In 2007, well before the term Deep State entered the common lexicon, I sketched the interconnected public-private pieces of the Deep State, which I termed the elite maintaining and extending global dominance. This diagram doesn't make all the connections or list all the consequential nodes of influence of course, but you get the idea: elected officials, i.e. "democracy," play a modest role in the entire structure, which displays remarkable continuity regardless of which politicians and parties are currently in power.
That's the whole idea, of course: continuity that can't be disrupted by an election.
