It's not that easy. You loose knowledge and vendors and people. Going from 0 unit production per year to 10 per year is more difficult than going going from 10 per year to 10000 per year.
Pre-massive-globalization, we had no problem gearing up for WW2. Our industrial capacity was largely in-house. There were some things like rubber that were off-shore, but generally the industrial toolchain was domestically produced.
Nowadays, many domestic industrial producers rely heavily on these (bloated) military contracts to maintain relevance in a globalized industrial setting where the center of gravity for a lot of heavy industry and tool production has shifted to Asia.
I love international trade and I'm skeptical of military spending (and even more so of military adventurism), but this effect should be kept in mind when making trade policy. The military-industrial complex is keeping alive much of our industrial know-how that would otherwise be entirely be off-shored and retired domestically.
It would be amazing if WWIII broke out and we had to call on Tesla to manufacture tanks.
You may lose the ability to make widgets because it's easier/cheaper to buy them from another country, but in theory, you make it up by selling them sprockets, and through the overall economic gains.
This fact is supposedly a part of the reason the f35 went to lockheed vs boeing.
