A May 1943 article in '' Signal '' , a Nazi illustrated propaganda periodical published in many languages , bore the title " Behind the Iron Curtain " . It discussed " the iron curtain that more than ever before separates the world from the Soviet Union " . The German Minister of Propaganda Joseph Goebbels wrote in his weekly newspaper '' Das Reich '' that if the Nazis should lose the war a Soviet-formed " iron curtain " would arise because of agreements made by Stalin , Franklin D. Roosevelt and Winston Churchill at the Yalta Conference : " An iron curtain would fall over this enormous territory controlled by the Soviet Union , behind which nations would be slaughtered " . The first recorded oral intentional mention of an Iron Curtain in the Soviet context occurred in a broadcast by Lutz von Krosigk to the German people on 2 May 1945 : " In the East the iron curtain behind which , unseen by the eyes of the world , the work of destruction goes on , is moving steadily forward "
