The theory of the 'good guys' (the scare quotes aren't hedging, they're just being careful to avoid ideological framing of the discussion), Lind in particular, is rapidly adjusting to the new threat model. That was the thrust of my point to the other commenter here. There's an interesting parallel in that countering terrorism and counterinsurgency are largely reactionary by their very nature, and the 'good guys' have been left reacting to the new model of warfare in itself in, say, the last decade. People do disagree with Lind on fourth-generation warfare, for what it's worth.
We're "catching up," not "innovating" on the battlefield today. That's the big lesson here.
