Question

How did the phrase reinforce Churchill’s overall message in this speech?

Answer 1

 Churchill’s “iron curtain” phrase immediately entered the official vocabulary of the Cold War. U.S. officials were less enthusiastic about Churchill’s call for a “special relationship” between the United States and Great Britain.

Answer 2

The phrase illistrates Churchill's message that Europe is divided and the USA must take action against the USSR. The phrase also creates a mental image that made people fear the Soviet Union. It also made people want to help free/save the people whom were trapped in the "Iron Curtain"
