It should take large number of bombers or ICBMs to render the US unable to build or repair her Navy.
In World War II we hijacked most of the industrial base for the war machine. After the war, there was incentive to be certain that the US was capable of outfitting the Armed Forces regardless of whether manufacturing slowly shifted overseas.
South Korea, Japan, and Taiwan are too geographically close to a number of likely antagonists in the next global conflict. In the latter case, the distance might be negative.
They may be occupied or their industry bombed to dust as the opening moves in a protracted conflict.
There is something to be said for the DoD to effectively be paying rent (or a retainer, if you prefer that analogy) to Western Hemisphere manufacturing, with a large fraction in the continental US.
