According to the journalist Robert Worth, "The expression deep state had originated in Turkey in the 1990s, where the military colluded with drug traffickers and hit men to wage a dirty war against Kurdish insurgents".[10]
In The Concealment of the State, Professor Jason Royce Lindsey argues that even without a conspiratorial agenda, the term deep state is useful for understanding aspects of the national security establishment in developed countries, with emphasis on the United States. Lindsey writes that the deep state draws power from the national security and intelligence communities, a realm where secrecy is a source of power.[11]:35-36 Alfred W. McCoy states that the increase in the power of the U.S. intelligence community since the September 11 attacks "has built a fourth branch of the U.S. government" that is "in many ways autonomous from the executive, and increasingly so."[12]
According to David Gergen, quoted in Time magazine, the term has been appropriated by Steve Bannon and Breitbart News and other supporters of the Trump Administration in order to delegitimize the critics of the current presidency.[15] The 'deep state' theory has been dismissed by authors for The New York Times[16] and New York Observer.[17] University of Miami Professor Joseph Uscinski says, "The concept has always been very popular among conspiracy theorists, whether they call it a deep state or something else."[18]
Former NSA leaker Edward Snowden has used the term generally to refer to the influence of civil servants over elected officials: "the deep state is not just the intelligence agencies, it is really a way of referring to the career bureaucracy of government. These are officials who sit in powerful positions, who don't leave when presidents do, who watch presidents come and go ... they influence policy, they influence presidents."[19]
In an opinion piece by linguist Geoffrey Nunberg, he said the "deep state" is an "elastic label – depending on the occasion" and its "story conforms to the intricate grammar of those conspiracy narratives". He also contrasted the change in the "twin bogeys of conservative rhetoric", from bureaucratic "meddlesome bunglers" of "big government" to "conniving ideologues" who "orchestrates complex schemes".[20]
On March 20, 2018, Sen. Rand Paul said "Absolutely there is a deep state because the deep state is that the intelligence communities do not have oversight." He continued, "There is no skeptic" [emphasis in original] among the four Republican and four Democratic Senators "who are supposedly" providing oversight, so that the intelligence communities, “with their enormous power ... have become a deep state."[21][dead link] On December 4, 2018, Paul, in commenting on the CIA Director briefing only those eight Senators rather than the entire Senate, added "The deep state wants to keep everyone in the dark. This is just ridiculous!"[22] On December 10, 2018, he said "The very definition of a 'deep state’ is when the very people, congressional leaders – people who are elected by the people – are not allowed to hear the intelligence."[23]
