Winston Churchill's "Iron Curtain" Speech

In March of 1946, Winston Churchill delivered this speech at Westminster College in Fulton, Missouri. His message served as a stern warning of the intentions/aspirations of the Soviet Union. Although Churchill usually gets credit for the term "iron curtain," at least one journalist (David Maraniss of The Washington Post) credits Joseph Goebbels (Nazi propaganda minister) for first using it in his writing. Regardless, the Churchill's speech is a powerful one and well worth listening to. I am interested in your reactions.
