It’s simple. Not every penny spent on defense actually defends us, nor is wasting money like every other Big Government department serving anything worth serving.
Hmmm, not everything is a “waste”....
some of us worked in the factories designing and making things like F-14, F-15, F-18 radars, B-52 infrared sensors, stuff like that.....
and still work in the factory designing and making smaller versions of these.
Been doing this for 33 years, need 10 more to retire
