It’s quite simple, really. It’s human nature to believe that the guy across the table with think, and act, as you do. Now take a look at the list: Putin, Hitler, Stalin and Abu Bakr al-Baghdadi. Do those guys look like rational actors?
I think it was the Finns that managed to wiretap Hitler, and the recording survived.
Hitler missed his calling as an actor, because the he came across as quite normal, outside of the Fuhrer persona.
Granted, a brief, translated recording belied what he really was, so I can understand how the "best and brightest" would think it vulgar to add "but verify" to dealings psycho- and sociopaths that are "one of them".
