It's weird I was just watching The World At War documentary this morning and it was the episode about how the U.S ended up entering the war, it implied that Roosevelt -God I hate that guy- really wanted to go for the aid of England but pubic opinion was strongly opposing to the idea of getting involved in what the U.S media called a "European War", they have so much awesome footage from the American presidential elections at the time and the one card that guys running against Roosevelt kept playing is that the U.S doesn't need to enter a war now, especially if we have nothing to do with it, one runner went as far as saying in a rally "In the past we had to deal with Europe led by England and France and in the future we might have to deal with Europe led by Germany, it's as simple as that".
They had footage of people on the street, collecting public opinion, you heard stuff like "Let them figure it out for themselves" and "I'm gonna watch it on the news, that's as far as we wanna go with that war"
