‘From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the continent.’ These words - spoken by Winston Churchill on 5 March 1946 to an audience including President Truman in Fulton, Missouri - can be seen as both a symptom and a catalyst of the collapse of relations between the western allies and the Soviet Union. But what drove Churchill to make this speech? What can it tell us about the relationships between Churchill, Stalin and Truman? How did it intertwine with the fates of countries such as Iran and Turkey? And what impact does its shadow have today? Dr Warren Dockter is the author of ‘Winston Churchill and the Islamic World’, and editor of ‘Winston Churchill at the Telegraph’. In this anniversary episode he speaks to James about this remarkable speech.© PA Images / Alamy Stock Photo See acast.com/privacy for privacy and opt-out information.
