If there is one thing that an ex-KGB boss cannot stand is a supposed intelligence agency that cannot keep it's secrets. Whilst one can claim that there is nothing in the Wikileaks document that is sensationally revelatory the very fact that it is written in black and white in a secret document has the effect of imprinting it in the public conciousness. Putin will not tolerate this and it will amplify the suspicion and mistrust that are part of the DNA of any trained secret agent. Suggestions that he is in charge of a mafia state and that he has a undeclared wealth of $40 billion
will make the Prime Minister wonder if the Americans are not mischief making to scupper his popular image of a man fighting corruption whilst reigning in oligarch power. It will be seen as a deliberate attempt to undermine his power. This does not bode well for US-Russia ties.
