If you don't believe in the power and corruption of the military procurement industry and the military itself, then your comment is so unrealistic as to be deluded.

If you do believe in it, then it's simply irrelevant. Given the other reasons that the US military is spent with profligacy on US manufactured goods, maintaining 'truck know-how' does not register. If the know how consideration did not exist the money would still be spent in exactly the same way.
