Our “intelligence” establishment has managed to continue to produce a long line of Cold War clones without imagination, intellect or policy skills. They have survived by dint of simply repeating what they are told by their real masters, MI6 and the CIA.
They ably reflect the paranoid ignorance of those bodies that have failed almost completely to ever get any intelligence assessment anywhere near the mark.
But, of course, such people flourish in agencies that have no outside assessment and oversight. They cover their failures in secrecy justified by “national security”. Good luck to this new boss, she is definitely going to need it!
