we are struck by the fact that the physical side of the enemy is, in theory, perfectly knowable and predictable.
Yes that and several things in the Prometheus Process.

Also from "Battlefield of the future" Chap 4 on Airpower Theory for the 21st century (which contains a great many of the points in Warden's current article) looking from the other direction:

When we want more information, we pull out subsystems like electrical power under system essentials and show it as a five-ring system. We may have to make several more five-ring models to show successively lower electrical subsystems. We continue the process until we have sufficient understanding and information to act. Note that with this approach, we have little need for the infinite amount of information theoretically available on a strategic entity like a state. Instead, we can identify very quickly what we don’t know and concentrate our information search on relevant data.
Which indicates that while we don't need information about everything, relatively simple decomposition will provide all the information one might need. Getting to what Ken brings up, this is a very Newtonian, mechanistic view of the world, which only applies to a small subset of physical systems, like electrical grids.
