If you would like to see how the home front perceived the build up and the war, look through the Google books of Life. This one features the US Navy in 1940. One picture shows the Arizona in maneuvers.
Good link to the LIFE magazines on Google. I just lost an hour strolling through various early 40's issues. Its the non-war stories and even the ads that give a real flavor for that time on the home front.
Thanks
