In the February 1945, the U.S. President Franklin Roosevelt, British Prime Minister Winston Churchill, and Soviet Premier Joseph Stalin met at an old Romanov palace in Crimea, which had once been enjoyed by Tsar Nicholas II and his family. Over eight days the 'Big Three' discussed and debated issues of vast international importance - such as the endgame of the war against Nazi Germany, the constitution of the United Nations, the price of Soviet entry into the war against Japan and the new borders of Poland. Diana Preston joined me on the podcast to discuss this remarkable event. She gave me an inside picture of eavesdropping amongst the delegates, the dwindling health of Churchill and Roosevelt, the laborious dinners with endless Russian toasts, and whether Yalta was really a turning point in 20th century history.
