OK, I'll go to his defense.
Weapons themselves may not be imported, but quite a few electronic and sensor components already are. In many cases because they are simply not produced in this country.
DoD has no problem offshoring software development to India, even for weapons systems.
Even some of our military grade steel has to be imported because no-one here makes it anymore.
I believe that our rare-earth materials for missile guidance are imported. Magnaquench was bought my the chicoms and then divested the rare earth division and that division merged with a canadian firm. I suspect the chicoms have that company riddled with spies.
