I found this to be a remarkably uninsightful work. He somehow negates the inherent drama of war with the milquetoast prose and myopia of an academic. Much of what he says is in fact false, presumably because he is far from the action and relies on Clausewitz as a crutch for thought.

The key nodes to control have to do with supply chain, energy and information; ie depots, road and rail, bridges, factories, substations and data centers or satellites.

Ukraine has severely weakened Russia by attacking those points, as Russia has Ukraine.

Beijing could well defeat Taiwan (and the US by proxy) by controlling its sea lanes, cutting its cables, and jamming its radio spectrum.
