You have a funny idea of "benefit to society." We don't get much benefit from the military except the ability to bomb countries we've barely heard of with incredibly expensive weapons we've never seen for reasons we don't understand.
The military is like insurance. You bitch about paying for it until the time comes when you NEED it. Then you're damned glad you have it. In fact, the BEST military is one so powerful, so skilled, and so feared, that no one ever tests it by agressing against you to begin with.
