John Kennedy was lectured and threatened by Nikita Krushchev on their first meeting in Vienna. In fact, JFK was thoroughly shaken up by the diatribe.
Krushchev left Vienna with the impression that Kennedy was a weakling. And that led to the introduction of nuclear missiles into Cuber.
Since it demonstrated a serious failing in a Democratic leader, of course the MSM has not (never did) publicize the scolding that JKF got.
In fact, if JFK didn't admit the occasion himself, it may have remained unknown to the general public. To his credit, JFK took his lumps and committed himself to NEVER being in that position again!
