Trump has just over a year to completely destroy the FBI and CIA, because if he loses the midterms, the old establishment will come back for him

Midterms?
Trump is generating enough unrest to pretend he needs a larger military presence in blue states and cities.
He is creating a problem so he can pretend to solve it. Once he declares martial law, elections will be "postponed".
He has about a year and a half. Plenty of time...
