He was once the bloody-handed dictator of the former Soviet Union, back when Elvis was the King of Rock'n'Roll. He was ably portrayed by Bob "Eddie Valiant" Hoskins in 2001's Enemy at the Gates, about the Battle of Stalingrad. If you look him up in communist Wikipedia, they will try to persuade you that he was a saint, slightly to the right of Mother Theresa.

(Just now Wikipedia has its hand out, begging for contributions. I metaphorically spit in that hand, and would do it in person if I could.)

The point here is that, when Khruschev briefly visited the United States (he was disappointed because they wouldn't let him go to capitalist Disneyland) he famously predicted that the American people themselves would eventually raise the communist flag over their own country. Everybody at the time thought that was simply hilarious.
