Answer:
The answer is true.
Step-by-step explanation:
The phrase "Iron Curtain" was used by Winston Churchill in a speech he delivered on March 5, 1946, in Fulton, Missouri. In this speech, Churchill warned of the growing division between the Soviet Union and Western Europe, and he used the phrase "Iron Curtain" to describe the physical and ideological barrier that was being erected between the two regions. Churchill's use of the term helped to solidify the idea that Eastern Europe was becoming a Soviet-controlled sphere of influence, and it marked the beginning of the Cold War, a period of political tension and military competition between the Soviet Union and the West that lasted for several decades.
