This is the primary reason the us military budget should go from 1.5 trillion to 0.5 trillion. If we shifted to drone dominance the cost would go way down, we’d have a stronger military, and we could use that extra trillion to pay down debt, fund more healthcare, share profits with US citizens, the list of possible amazing things is huge.
Will we do this? Maybe eventually but not while we have big strong dumbass in charge.
