I'm gonna go out on a limb here and suggest that Jack was making a more generalized statement as to the manufacturng base(or lack thereof) that seems to remain here in the US. We might not be buying weapons from the Chinese, but we sure as hell are buying raw material from just about everyone! Raw steel production in the US is a very faint shadow of what it was after WWII...depending on the study you read, it's anywhere from 25% down to as little as 2% of WWII capacity.
