See "Deep State" and "Deep state conspiracy theory in the United States" – bearing in mind that Wikipedia is known to be vetted by the  CIA and other Establishment/intelligence agencies, as co-founder Larry Sanders has confirmed; see here, full interview with Glenn Greenwald on July 31, 2024 here, other interviews here. I 've never liked the term "deep state" because it implies that there is another one; see "Deep State Doublethink" and "From Transparent Conspiracy to In-Your-Face Fascism."
