What did "losing the war" mean in practice for the US, was it basically Europe becoming German? And whatever "losing the war" meant, did the US have a plan for what to do then?
Follow up questions: if the US had started losing ground on the pacific side, would they have pulled (some) forces back out of Europe to protect the Western Coast?
In a similar vein, how far did Japan want to go against the US? I apologize if this is out of place, I am not familiar with the pacific campaign at all.
Follow up: Did Germany have plans for invading North America?
