Is this actually a Geezer reference? [OT]

I was listening to a podcast (Freakonomics, if anybody’s curious) about the Cold War; and when somebody mentioned Khrushchev the host cut in, for the audience’s benefit, with “That’s Nikita Khrushchev, the leader of the Soviet Union during the Cold War.”

Does anybody, particularly somebody listening to a podcast about the Cold War, need to have Khrushchev identified? Is it all that far out of the collective consciousness?
