This feels like what happens when the selection pressure isn't there. Building for "the next war" (or more broadly "the future") is always bound to be an utter boondoggle, because despite your best intentions and the most strenuous furrowing of your eyebrows you'll have literally no fucking idea what the actual demands of that situation will be. You have to react, that's it. Trying to predict is futile. So better to try to set yourself up to react better?
