If Germany had attacked the US in 1939 before we got our war legs under us, we would have been defeated. As it was the nation was very pacifist and isolationist.
No way.
I wouldn’t say we were Pacifist at all, not like “Hippy” Pacifist, Isolationists just thought it wasn’t our business.
But I guarantee if the Germans came after us, there would have been no Pacifism. Our industry would have ramped up on a dime, the Germans at best could have gained a beachhead or two, but they would have been eventually routed.
What were they going to attack us with?
