In the fall of 1941, the American public was still against joining the war. But while FDR was focused on Europe, Japan was increasingly aggressive in the Far East and planned to attack us.

The Japanese sunk most of the American fleet stationed at Pearl Harbor (several big boats were saved due to their tardiness in arriving to their port). FDR addressed Congress the next day, describing December 7th as "a date which will live in infamy."<ref>http://www.let.rug.nl/usa/P/fr32/speeches/ph.htm</ref> | In the fall of 1941, the American public was still against joining the war.
