During the Second World War, President Franklin Roosevelt, Premier Joseph Stalin, and Prime Minister Winston Churchill exchanged hundreds of cables and held two summit meetings, coordinating the vast allied effort to defeat Nazi Germany and Imperial Japan. David Kennedy, Stephen Kotkin, Andrew Roberts and Peter Robinson discuss why the peaceful new international order that the three agreed to establish after the conflict turned instead into the Cold War. This discussion is the fifth of speaker series "A Century of Ideas for a Free Society." For more information on the series and related upcoming events, visit: hvr.co/2HK3C6W
