I just want to add a caveat (while basically agreeing with frezik) that proponents of the unitary executive theory thought that Bill Barr was a total crackpot. So, it’s more like Barr was trying to rehabilitate fascism through an already existing term that makes fascism sound respectable.
Yeah I think for fascists the opportunity for becoming a little mini-dictator over their respective area of the state is very tempting.
