So, I'm having a little bit of trouble with finding stuff to support this prompt:

Most Americans believed in 1940-41 that war, if it came, would come in the Atlantic with Hitler's Germany. Instead, it came in the Pacific with Japan. Why were Americans so surprised by the Japanese attack?

All I can really think of or find in my book is that even during the war America was trading supplies like oil, iron, ect. with Japan...so maybe Americans were less worried about a blowup with them? I don't really know what else though.

Thanks
