Very good point. We outsourced most all manufacturing. In a pinch, we now cant even repurpose existing lines to make what we need. All an enemy need do is cut off any supply line from Mexico and we're toast. I need not mention the supply lines in Asia because that would take minimal effort to stop.
We don't mine coal or other resources critical to defense. So even if we could conceivably manufacture something, we have no raw materials.
This little blurb of info should really alert people for more reasons than this conflict, but it wont.
