WWII comparison to today is not fair. We had the smallest military in the Industrialized World at the start of the war. Then we maintained a force that could fight a World War for the last 60 years. We could probably handle 6 Afghanistan conflicts with out affecting the home front. We are situated to fight 2 Desert Storm sized conflicts at one time.
If we did enter into a Full Scale War, it would take us years to burn through our current manufacturing capacity. Then you have to figure that we import nearly all of our consumer goods, that will take either a very long time to interrupt or hurt us fast if we go to war with China and Japan.
