"Nazi meeting in Puerto Varas, Chile." Archivo Nacional De Chile.
By 1939, Germany had invaded Czechoslovakia and Austria, but with its current resources could not stage attacks on major countries. Hitler thus set his sights on neutral South America, which would provide Nazi forces with raw materials and serve as a base for underground operations.
"Any South American country, in Nazi hands, would always constitute a jumping-off place for German attack on any one of the other republics of this hemisphere."
-Franklin D. Roosevelt, "The Great Arsenal of Democracy", 1940.

Johannes Siegfried Becker, professionally known as Sargo, was a spy of the Nazi intelligence agency Sicherheitsdienst. Sargo’s assignment was to gather intel on technological advancements made by the US and British and sway South American politics towards the Nazis. This espionage, codenamed Operation Bolivar, was one of many designed to convince the continent to remain neutral instead of declaring support for the Allies.
