Significance of Winston Churchill's speech in 1946

On March 5, 1946, Winston Churchill gave his “iron curtain” speech in Fullton, Missouri. In his speech, he included:

From Stettin in Baltic to Trieste in Adriatic an iron curtain has descended across the continent

I do not believe Soviet Russia desires war. What they desire is the fruits of war and the indefinite expansion of their power and doctrines…

This speech, meant to broadcast the new danger, had a multi-point purpose. He felt that the Soviets might want expansion but not war, which refers to his ability to have discovered the roots of the emerging issues—Soviet territorial motivations. In turn, he warned about the anticipated cold war following World War II, resulting from the “iron curtain.” Also, he believed in order to have stability, American involvement would be required. It was not just a warning but also a plea for peace. His speech was later supported by Russia’s failure to keep its promise to remove its troops from Iran.
