beaches of Natal, during World War II. The plan was never carried out due to successful diplomatic initiatives with Brazilian President Getúlio Vargas. Brazil's northeastern salient or bulge is where South America is at its closest to Africa, and thus offered American strategists an air route through the Atlantic Ocean and a platform for maritime patrol in the Battle of the Atlantic. Since the late 1930s, the region was part of the US's defensive perimeter as defined by its military planners. Since 1941 the Brazilian Armed Forces were reinforcing their hitherto almost undefended coastline north of Rio de Janeiro, but officials in the American Franklin D. Roosevelt administration deemed these defenses insufficient and feared the Brazilian Estado Novo dictatorship would align itself with the Axis powers or be overthrown by a pro-Axis coup. A land intervention in Brazil was studied by previous plans such as May 1940's "Pot of Gold" and November 1941's "Lilac". Plan Rubber had its main goal in the city of Natal, which would be occupied by the US Marine Corps.…
