I would rather spend $1M on peoples jobs than on parts for an Abrams Tank.
"Defense spending", when it is brought up now, means what it IS now, not what it could become. What it is now is fat-cat contracts, overpriced mercenaries, and an overtaxed "professional" military that is made up of less than 1% of our population on a VOLUNTARY basis.
It is too disconnected and too inefficient an animal to handle our current problems. I was hoping this would subside after the Russian Menace was dispelled, but government agencies just found someone else to fear and dumped money on it.
