Derin devlet named the Turkish network of military, intelligence, and organized crime exposed by the 1996 Susurluk crash, a car wreck containing an MP, a police chief, a wanted hitman, and a beauty queen, the state and the underworld in one Mercedes. Peter Dale Scott carried the term into English in 2007's The Road to 9/11, applying it to America's security state and its private partners. Mike Lofgren's 2014 Anatomy of the Deep State mainstreamed it, and by 2017 it was a presidential catchphrase.
The story nobody designed: Scott was a left-leaning Berkeley scholar of covert power, and his term escaped leftward seminars through, of all people, Alex Jones, who platformed him and carried deep state to the conspiratorial right. Within a decade the left's critique of the military-industrial complex had become the right's name for the FBI. Scott watched his import get, in the words of one historian, co-opted and vulgarized, and kept giving interviews anyway.
The structural claim: any state with a permanent security apparatus has a deep state by definition, power not derived from the constitution but outside and above it, in Scott's own phrase, so the only real question is how deep yours is. The skeptics' counter: the term is unfalsifiable fog, every bureaucracy resisting a politician becomes proof of the plot. Between them sits the Monmouth poll of 2018: three-quarters of Americans agreed unelected officials secretly direct national policy.
Every faction that gains power discovers the deep state was real and was someone else's. Is the term a discovery or a mirror?
