Recalling how their leak of the covert Zimmermann telegram with the German Empire promising to award the lost territories of Texas, Arizona and New Mexico to Mexico if they invaded the United States and created a new front in the Great War in early 1917 pushed the US to engage in World War I, British intelligence forged (see also here and here) and publicised counterfeit attack plans allegedly by Nazi Germany for Central and South America—still very much considered within the US bailiwick as part of the Monroe doctrine—to motivate the administration of FDR to abandon its policy of neutrality in 1941 as Axis forces reached the French coast. The operation likely conceived by Canadian veteran flying ace and spymaster William Samuel Stephenson, responsible for British security on the continent who oversaw covert intelligence and propaganda efforts in South America, originally intended to leave a copy of the map in somewhere in Cuba in the hopes that American authorities would come across it of their own accord but it appears that Britain presented it to Roosevelt through intelligence channels directly, reportedly seized from a diplomatic courier in Buenos Aires. Presented to the American public as cautious not authentic bur rather secret (note the marking GEHEIM), it is unclear if the president was aware of its true nature.
