American Idealism

It seems that America tended to be rather idealistic about its expectations for war. First it thought it could just ignore it all and hope "the storm clouds" "far across the sea" would just dissipate and not effect it. Then Americans figured they'd just profit off of it much like the last war, only the President was more one-sided in who we would profit off. No one seemed to realize what an economic threat a unified Nazi Europe would be. With the sort of trade controls and tariffs they would be able to levee against us, no doubt America would have quickly come to regret ignoring A German victory in Europe. Aren't we glad we never let it get to that? If anyone is interested in these sort of what ifs? I have read quite a lot of the literature out there on the subject, and could probably point you to a book or two. For instance, in The Third Reich Victorious 10 different scenarios are presented on how the war may have turned out differently. There are others out there as well, if you wanted to look more into the social aspect of that or the Eastern Front.
