Dude, WWII officially began in 1939 when Germany invaded Poland... the US didnt give a shit until December 1941 when our own soils got attacked... before that the US didnt want to get thier hands dirty, sure, we helped out by giving European nations military loans from afar... but if we really cared about ridding the world of Hitler at the time, dont you think we would of been at war from the jump in 1939? Hell, even Canada joined the war in 1939.
