Why precisely is having the worlds largest military bad? Do you think it doesnt add any value? It seems theres a lot of people outside of America who'd like to see it shrunk for very bad reasons.
Why not keep the military and solve our problems without it? We need it to be safe now, and until we've already solved our problems, we'll still need it.
Obviously it doesn't always work well and it definitely causes problems, doesn't mean we should get rid of or even reduce it.
