Actually it is not “ documented”
It is presumed
You know what deep state wants you to know and you think what they want you to think
Putin= Ex KGB. bad. Black hat. Murders spies - after they are pardoned and traded
Because thats good for future negotiations and getting agents to flip ( not)
Western counterparts = white hats. Like the virtuous John Brennan James Clapper and the UK spy operation in the USA run by and for the DNC and obama. Would never murder or do false flags to achieve their goals.
You’d have to be an extremely dense person to believe that anybody else or any entity had any motivation to poison this enemy of Russia.
Same goes for Alexander Litvenenko in a similar situation of a former Russian spy.
Same goes for several Russian journalists who didn’t tow the Putin line in Russian media.
We still have our “useful idiots”, when it comes to protecting authoritarian tyrants like Putin.
Our real condition wrt the Ruling Class/Power Elite/Secret Team/Deep State is terrifying if you let yourself obsess about it.
Secret Power Centers have deep and diverse roots and murderous allies. You are correct about the almost absolute mind control which generally goes unnoticed. Our government has acted like a mafia for a long time basically unchecked. Who even knows what schemes are afoot? Not even the Director-McCord -was aware of the plots to kill Castro or the CIA-Mafia links to carrying out them.
