There are rank-and-file members of the western intelligence community that watch/read Zeihan just so they know what their own leadership is ingesting.
He also seems to be veering into fabulism. He's recently said in multiple interviews that there's a clothing factory in North Carolina that is so automated that only 2 "guys" are needed to run it. Raw cotton comes in at one end, and finished clothing comes out at the other (hence Chinese labor is not needed to stitch clothes, hence China is going to collapse any day now).
Why do I believe this is fabulism? He never names this company. And the story has evolved. In earlier interviews he used to say that cloth comes out at the other end. But in a couple of recent interviews he's said finished clothing comes out at the other end.
