Grim Economic Realities
Aimlessly tooling around the Internet brought me to this page about the inevitability of an American victory against Japan in WWII.
The author looks at plain economics to show that the moment they launched an attack against America, the Japanes were doomed to lose. He shows how the Great Depression meant we had massive amounts of "slack" in our economy that could be taken up and directed into the war effort, where Japan's economy had almost none.
He also notes that by the end of the war, our navy was larger than every navy in the world combined, a staggering thought.
There's a lot there that benefits a more than casual read. Take a look.
