not really. we turned up the industry to produce more than the world combined in under 2 years with fewer resources and way less capital during WW2.

We currently have thousands of vacant factories and hungry rust belt communities eager to jump on such a move. It’d be an easier transition than you think. A few years of annoyance and stagnation and what not, but considering we can get most anything from somewhere else, it’d for the largest part be a management scramble and doubling of costs until we are back on line.
