I've done a lot of googling on this guy and either the truth is scrubbed, or I'm landing on soviet propaganda, OR there's not much evidence that he even worked for the KGB. The guy was a journalist and played up this narrative in order to get the attention of the public eye. I'm not saying that everything he said was bullshit. Do nation states at odds actively try to stabilize each other? Of course. But seems to me like he was more of a creative story teller than anything else.
