Trump was an element of controlled pseudo-opposition put in place by the same deep state, under the supervision of Henry Kissinger. The Flynn clan (father and son), which orchestrated the "Q-Anon" hoax, has NSA and psy-ops background. It's not that the deep state Trump was denouncing doesn't exist, nor that its members aren't degenerates responsible for horrendous crimes. It's that Trump never was the person willing and capable of confronting let alone eradicating it.
But he instead took on a ride some of the alienated segments of US citizenry, those with a revolutionary potential, all the while of delegitimizing the anti-deep state discourse in the eyes of the more educated segments still loyal to the system, because of his clownish antics and due to some of the more outlandish claims mixed with true ones that "Q-Anon" and similar Trumpist propaganda outlets were peddling.
This is one of the tactics employed by the oppressive US system: when threatened by the consequences of its own manhandling and exploitation of its subjects, it will prop up a controlled opposition figure whose strings it pulls and whom it does not have to fear the least, in order to misdirect and neutralize brewing popular anger.
Another tactic is the so-called "horizontalization" of the social struggle, i.e. the redirection of the main target of popular wrath, away from the entirety of the ruling class and towards parts of society iself (and particularly of the working class), following the divide and rule principle. Which is exactly what occurred under Trump with artificially engineered and entertained divides such as "left vs right", "racists vs anti-racists", "whites vs blacks and immigrants" etc.
