Carver says it's understandable why the speech, which was about the "special relationship" between the U.S. and Great Britain, was remembered for two other words: "iron curtain."
"Unfortunately, at the time, people thought a 'special relationship' meant alliance. And they were war-weary and didn't want to go back to war. And so people latched on to the words 'Iron Curtain,'" Carver said.
Carver says the reason Churchill used that term was to illustrate "the lack of transparency that was going on in the European countries that Russia was taking over." An iron curtain was traditionally deployed in theatres to protect the audience in the event that a fire broke out on stage.
