&quot;I don&#x27;t want the military failing hard and failing fast. Make it work, make it work well, and then don&#x27;t mess with it.&quot;<p>This presumes the mission, terrain, and enemy remains static, which has really never been the case.  What worked in WW2 isn&#x27;t often going to be effective for today&#x27;s problems.<p>Sure there are jobs that are nearly eternal, from which we should pick proven designs, doctrines.  But especially in wartime, a &quot;fail fast, fail cheap, and learn quickly&quot; is exactly what I would want in a military to complement the decades of bureaucratic planning that preceded in peacetime.
