I agree as far as Small Arms and light ordinance goes - it is a shame that we put that into the hands of an entity that is a threat to other Countries around the world.
The true winners after 20yrs were the Private Contractors and some secondary Russian Arms dealers selling their obsolete junk Heap to the Afghans bought with Good Ol, donated, US dollars.
As far as the military Aircraft - What product in our inventory doesn't require a few hours of maintenance, preventative maintenance, and R&R of parts here and there for every couple of hours flown?. . . . lol I am sure we didn't leave them All the Ferrari's of the Fleet. . . .lol In time those will be as effective as Iran's Airforce trying to keep the F4s, F5s, F14s and a dozen other Aircraft flying.
