I don't think it's that simple: stuff costs more in the US vs other big military spenders, large != effective, etc. If the US cut its military budget, it would have to give up capabilities, and that will have bitter consequences (e.g. the liberal order will shrink even further (e.g. goodbye Ukraine, Taiwan, Baltics), China owns the seas, etc.).
