America doesn't have the manufacturing base it had in WWII. Then, it took months or even years to ramp up the existing manufacturing to wartime capacity. Now a lot of America's manufacturing has been outsourced to China and other far eastern/southern Asian countries. A modern war between superpowers is likely to be won or lost in a week or two at most even without involving nukes, long before major resupply of equipment is even needed.
