Hmmmm well I don’t know but I guess I’ll go with A
Some people where for it while other thought that it was a wast of time people back then didn't want Americans to loos people over silly disputes
The answer to this is African Americans.
Back around World War II they mostly pay attention to the war so the whole racism left African Americans alone because around that time they didn't quite care for that too much because they mostly want to keep on the whole war thing. Around that time the U.S was just about getting ready to get involved.
Hope this helped :)
Have a great day
Maybe the us will think that the Germans are going to attack them more
